• Facing delay in mic audio while using ffmpeg with h264_nvenc encoder [closed]

  30 avril 2023, par Aniket Bose

  I am trying to capture my windows10 desktop with desktop duplication api and on-gpu D3D11 textures, in the form of ffmpeg D3D11VA frames @60 fps. Required command is given here. On top of that I am trying to also intercept my mic audio. For that I am using this command,

  


  ffmpeg -init_hw_device d3d11va -filter_complex ddagrab=framerate=60 -f dshow -i audio="Microphone (High Definition Audio Device)" -c:v h264_nvenc -rc vbr -cq 24 -qmin 24 -qmax 24 -profile:v main -b:v 0K output.mp4


  


  After the desktop capture process when I am watching output.mp4 I am facing an audio delay. More Precisely my mic audio is coming after 28/29 video frames. ie. (28/60)*1000 = 466 ms delay in audio.

  


  I tried to capture @30fps but no improvement. Now I am getting 14 frames delay ie. (14/30)*1000 = 466 ms delay in audio.

  


  After some research I came to know about keyframe intervals. at default h264_nvenc uses 200 sec keyframe interval. So i tried to lower that with the -g option of h264_nvenc encoder. No improvement here too.

  


  One possible solution could be to delay my video using -itsoffset option. These stack overflow and superuser solutions only work with pre-recorded videos,

  


  ffmpeg delay video in overlay

  


  In ffmpeg, how to delay only the audio of a .mp4 video without converting the audio ?

  


  But I am capturing and encoding on the go (ie. at same time).

  


  I am a novice at video editing and ffmpeg. I am using latest release build from gyan.dev.

• GDPR Compliance Checklist : A Detailed Walkthrough

  14 septembre 2023, par Erin — GDPR

  As digital transformation drives global economies, data has become a valuable currency to businesses of all shapes and sizes. As a result, the complex issue of data privacy is often in the spotlight.

  The General Data Protection Regulation (GDPR) is the key legal framework in the European Union to protect individual privacy and regulate business data handling. 

  Compliance with the GDPR is not just a legal mandate, it’s also good business. An 86% majority of users want more control over their data and 47% of users have switched providers over data privacy concerns.

  To help guide your business decisions around user privacy, this article will cover the key principles of GDPR, including a comprehensive GDPR compliance checklist.

  The key principles and requirements of GDPR

  Before we can translate GDPR’s objectives into practical steps, let’s begin with the defining features and key principles.

  GDPR : An overview

  The GDPR bolsters and unifies data protection standards for everyone within the EU. Enacted in 2018, it represented a seismic shift for companies and public authorities alike in protecting personal information. Its primary objective is to offer greater control to individuals over their data and to hold organisations accountable for its protection.

  GDPR establishes a legal framework that mandates corporate compliance with key principles to ensure user data security, transparency and choice. It sets the terms for your organisation’s privacy practices and the landscape of legal obligations you must navigate in data handling. 

  Key principles of GDPR

  There are seven core principles pivotal to GDPR compliance, which provide a roadmap for ethical and legal data practices.

  

  • Lawfulness, fairness and transparency : This principle demands lawful and fair processing of personal data. Companies should be transparent about their data processing activities, providing clear information in an accessible form.
  • Purpose limitation : Personal data should be collected for explicit, legitimate purposes and not further processed in a way incompatible with those purposes. This demands careful planning of data processing activities.
  • Data minimisation : Companies should only collect personal data that are necessary for their specified purposes, as anything more than this is illegal. This principle emphasises the importance of limiting scope, rather than performing blanket data collection.
  • Accuracy : This principle calls for maintaining data that is accurate, up-to-date and not misleading. Regular internal audits and updates are crucial to following this principle.
  • Storage limitation : Personal data should only be kept for as long as necessary for the purposes for which it was collected. This underscores the need for a detailed retention policy in your GDPR compliance efforts.
  • Integrity and confidentiality : Companies should protect personal data from unauthorised or unlawful processing and accidental loss or damage. Your organisation’s technical security measures play a vital role in this.
  • Accountability : Organisations should be able to demonstrate their compliance with GDPR principles. This underscores the importance of records of processing activities and regular audits as part of your compliance checklist.

  The importance of GDPR compliance for businesses

  Embracing GDPR compliance isn’t merely a matter of avoiding penalties — it’s a commitment to principles that reflect integrity, transparency and respect for personal data. At Matomo, we champion these principles, empowering companies with powerful and compliant web analytics. We make the compliance journey accessible and straightforward, making sure website analytics aligns with legal obligations and ethical practices.

  The implications of non-compliance

  It’s easy to highlight the dramatic fines imposed on tech giants such as Google and Meta. However, it’s essential to recognise that GDPR compliance extends to all companies, including small businesses — for whom even smaller fines can have a significant impact.

  The implications of non-compliance aren’t limited to financial penalties alone, either. Failing to meet obligations can tarnish reputations, erode trust and hinder business activities. Non-compliance could lead to a breach of privacy policy, causing a ripple effect that may be challenging to overcome.

  The potential benefits of being GDPR compliant

  Adhering to GDPR regulations is more than a checkbox on a form — it’s a comprehensive approach to handling personal data responsibly. It fosters trust, opens doors to European customers and builds enduring relationships with individuals whose rights are protected. In fulfilling these obligations and practices, businesses not only meet legal requirements but also foster a culture of ethical conduct and business success.

  Comprehensive GDPR compliance checklist

  Ensuring GDPR compliance may seem like a complex task, but this detailed checklist will simplify your journey. From consent management to data security, we’ve got you covered.

  

  Establish personal data collection and consent management

  When it comes to GDPR compliance, not all consent is created equal. Two distinct forms exist : explicit consent and implied consent. But what exactly sets them apart, and why does it matter to your organisational measures ?

  Explicit consent from users means that the individual has unequivocally agreed to the processing of personal data. It’s an unambiguous agreement, often obtained through a deliberate action like ticking a box. Details are paramount, as the person giving consent must be fully informed about the processing activities.

  • Inform clearly : Use plain language to explain how data will be used and be transparent about processing practices.
  • Obtain active agreement : Use forms or checkboxes (not pre-ticked boxes) to ensure active participation and that you are obtaining explicit user consent.
  • Document it : Keep records of consent, including when and how it was obtained, as a crucial part of your compliance efforts.
  • Facilitate withdrawal : Use consent mechanisms that allow for easy withdrawal of consent for users who decide to opt out.
  • Manage consent forms : Tools like Matomo’s Consent Management Platform can provide accessible forms that not only enhance transparency but also empower individuals, allowing them to feel in control of their details and rights.

  Facilitate data subject rights and access requests

  GDPR emphasises individual rights by empowering users with control over their personal data processing. Here’s a succinct breakdown :

  • Know the rights of individuals : GDPR outlines individual rights such as data access, error rectification, erasure and data portability, allowing individuals to guide how their details are used, processed or shared.
  • Simplify complying with access requests : Companies must respond to access requests efficiently, usually within one month, without undue delay, reflecting organisational measures of respect.
  • Employ ethical and compliant digital analytics : As a leader in ethical web analytics, Matomo subtly aids in compliance efforts, protecting privacy without compromising functionality.

  These practices align with a modern understanding of privacy, emphasising more than legal obligations. By employing Matomo, companies simplify the processing of access requests, which fosters transparency and user control over personal data.

  Implement clear data privacy practices

  Data privacy and consent mechanisms are key tools for compliance. Crafting a comprehensive privacy policy helps protect individuals’ rights and provides integrity in personal data processing. Designing sites and applications with data protection in mind ensures your compliance from the ground-up.

  • Create an easy to understand privacy policy : Create a clear, GDPR-compliant privacy policy that details processing activities, storage limitations and organisational measures, all in plain language. 

  By implementing these steps, companies not only adhere to their legal obligations but also foster an inclusive community that values privacy and ethics. Whether you’re an IT professional or marketer, Matomo’s platform can guide you through the maze of GDPR complexities, inspiring positive change towards responsible data handling.

  Implement data storage limitations and robust security

  Data storage and security are foundational elements of compliance efforts. Companies must foster a proactive approach to preventing data breaches by understanding potential cyberthreats and enforcing appropriate security controls across applications and infrastructures.

  

  • Implement storage limitations : Define limitations on time and scope to avert undue retention and protect personal details.
  • Embrace technical security : Utilise secure processes like encryption, access controls, firewalls and so on, bolstering protection by design.
  • Establish a comprehensive security policy : Align security practices with privacy laws and regulations, including GDPR.
  • React swiftly to personal data breaches : A security breach requires an immediate response, without undue delay, to honour legal obligations and maintain customer trust. Develop a plan for notifying supervisory authorities and affected individuals promptly in the event of a personal data breach.

  Security measures for personal data are about more than just fulfilling legal obligations — they’re about building a safe and ethical digital ecosystem that instils confidence in customers.

  Keep cross-border data transfers in mind

  Cross-border data transfers present a unique challenge, with increased complexity due to varying data privacy laws across regions. You must understand the respective regulations of participating countries and align your compliance practices appropriately to respect all that are relevant to your organisation. 

  For example, data privacy laws in the US are generally more lax than the GDPR so US companies taking on EU customers must hold themselves to a higher standard, with stricter controls placed on their data processing practices.

  • Evaluate third-party services : For companies utilising global networks of third-party services, be sure to select providers that maintain ongoing knowledge and vigilance towards privacy law compliance. Platforms like Matomo that innately prioritise transparency and privacy, have implemented robust security measures, and document transfers diligently are worth considering. 

  Conduct internal audits and compliance checks

  Compliance is not a “one and done” setup, but an ongoing journey requiring regular internal audits. Systems settings can drift over time, and datasets can become increasingly complex as companies scale. Human error happens, too. Audits identify gaps in your compliance efforts to guide actionable improvements. 

  • Conduct regular audits : Stay proactive with internal audits and systematic monitoring, adapting policies to align with privacy laws. Clarity in privacy notices and cookie banners fosters confidence, while regular assessments ensure alignment with GDPR requirements.
  • Ensure transparency : Platforms like Matomo simplify audits, offering valuable insights and support for ethical web analytics and transparency. The right platform can increase visibility and make generating your reports easier. Integrating these processes guarantees GDPR-aligned measures while emphasising data ownership and customer-centric values.
  • Educate and train staff : Engage in ongoing staff education and training on GDPR compliance, privacy policies, and their related responsibilities.

  

  Case study : GDPR compliance in action

  Achieving compliance with the General Data Protection Regulation (GDPR) stands as a paramount concern for businesses worldwide. Both small and large companies have embarked on this journey, implementing measures and revising privacy policies to conform to these regulations.

  Typeform

  Based in Ireland, Typeform, a company dealing with online forms, took GDPR compliance very seriously. Here’s how they achieved it :

  1. Conducting a data protection impact assessment (DPIA) : This vital step helped them assess personal data breach risks and enabled systematic monitoring of potential challenges.
  2. Implementing technical and organisational measures : Security measures such as encryption, access control and drafting a security policy reinforced their personal data processing mechanisms.
  3. Revamping privacy policy : They transformed their privacy policy with accessible, plain language, making it clear and user-friendly.
  4. Appointing a data protection officer (DPO) : This aligned with their core activities and strengthened their compliance efforts.

  The benefits for Typeform were profound :

  • Enhanced customer trust and confidence
  • Reduced risk of fines and penalties
  • Bolstered data security and privacy
  • Improved brand reputation, positioning them favourably among European customers

• A Comprehensive Guide to Robust Digital Marketing Analytics

  30 octobre 2023, par Erin

  First impressions are everything. This is not only true for dating and job interviews but also for your digital marketing strategy. Like a poorly planned resume getting tossed in the “no thank you” pile, 38% of visitors to your website will stop engaging with your content if they find the layout unpleasant. Thankfully, digital marketers can access data that can be harnessed to optimise websites and turn those “no thank you’s” into “absolutely’s.”

  So, how can we transform raw data into valuable insights that pay off ? The key is web analytics tools that can help you make sense of it all while collecting data ethically. In this article, we’ll equip you with ways to take your digital marketing strategy to the next level with the power of web analytics.

  What are the different types of digital marketing analytics ?

  Digital marketing analytics are like a cipher into the complex behaviour of your buyers. Digital marketing analytics help collect, analyse and interpret data from any touchpoint you interact with your buyers online. Whether you’re trying to gauge the effectiveness of a new email marketing campaign or improve your mobile app layout, there’s a way for you to make use of the insights you gain. 

  As we go through the eight commonly known types of digital marketing analytics, please note we’ll primarily focus on what falls under the umbrella of web analytics. 

  1. Web analytics help you better understand how users interact with your website. Good web analytics tools will help you understand user behaviour while securely handling user data. 
  2. Learn more about the effectiveness of your organisation’s social media platforms with social media analytics. Social media analytics include user engagement, post reach and audience demographics. 
  3. Email marketing analytics help you see how email campaigns are being engaged with.
  4. Search engine optimisation (SEO) analytics help you understand your website’s visibility in search engine results pages (SERPs). 
  5. Pay-per-click (PPC) analytics measure the performance of paid advertising campaigns.
  6. Content marketing analytics focus on how your content is performing with your audience. 
  7. Customer analytics helps organisations identify and examine buyer behaviour to retain the biggest spenders. 
  8. Mobile app analytics track user interactions within mobile applications. 

  Choosing which digital marketing analytics tools are the best fit for your organisation is not an easy task. When making these decisions, it’s critical to remember the ethical implications of data collection. Although data insights can be invaluable to your organisation, they won’t be of much use if you lose the trust of your users. 

  Tips and best practices for developing robust digital marketing analytics 

  So, what separates top-notch, robust digital marketing analytics from the rest ? We’ve already touched on it, but a big part involves respecting user privacy and ethically handling data. Data security should be on your list of priorities, alongside conversion rate optimisation when developing a digital marketing strategy. In this section, we will examine best practices for using digital marketing analytics while retaining user trust.

  

  Clear objectives

  Before comparing digital marketing analytics tools, you should define clear and measurable goals. Try asking yourself what you need your digital marketing analytics strategy to accomplish. Do you want to improve conversion rates while remaining data compliant ? Maybe you’ve noticed users are not engaging with your platform and want to fix that. Save yourself time and energy by focusing on the most relevant pain points and areas of improvement.

  Choose the right tools for the job

  Don’t just base your decision on what other people tell you. Take the tool for a test drive — free trials allow you to test features and user interfaces and learn more about the platform before committing. When choosing digital marketing analytics tools, look for ones that ensure compliance with privacy laws like GDPR.

  Don’t overlook data compliance

  GDPR ensures organisations prioritise data protection and privacy. You could be fined up to €20 million, or 4% of the previous year’s revenue for violations. Without data compliance practices, you can say goodbye to the time and money spent on digital marketing strategies. 

  Don’t sacrifice data quality and accuracy

  Inaccurate and low-quality data can taint your analysis, making it hard to glean valuable insights from your digital marketing analytics efforts. Regularly audit and clean your data to remove inaccuracies and inconsistencies. Address data discrepancies promptly to maintain the integrity of your analytics. Data validation measures also help to filter out inaccurate data.

  Communicate your findings

  Having insights is one thing ; effectively communicating complex data findings is just as important. Customise dashboards to display key metrics aligned with your objectives. Make sure to automate reports, allowing stakeholders to stay updated without manual intervention. 

  Understand the user journey

  To optimise your conversion rates, you need to understand the user journey. Start by analysing visitors interactions with your website — this will help you identify conversion bottlenecks in your sales or lead generation processes. Implement A/B testing for landing page optimisation, refining elements like call-to-action buttons or copy, and leverage Form Analytics to make informed, data-driven improvements to your forms.

  Continuous improvement

  Learn from the data insights you gain, and iterate your marketing strategies based on the findings. Stay updated with evolving web analytics trends and technologies to leverage new growth opportunities.

  Why you need web analytics to support your digital marketing analytics toolbox

  You wouldn’t set out on a roadtrip without a map, right ? Digital marketing analytics without insights into how users interact with your website are just as useless. Used ethically, web analytics tools can be an invaluable addition to your digital marketing analytics toolbox. 

  The data collected via web analytics reveals user interactions with your website. These could include anything from how long visitors stay on your page to their actions while browsing your website. Web analytics tools help you gather and understand this data so you can better understand buyer preferences. It’s like a domino effect : the more you understand your buyers and user behaviour, the better you can assess the effectiveness of your digital content and campaigns. 

  Web analytics reveal user behaviour, highlighting navigation patterns and drop-off points. Understanding these patterns helps you refine website layout and content, improving engagement and conversions for a seamless user experience.

  

  Concrete CMS harnessed the power of web analytics, specifically Form Analytics, to uncover a crucial insight within their user onboarding process. Their data revealed a significant issue : the “address” input field was causing visitors to drop off and not complete the form, severely impacting the overall onboarding experience and conversion rate.

  Armed with these insights, Concrete CMS made targeted optimisations to the form, resulting in a substantial transformation. By addressing the specific issue identified through Form Analytics, they achieved an impressive outcome – a threefold increase in lead generation.

  This case is a great example of how web analytics can uncover customer needs and preferences and positively impact conversion rates. 

  Ethical implications of digital marketing analytics

  As we’ve touched on, digital marketing analytics are a powerful tool to help better understand online user behaviour. With great power comes great responsibility, however, and it’s a legal and ethical obligation for organisations to protect individual privacy rights. Let’s get into the benefits of practising ethical digital marketing analytics and the potential risks of not respecting user privacy : 

  • If someone uses your digital platform and then opens their email one day to find it filled with random targeted ad campaigns, they won’t be happy. Avoid losing user trust — and facing a potential lawsuit — by informing users what their data will be used for. Give them the option to consent to opt-in or opt-out of letting you use their personal information. If users are also assured you’ll safeguard personal information against unauthorised access, they’ll be more likely to trust you to handle their data securely.
  • Protecting data against breaches means investing in technology that will let you end-to-end encrypt and securely store data. Other important data-security best practices include access control, backing up data regularly and network and physical security of assets.
  • A fine line separates digital marketing analytics and misusing user data — many companies have gotten into big trouble for crossing it. (By big trouble, we mean millions of dollars in fines.) When it comes to digital marketing analytics, you should never cut corners when it comes to user privacy and data security. This balance involves understanding what data can be collected and what should be collected and respecting user boundaries and preferences.
