• ffmpeg Batch Replace MP4 Thumbnails

  1er juin 2022, par pglove

  Windows 10, 2022 build of ffmpeg

  


  I found this command to replace the thumbnails on mp4 files :

  


  ffmpeg -i video.mp4 -i image.png -map 1 -map 0 -c copy -disposition:0 attached_pic out.mp4


  


  here :
How do I add a custom thumbnail to a .mp4 file using ffmpeg ?

  


  I have modified it to use jpg instead of png, and have a folder full of videos and images.

  


  ffmpeg -i ###.mp4 -i ###.jpg -map 1 -map 0 -c copy -disposition:0 attached_pic ###-new.mp4


  


  Every mp4 has an alpha-numeric name with a corresponding jpg of the same name.

  


  I generated a list of commands I would need for each file, so I have 100 commands.

  


  If I copy and paste one line at a time it works, but when I copy and paste all 100 lines into the command line on windows it seems like one or two files process as expected, but the rest fail.

  


  I'm pretty sure I'm just missing a step, and any help would be much appreciated turning it into a batch process.

  


  Thanks

  


  *I just tried with 2 lines, the first processed, the second stopped.

  


  Some feedback would be nice if I've posed the question poorly, not provided enough information, or done something else wrong to deserve a downvote already. I don't use forums very often, I try to only ask when I'm stumped, so perhaps my etiquette is poor. I thought I followed correct procedure...

  


• Problem with ffplay from webcam stream using complex filters

  29 mai 2022, par efelbar

  I'm trying to stream video from a webcam (at /dev/video2) through ffplay to scale and recolor it, add some text, and then reduce the number of colors with palettes. I don't get any errors, but running the ffplay command :

  


  ffplay -i /dev/video2 -vf "hflip,\
  colorbalance=\
    rs=0.4:\
    bs=-0.4\
  ,\
  scale=\
    trunc(iw/8):\
    trunc(ih/8)\
  ,\
  drawtext=\
    text=\
      'efelbar':\
      fontcolor=white:\
      fontsize=10:\
      box=1:\
      boxcolor=black:\
      boxborderw=5:\
      x=(w-text_w)/2:\
      y=(h-text_h)/2\
  ,\
  split[s0][s1];\
  [s0]palettegen=\
    max_colors=16\
  [p];\
  [s1][p]paletteuse"


  


  seems to stall, and fails to produce video output.

  


  Running the simpler command ffplay -i /dev/video2 -vf "split[s0][s1];[s0]palettegen=max_colors=16[p];[s1][p]paletteuse", which takes a stream from a webcam and (should) reduce the number of colors, results in it just sitting there without showing the actual output stream. This might just be a performance issue because I'm on older hardware, but it doesn't give output relfective of that.

  


  The output of that command is as follows :

  I'm running this on a thinkpad t420s, so I definitely wouldn't be surprised if my laptop just can't process video that quickly. If that is the case, suggestions for optimizations would be great !

  


• Your Essential SOC 2 Compliance Checklist

  11 mars, par Daniel Crough — Privacy, Security

  With cloud-hosted applications becoming the norm, organisations face increasing data security and compliance challenges. SOC 2 (System and Organisation Controls 2) provides a structured framework for addressing these challenges. Established by the American Institute of Certified Public Accountants (AICPA), SOC 2 has become a critical standard for demonstrating trustworthiness to clients and partners.

  A well-structured SOC 2 compliance checklist serves as your roadmap to successful audits and effective security practices. In this post, we’ll walk through the essential steps to achieve SOC 2 compliance and explain how proper analytics practices play a crucial role in maintaining this important certification.

  What is SOC 2 compliance ?

  SOC 2 compliance applies to service organisations that handle sensitive customer data. While not mandatory, this certification builds significant trust with customers and partners.

  According to the AICPA, “SOC 2 reports are intended to meet the needs of a broad range of users that need detailed information and assurance about the controls at a service organisation relevant to security, availability, and processing integrity of the systems the service organisation uses to process users’ data and the confidentiality and privacy of the information processed by these systems.“

  At its core, SOC 2 helps organisations protect customer data through five fundamental principles : security, availability, processing integrity, confidentiality, and privacy.

  Think of it as a seal of approval that tells customers, “We take data protection seriously, and here’s the evidence.”

  Companies undergo SOC 2 audits to evaluate their compliance with these standards. During these audits, independent auditors assess internal controls over data security, availability, processing integrity, confidentiality, and privacy.

  What is a SOC 2 compliance checklist ?

  A SOC 2 compliance checklist is a comprehensive guide that outlines all the necessary steps and controls an organisation needs to implement to achieve SOC 2 certification. It covers essential areas including :

  • Security policies and procedures
  • Access control measures
  • Risk assessment protocols
  • Incident response plans
  • Disaster recovery procedures
  • Vendor management practices
  • Data encryption standards
  • Network security controls

  SOC 2 compliance checklist benefits

  A structured SOC 2 compliance checklist offers several significant advantages :

  Preparedness

  Preparing for a SOC 2 examination involves many complex elements. A checklist provides a clear, structured path, breaking the process into manageable tasks that ensure nothing is overlooked.

  Resource optimisation

  A comprehensive checklist reduces time spent identifying requirements, minimises costly mistakes and oversights, and enables more precise budget planning for the compliance process.

  Better team alignment

  A SOC 2 checklist establishes clear responsibilities for team members and maintains consistent understanding across all departments, helping align internal processes with industry standards.

  Risk reduction

  Following a SOC 2 compliance checklist significantly reduces the risk of compliance violations. Systematically reviewing internal controls provides opportunities to catch security gaps early, mitigating the risk of data breaches and unauthorised access.

  Audit readiness

  A well-maintained checklist simplifies audit preparation, reduces stress during the audit process, and accelerates the certification timeline.

  Business growth

  A successful SOC 2 audit demonstrates your organisation’s commitment to data security, which can be decisive in winning new business, especially with enterprise clients who require this certification from their vendors.

  Challenges in implementing SOC 2

  Implementing SOC 2 presents several significant challenges :

  Time-intensive documentation

  Maintaining accurate records throughout the SOC 2 compliance process requires diligence and attention to detail. Many organisations struggle to compile comprehensive documentation of all controls, policies and procedures, leading to delays and increased costs.

  Incorrect scoping of the audit

  Misjudging the scope can result in unnecessary expenses and extended timelines. Including too many systems complicates the process and diverts resources from critical areas.

  Maintaining ongoing compliance

  After achieving initial compliance, continuous monitoring becomes essential but is often neglected. Regular internal control audits can be overwhelming, especially for smaller organisations without dedicated compliance teams.

  Resource constraints

  Many organisations lack sufficient resources to dedicate to compliance efforts. This limitation can lead to staff burnout or reliance on expensive external consultants.

  Employee resistance

  Staff members may view new security protocols as unnecessary hurdles. Employees who aren’t adequately trained on SOC 2 requirements might inadvertently compromise compliance efforts through improper data handling.

  Analytics and SOC 2 compliance : A critical relationship

  One often overlooked aspect of SOC 2 compliance is the handling of analytics data. User behaviour data collection directly impacts multiple Trust Service Criteria, particularly privacy and confidentiality.

  Why analytics matters for SOC 2

  Standard analytics platforms often collect significant amounts of personal data, creating potential compliance risks :

  1. Privacy concerns : Many analytics tools collect personal information without proper consent mechanisms
  2. Data ownership issues : When analytics data is processed on third-party servers, maintaining control becomes challenging
  3. Confidentiality risks : Analytics data might be shared with advertising networks or other third parties
  4. Processing integrity questions : When data is transformed or aggregated by third parties, verification becomes difficult

  How Matomo supports SOC 2 compliance

  

  Matomo’s privacy-first analytics approach directly addresses these concerns :

  1. Complete data ownership : With Matomo, all analytics data remains under your control, either on your own servers or in a dedicated cloud instance
