• Unable to Creating Video File from one audio file and single image file in windows form c# using ffmpeg.exe

  25 juillet 2018, par MoonTech

  Hello I created one form for creating video from one mp3 file and one jpg file.
  For this I Wrote this Code but this is not the answer.

   private void button2_Click(object sender, EventArgs e)
  
      {         
  
          string input_audio = @"C:\Users\...\Desktop\test\audio";        
  
  
  
          string outPut = @"C:\Users\...\Desktop\test\outputvideo";
  
          string img= @"C:\Users\...\Desktop\folder image\image123";
  
  
  
          stripAudioTest(img, input_audio,  outPut);
  
  
  
      }
  
  
  
      public void stripAudioTest(string image, string AudioFile, string outputfile)
  
      {
  
          string FFMPEG_PATH = "ffmpeg.exe";          
  
  
  
          string strParam = "-loop 1 -i "+ image+".jpg  -i "+ AudioFile+ ".mp3 -c:v libx264 -c:a aac -strict experimental -b:a 128k -shortest "+ outputfile+ ".mp4";                    
  
  
  
          process(FFMPEG_PATH, strParam);
  
  
  
      }
  
  
  
      public void process(string Path_FFMPEG, string strParam)
  
      {
  
          try
  
          {
  
              Process ffmpeg = new Process();
  
              ffmpeg.StartInfo.UseShellExecute = false;
  
              ffmpeg.StartInfo.RedirectStandardOutput = true;              
  
              ffmpeg.StartInfo.CreateNoWindow = true;
  
              ffmpeg.StartInfo.FileName = Path_FFMPEG;
  
              ffmpeg.StartInfo.Arguments = strParam;               
  
              ffmpeg.Start();
  
              ffmpeg.StartInfo.ErrorDialog = true;             
  
              ffmpeg.WaitForExit();
  
  
  
          }
  
          catch (Exception ex)
  
          {
  
              MessageBox.Show(ex.Message);
  
          }
  
      }

  FYI : mp3 file Duration 5 minutes and 23 Seconds .
  1. I am new in FFmpeg so I don’t have idea how to get out of this.
  2. I Got ffmpeg command from Here
  3. I tried Few of more ffmpeg command .Please check it below.

  string strParam = "-y -stream_loop -1 -i " + image + ".jpg -i " + AudioFile + ".mp3 -y -r 25 -b 2500k - acodec ac3 - ab 384k - vcodec mpeg4 " + outputfile+".mp4";

  another one

  string strParam = "-loop 1 -i " + image + ".jpg -i " + AudioFile+ ".mp3 -c:v libx264 -tune stillimage -c:a aac -strict experimental -b:a 192k -pix_fmt yuv420p -shortest " + outputfile+".mp4";

• how can I get the length of an video in order to validate django form before upload can begin ?

  20 juin 2018, par GetItDone

  I have an app running on heroku that allows users to upload videos, then I use ffmpeg to preform 3 tasks using celery and redis-to-go :

  1) Check the format and if it isn't already mp4, convert it to mp4.
  
  2) Extract a 3 minute clip, in mp4 format
  
  3) Grab an image from the video

  The problem is that I want to verify the video length before the video is uploaded and the three tasks are run since I want to make sure all videos are at least 15 minutes, and if not I want to raise a ValidationError. So when validating the form, I want to do something like this :

  def clean(self, *args, **kwargs):        
  
      data = super(ContentTypeRestrictedVideoField, self).clean(*args, **kwargs)
  
  
  
      file = data.file
  
      try:
  
          content_type = file.content_type
  
          main, extension = content_type.split('/')
  
          if content_type in self.content_types:
  
              if file._size > self.max_upload_size:
  
                  raise forms.ValidationError(_('Please keep filesize under %s. Current filesize %s') % (filesizeformat(self.max_upload_size), filesizeformat(file._size)))
  
              if VIDEO_LENGTH < MINIMUM_LENGTH:
  
                  raise forms.ValidationError(_('Please make sure video file is at least %s. Current video length %s') % (MINIMUM_LENGTH, VIDEO_LENGTH)
  
          else:
  
              raise forms.ValidationError(_('File type is not supported. File must be mov, flv, avi, mpeg, wmv, or mp4.'))
  
      except AttributeError:
  
          pass        
  
  
  
      return data

  What could I do for VIDEO_LENGTH and MINIMUM_LENGTH ? I read that ffprobe could be used for getting the duration, but it isn’t available with the buildpack I am using and I am very inexperienced. I can’t just validate file size because it can vary greatly depending on numerous factors. Anyone have any solution as to what I could try ? Thanks

• GDPR compliance for Matomo’s Premium Features like Heatmaps & Session Recording, Form Analytics, Media Analytics & co

  27 avril 2018, par InnoCraft

  The General Data Protection Regulation (EU) 2016/679, also referred to as RGPD in French, Datenschutz-Grundverordnung, DS-GVO in German, is fast-approaching. It is now less than 30 days until GDPR applies to most businesses around the world on 25th May 2018. If you haven’t heard of this new regulation yet, I recommend you check out our GDPR guide which we continue to expand regularly to get you up to speed with it.

  GDPR compliance in Matomo

  We are currently adding several new features to Matomo to get you GDPR ready. You will have for example the possibility to delete and export data for data subjects, delete and anonymize previously tracked data, anonymize the IP address and location, ask for consent, and more. A beta version with these features is already available. We will release more blog posts and user guides about these features soon and just recently published a post on how to avoid collecting personal information in the first place soon.

  If you are still using Piwik, we highly recommend you update to a recent version of Matomo as all versions of Piwik will NOT be GDPR compliant.

  GDPR compliance for premium features

  InnoCraft, the company of the makers of Matomo, are offering various premium features for your self-hosted Matomo so you can be sure to make the right decisions and continuously grow your business. These features are also available on the cloud-hosted version of Matomo.

  If you are now wondering how GDPR applies to these features, you will be happy to hear that none of them collect any personal information except for possibly Heatmaps & Session Recording and the WooCommerce integration. All of them also support all the new upcoming GDPR features like the possibility to export and delete data. It is important that you update your Matomo Premium Features to the latest version to use these features.

  Making Heatmaps & Session Recording GDPR compliant

  We have added several new features to make it easy for you to be GDPR compliant and in many cases you might not even have to do anything. Some of the changes include :

  • Keystrokes (text entered into form fields) are no longer captured by default.
  • You may enable the capturing of keystrokes, and all keystrokes will be anonymized by default.
  • You may whitelist certain form fields to be recorded in plain text. However, fields that likely contain personal or sensitive information like passwords, phone numbers, addresses, credit card details, names, email addresses, and more will be always anonymized to protect user privacy. (this has always been the case but we have now included many more fields).

  How personal information may still be recorded

  Nevertheless, Heatmaps and Session Recordings may still record personal or sensitive information if you show them as part of the regular website as plain text (and not as part of a form field). The below example shows an email address for a paypal account as well as a name and VAT information as a regular content.

  

  To anonymize such information, simply add a data-matomo-mask attribute to your website :

  <span data-matomo-mask>example@example.com</span>

  You can read more about this in the developer guide “Masking content on your website”.

  WooCommerce Integration

  The WooCommerce integration may record an Order ID when a customer purchases something on your shop. As the Order ID is an identifier which could be linked with your shop to identify an individual, it may be considered as personal information. Matomo now offers an option to automatically anonymize this Order ID so it is no longer considered as personal information. To enable this feature, log in to your Matomo and go to “Administration => Anonymize Data”.

  GDPR compliance for third party plugins on the Matomo Marketplace

  The Matomo Marketplace currently features over 80 free plugins. Over 50 of them are compatible with the latest Matomo 3.X version and most of them should support Matomo’s new GDPR features out of the box. If you are concerned by GDPR and are not sure if a third party plugin stores any personal information, we highly recommend you ask the developer of this plugin about the compliance.

  You can find a link to the plugin’s issue tracker by going to a plugin page and then clicking on “Github” on the bottom right.

  

  If you are a plugin developer, please read our developer guide “GDPR & How do I make my Matomo plugin compliant”.
