• CDN do not allow me to convert mov video format to mp4

  16 avril 2021, par Azzo

  I have tried so many thinks on stackoverflow but didn't fix my issue. So I am using following code for converting mov video format to mp4 video format. The code is working fine if I disable CDN but when I enable CDN then ffmpeg didn't work. What is wrong with CDN with the code below ?

  


  $cmd = shell_exec("ffmpeg -i video.mov -vcodec copy -acodec copy video.mp4");


  


  Command :

• App Preview, how to add blank audio track in iMovie ? or ffmpeg ?

  2 mars 2017, par toast

  Apple (customer support) is telling me that I must have audio in my app preview.

  My question is, how do I add a blank audio track to my mp4 app preview file ?

  Or is there some other way I can get my app preview approved without having audio ?

  There are many reasons why I dont want audio in my app preview. 1) I dont want to add some weird music in there thats not copyrighted. 2) I’m not going to narrate my app.

• cutting mp4 with codec copy results no audio in browser

  16 novembre 2020, par Luka

  I'm editing a video clip with ffmpeg. The original does not play in Firefox browser by itself. It does normally in Chromium. I do something like :

  


  ffmpeg -ss 00:05:10 -i INPUT.mp4 -c copy OUTPUT.mp4


  


  the resulting clip plays in Firefox but there's no audio. This happens in Firefox (82.0.3), but not in Chromium (86.0.4240.75). In chromium the sound is ok.

  


  If audio is reencoded with

  


  ffmpeg -ss 00:05:10 -i INPUT.mp4 -c:v copy -ab 360kb OUTPUT.mp4


  


  resulting clip is playing ok in Firefox.

  


  Could anyone explain what is happening here and is it possible to cut the mp4 without reencoding audio resulting in a clip that plays in Firefox too ?

  EDIT :

  


  I'm providing links to original files, but a bit of warning, they are 4-5GB big each :

  


  

  1. original recording from blackmagic switcher/capture/recorder (this does not play in firefox at all, but does in Chromium)

  


  2. cut version made with -codec copy (plays in firefox but no audio. plays in chromium ok)

  


  3. cut version with re-encoded audio (plays ok in both firefox and chromium)
