   Cannot run program "/data/user/0/com.example.mytestapp/files/ffmpeg": error=13, Permission denied


  


  Dependency I am using

  


   implementation 'com.writingminds:FFmpegAndroid:0.3.2'


  


  I am using following code to merge an audio into the video. I added the dependency and provided the path of the video. I also placed the ffpmeg.exe into the assets folder

• Suggestion query : Someone should add 'percent-complete' to ffmpeg's status line

  19 février 2018, par Dave

  I use the PC-platform’s ffmpeg (on Windows and Linux). I’ve always
  wondered why, down on that bottom dynamic status line, it does NOT
  show a ’percent-complete’ value.

  e.g. There’s already a line showing what time-line value is being worked
  on, so I’d expect it would be straight-forward to grab total duration, compute percent-complete, and show it, right after the running time value. Or,
  if based on frames, then show it in parentheses after the frame value.

  The reason I think it would be straight-forward is because I see it
  discussed in detail, for ffmpeg on Android, here :
  How to add progress bar to FFMPEG android
  and it talks about time-values and frame-count based calculations.

  Any volunteers to tackle this ? ^ ;)

• using default poster image with video and audio tags

  23 décembre 2016, par Ravinder Payal

  I have a web-application where users can share music and videos ( will be saved on sme-server utilized by Web-Application ) and as we know some audio /video files have posters/thumbnails included/attached with them.
  NOW, I want to show those posters with audio or video in HTML5.
  I know about poster tag, but it needs a separate image file to show. However, I want to show image file attached with song (audio / video).
  Any suggestion related any java-script or HTML api will be appreciated.
  I know about obtaining poster images with ff-mpeg(or similar libraries), but that will add an extra work load on my server. Thanks.

  Note :-I may consider any server side efficient solution alo.

  Thanks in advance.
