• SOLVED - AVI to MP4 - ffmpeg conversion

  26 mai 2014, par Emmanuel Brunet

  I’m running a debian 7.5 machine with ffmpeg-2.2 installed following these instructions

  Issue

  I’m trying to display a mp4 video inside my browser. The original file has an AVI container format. I can successfully convert it to mp4 and the targetfile is readable (video + sound) with the totem movie player. So I thought everything would be OK displaying the bellow page

  HTML5 web page

      
  
  
  
  
  
  <video width="640" height="480" controls="controls">
  
    <source src="/path/to/output.mp4" type="video/mp4">
  
  <h3>Your browser does not support the video tag</h3>
  
  </source></video>

  Input probe

  $ ffprobe -show_streams input.avi
  
  
  
    Duration: 00:08:22.90, start: 0.000000, bitrate: 1943 kb/s
  
      Stream #0:0: Audio: mp3 (U[0][0][0] / 0x0055), 48000 Hz, stereo, s16p, 64 kb/s
  
      Stream #0:1: Video: mpeg4 (Advanced Simple Profile) (XVID / 0x44495658), yuv420p, 720x540 [SAR 1:1 DAR 4:3], 1870 kb/s, 29.97 fps, 25 tbr, 29.97 tbn, 25 tbc

  Convert

  $ ffmpeg -y -fflags +genpts -i input.avi -acodec copy -vcodec copy ouput.mp4

  Html browser

  Opening the above html file plays sound but no video is displayed.

  When I use other .mp4 files, videos succesfully displayed so I’m sure I face a conversion issue.

  Not : I’ve tryed a lot of other ffmpeg options but without success.

  Any idea ?

  Thanks in advance.

• Files conflict(lib/arm64-v8a/libc++_shared.so) with Jitsi and FFmpegKit

  15 mai 2022, par Riccoh

  I have a persistent problem that I can't seem to solve, I am using Android SDK 32 and have installed 2 Libraries(com.arthenica:ffmpeg-kit-full and org.jitsi.react:jitsi-meet-sdk) which are in conflict with one another.

  


  When I add these 2 libraries and tried to run it on my device I get the following error message "2 files found with path 'lib/arm64-v8a/libc++_shared.so' from inputs...".

  


  To solve this problem I applied the following solution : https://github.com/tanersener/ffmpeg-kit/wiki/Tips#2-depending-another-android-library-containing-libc_sharedso.

  


  This seems to work as my project runs succesfully on my device.
But when I am trying to call a ffmpeg command :

  


  FFmpegKit.execute("-y -i ${audioFile?.absoluteFile.toString()} -af asetrate=54100*1/2,atempo=2/1 ${audioVoice?.absoluteFile.toString()}")


  


  I get the following error..

  


  java.lang.Error: FFmpegKit failed to start on brand: google, model: Pixel 3, device: blueline, api level: 32, abis: arm64-v8a armeabi-v7a armeabi, 32bit abis: armeabi-v7a armeabi, 64bit abis: arm64-v8a.


  


  I searched further but couldn't find a solution to my problem.

  


  Is it possible to get both libraries working without issues ?

  Hi I am trying to compile ffmpeg but this error shows :

  If you think configure made a mistake, make sure you are using the latest
  
  version from Git.  If the latest version fails, report the problem to the
  
  ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
  
  Include the log file "config.log" produced by configure as this will help
  
  solving the problem.

  I am simply following this compilation guide : https://trac.ffmpeg.org/wiki/MacOSXCompilationGuide
