• ffmpeg video not working in JWPlayer

  20 août 2014, par shailesh gupta

  I have created a video from mixing an audio and a video. By using

   ffmpeg -i video.mp4 -i a.mp3  -vcodec copy -acodec copy -map 0.0 -map 1.0 -shortest output.mp4

  Its working fine in VLC player but no sound in JWPlayer. Its also buffering the whole video before starting the video.
  How to resolve this issue .

  Here is output of ffmpeg command.

• Conversion of .iva to .mp4 using ffmpeg

  9 juin 2016, par Rupesh Parab

  The video which I am trying to convert is uploaded at http://www.filedropper.com/video_17

  I am using the following command to convert the file :

  ffmpeg -i archive.iva -c copy -map 0 output.mp4 -vsync 2 -y;

  The file should be around 1 min in length but after conversion is of only 7 secs

  What am I doing wrong ?
