  • Playing large AVI files online with subtitles

    3 mai 2012, par Tareq

    I need a way to play a relatively large avi files (1+ GB) on the web with their subtitles, I have searched a lot for this, the only thing that I came up with was a normal embed without controls and it requires specific browser or application to show controls or even play.

    I have a large number of files (12 TB) so converting these files to mp4 would take ages not to mention having to miss with quality of audio or video.

    Is there a way that allows me to play these online along with their subtitls or should I convert these to MP4 ? I have tried to convert a file to MP4 and it didn't play either apparently it hits the browser limits or something (I tried playing it using flowplayer).

    I was considering a solution like red5, but as I found out it doesn't support avi either.

    I used this command to convert the mp4

    ffmpeg -y -i $file.avi -vcodec copy -acodec copy -copyts -f mp4 $file.mp4

    It toke relatively long time to get converted, if you have a better command or a solution that will work for playing the avis without converting, Please be my guest.

  • FFmpeg : Read profile level information from mp4

    I have a mp4 file and need the profile level of it. FFmpeg says, it has baseline profile, which is what I need, but I need also the level.

    Here is what I get from FFmpeg :

    Is there any option other than -i I can use to get the level information ?
