  • How to play avi files on browser

    31 janvier 2017, par mvalencaa

    My team needs to develop a system that plays avi files on the web. These files are recorded by a hardware whose firmware we don’t have access to. We are trying to negotiate it with the manufacturer to change the file format to mp4, but until now we have nothing.

    Because of this, we are trying another manners to make it work. Our first attempt was to use FFMPEG to convert the files to mp4 (or webm or ogg), but this process takes too long because we have to do it everyday with a really huge amount of videos.

    We also tried to use FFMPEG’s copy command (which is much faster), but the video always crashes at some point (mainly when we need to navigate in its timeline) and we don’t know why.

    So now we are thinking to customize videojs flash player to reproduce the AVI files, but because we don’t have too much experience with video programming and flash, we don’t know if this is possible. Is it possible to write a decoder in action script to read avi files ?

    I saw that Youtube and Facebook can play AVI files... How do they do this ? I have already looked a lot about it, but had no success.

  • FFmpeg - Concat videos with different time base

    21 janvier 2017, par Xys

    I’m trying to concat videos with the concat demuxer, but it does not work when using one video ("video2.mp4" below). By does not work, I mean playing the concatenated video on a player will work until the second video part starts (it just cannot read the video anymore). It works with the concat filter though. They are both mp4 videos, so I think it’s because of the time base ? I can concat other videos with the concat demuxer and it works fine (even with different resolutions/bitrate). It only happens when trying to concat "video2.mp4".

    Also, I have a lot of warning/errors like this, probably when ffmpeg starts concatenating the 2nd video :

    [mp4 @ 0x7f847a814800] Non-monotonous DTS in output stream 0:0; previous: 906906, current: 302359; changing to 906907. This may result in incorrect timestamps in the output file.

    What would be the best way to have a minimum concat time ? Do I really need to use the concat filter or can I change the time base of "video1.mp4" if it’s really the problem ?

    Any help would be appreciated, thanks !

  • ffmpeg mkv to mp4 including subtitles

    1er février 2017, par user3677559

    Want to convert mkv files to mp4 (h264, mp3 and subtitles). I checked the video files with ffprobe. For the output

    Stream #0:2(ger) : Subtitle : dvb_subtitle (default)

    The subtitles are included in the converted video with following ffmpeg command.

    ffmpeg -i movie.mkv -c:v libx264 -c:a libmp3lame  -b:a 320k -c:s dvd_subtitle  converted.mp4

    But for the output :

    Stream #0:3(ger) : Subtitle : subrip (default)

    The command isn’t working. There is no error message and the resulting video includes a subtitle stream, but no subtitles are showed. I tried also with the subtitle encoding mov_text and copy, but no luck. Following the output from console :
