    And the above error repeats over and over again. The video completes and it is the right size and duration, it just plays the first video and then stops.

  • How do I create a streamable and seekable MP4 ? [migrated]

    21 mai 2013, par user492922

    I want to create an MP4 that supports seeking and streaming. DASH appears to be what I want except that the segment seek points are stored in an external file (the MPD) which doesn't work for my application ; I need seek metadata to be contained in the MP4.

    The next closest thing seems to be fragmented MP4s with the mfra box. I think this would work but it doesn't seem well supported (mplayer and totem fail to seek, recent ffplay works). Although the primary application is streaming (with the ability to seek) I would be reluctant to give up the ability to play the video from file on "standard" players.

    Is there any way I can make an MP4 that is streamable, seekable and plays within standard video players ?

    If I forgo the ability to play on standard video players is mfra the best way to go ?

    edit : By streaming I mean HTTP progressive download.

  • Convert MPEG4 to MPEGTS on Android with FFmpeg

    3 juin 2013, par Ardoramor

    Ok, so obviously I know very little to none about ffmpeg API when I made the original post... it is quite overwhelming when one starts learning about digital media and conversion details. After reading quite a bit more and going through ffmpeg source, I was able to get a working output from mp4 to mpegts. The concept is similar to executing :

    ffmpeg -i in.mp4 -vcodec copy -acodec copy -vbsf h264_mp4toannexb out.ts

    But as I mentioned before, I need to implement it with ffmpeg API in C.

    So, although I am able to generate a playable .ts file, its video and audio streams are not synced. That is, playing them back on Android tablet plays the video very slowly while audio is playing at normal speed and then (once audio stream ends) video plays at normal speed to the end. Playing the same generated .ts file in VLC produces a very condensed audio (as though fast-forwarded) and plays video fine.

    There are still many aspects of media conversion that I am not familiar with. I am sure that some of them prevent me from successful conversion.

    Here is some information (via ffprobe) about the files :
    - in.mp4 - file generated via Android recording - MPEG4 (H.264 + AAC)
    - ffmpeg.ts - file generated via ffmpeg conversion - MPEG2TS (H.264 + AAC)
    - out.ts - file generated via my code - MPEGTS (H.264 + AAC)

    As you can see, ffmpeg.ts starts out with video packets that do not have pts/dts. The audio packets that follow contain pts/dts. This repeats until the end. All video packets do not have pts/dts according to ffprobe output.

    However, out.ts starts with audio packets and alternate with video packets. Here, video packets also do not have pts/dts. The difference is that here there is one video packet between a series of audio packets. What happened to the rest of the video packets (ffmpeg.ts has 5 audio followed by 5 video).

    Obviously, I'm still learning and don't know way too much yet... Does anything jump out as obvious a problem to anyone ? I will greatly appreciate any info / suggestions but will continue to grind at it !!
