  • mov : Disable advanced_editlist for fragmented MP4 input

    28 décembre 2022, par Derek Buitenhuis
    mov : Disable advanced_editlist for fragmented MP4 input
    

    Advanced edit list support is entirely broken for fragmented MP4s,
    currently. mov_fix_index is never run in mov_build_index, since
    in fragmented MP4s the stco, stsz, stts, and stsc boxes have zero
    entries, with the index being filled in as each fragment's trun
    box is seen.

    The result of this is that the skip samples is never set properly,
    since half the code thinks it doesn't need to, as advanced_editlist
    is enabled, but as mov_fix_index is never called, it doesnt get set.
    This means that any edits for e.g. priming are not properly applied
    as skip samples side data.

    This also means remuxing to fragmented MP4 from progressive MP4 with
    lavf will quietly drop the edit list, currently.

    Example :

    $ ffmpeg -loglevel quiet -advanced_editlist 1 -i non_fragmented.mp4 -f md5 -
    MD5=d02d929f8eb4edef624758a298d5f7c6
    $ ffmpeg -loglevel quiet -advanced_editlist 0 -i non_fragmented.mp4 -f md5 -
    MD5=d02d929f8eb4edef624758a298d5f7c6
    $ ffmpeg -loglevel quiet -advanced_editlist 1 -i fragmented.mp4 -f md5 -
    MD5=e38b110f586fa886ff94e0ca98a95d59 <— wrong, extra samples are output instead of being skipped
    $ ffmpeg -loglevel quiet -advanced_editlist 0 -i fragmented.mp4 -f md5 -
    MD5=d02d929f8eb4edef624758a298d5f7c6

    We cannot call mov_fix_index after reading a trun box
    since mov_fix_index seems to assume it is only called once, on a
    fully complete index, an multiple calls to it don't seem like
    they'd work, so the "best" option seems to be disabling advanced
    edit list support entirely for the time being, as it is broken
    for these types of files.

    • [DH] libavformat/mov.c
  • Find video resolution and video duration of remote mediafile

    22 février 2012, par osgx

    I want to write an program which can find some metainformation of mediafile. I'm interested in popular video formats, such as avi, mkv, mp4, mov (may be other popular too). I want basically to get :

    • Video size (720, 1080, 360 etc)
    • Total runtime of video (may be not very exact)
    • Number of audio streams
    • Name of video codec
    • Name of audio codec

    There is already the mediainfo, but in my program I want to get information about remote file, which may be accessed via ftp, http, samba ; or even torrent (there are some torrent solutions, which allows to read not-yet downloaded file).

    MediaInfo library have no support of samba (smb ://) and mkv format (for runtime).

    Also, I want to know, how much data should be downloaded to get this information. I want not to download full videofile because I have no enough disk space.

    Is this information in the first 1 or 10 or 100 KiloBytes of the file ? Is it at predictable offset if I know the container name and total file size ?

    PS : Platform is Linux, Language is C/C++
