  • avcodec/smcenc : Move PutByteContext to stack

    avcodec/smcenc : Move PutByteContext to stack
    

    This context is transient, so putting it on the stack is more natural.
    Also reduces codesize : 24E6->2296 B with GCC 10 and -O3.

  • Fragmented mp4 file is not played by MSE

    19 mai 2020, par Daniel

    I created a fragmented mp4 file with ffmpeg (from h264), and removed the first 6 moof and mdat pairs.

    &#xA;&#xA;

    So now it still has the correct order of boxes : ftyp, moov, moof, mdat, moof, mdat, ..., but the first moof packet has the sequenceNumber of 7.

    &#xA;&#xA;

    VLC can play it fine, 'Movies & TV' can also play, but the first some seconds are black.

    &#xA;&#xA;

    If I drag the file into the browser, it can also play it fine.

    &#xA;&#xA;

    It is however not being displayed at all in the browser (Chrome) if I feed it via MSE.

    &#xA;&#xA;

    No error messages are printed, and in the media-internals' log it can be seen that the videoplayer starts playing in the first second and suspends it only in the 18th second :

    Here is the video file for reference.

    What is the problem with this file, why is it not displayed in the browser with MSE ?
