Description Arnaud Vrac 2015-01-09 18:13:59 UTC
In push mode, seeking can result in EOS instead of prerolling and playing. This happens with this file:

This is a podcast with embedded covers, so the video frames are very sparse. In push mode I guess the best thing to do would be to send a GAP event until the next frame.

BTW this also happens with the 1.4 branch

    qtdemux: do not use sparse streams in push-based seeking
    Using the sparse streams can make the push-based seeking return
    too far in the stream. It also can lead to issues as the
    sparse streams will be ignored when restarting playback and,
     if the sparse stream is the one that has the earliest sample,
    it will confuse qtdemux's offsets as one stream will have
    an earlier offset than the demuxer's one which might lead to
    early EOS.
