2012-03-17mpegvideo: don't pretend the first frame is always a key frameWolfram Gloger
Signed-off-by: Wolfram Gloger <wmglo@dent.med.uni-muenchen.de> Modify the parser initialization so that parsers can set pict_type themselves. Use this in the mpegvideo parser so that initial frames are not unconditionally I frames. I have had this in my tree for several years. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

2009-03-02Favor container packets that end after the first byte of the accessMichael Niedermayer
unit in fetch_timestamp(). This should make no difference for valid streams but may help invalid ones, also its needed for future changes. Originally committed as revision 17732 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-03-02Call ff_fetch_timestamp() for mpeg1/2 when a picture start code is found insteadMichael Niedermayer
of calling it at the end of a frame with a large negative offset. This significantly reduces the maximal distance in container packets between the point where the first byte of the "access unit" was stored and where we call ff_fetch_timestamp() thus reducing the constraints on our parser. Also change the parser from next_frame_offset to cur, this is needed because now the reference is from container packet start instead of frame start.
