| * parsers: initialize MpegEncContext.slice_context_count to 1Janne Grunau2012-01-06
| | | | | | | | | | | | | | | | | | The mpeg4 video, H264 and VC-1 parser hold (directly or indirectly) a MpegEncContext in their private context. Since they do not call the common mpegvideo init function slice_context_count has explicitly set to 1. Prevents a null pointer dereference in the h264 parser and fixes bug 193.
| * Revert "h264: skip start code search if the size of the nal unit is known"Janne Grunau2011-12-19
| | | | | | | | This reverts commit 87eebb3454ff0cd6af6ebf9e1d31bdfd1c3b601b.
| * h264: skip start code search if the size of the nal unit is knownJanne Grunau2011-12-18
| | | | | | | | | | | | | | | | Start code emulation prevention is only required in Annex B bytestream packed NAL units. For other coding formats the size is already known. Looking for a start code prefix can result in false positives like in http://streams.videolan.org/streams/mp4/Mr_MrsSmith-h264_aac.mp4 which has a false positive in the SPS.

* | Fix parser not to clobber has_b_frames when extradata is set.Reimar Döffinger2011-08-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to it in contrast to the decoder not setting up low_delay, the code in parse_nal_units would always end up setting has_b_frames to 1 (except when stream is explicitly marked as low delay). Since the parser itself would create extradata, simply reopening the parser would cause this. estimate_timings_from_pts would cause the parser to be reopened on the same stream. This fixes trac issue #360. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>
