Hendrik Leppkes	83a940e7fb	h2645_parse: don't overread AnnexB NALs within an avc stream We know the maximum size of an AnnexB NAL, signaling it as the maximum NAL size allows ff_h2645_extract_rbsp to determine the correct size.	8 years ago
Hendrik Leppkes	c3e9b098e1	h2645_parse: only read avc length code at the correct position Reading it from any other position would result in a wrong size being read, instead fallback to the re-sync mechanic in the else clause.	8 years ago
Hendrik Leppkes	a9bb4cf87d	h2645_parse: support badly muxed mp4 streams Some streams contain an additional AnnexB NAL inside the mp4/nalff NALU. This commonly occurs in interlaced streams where both fields are packed into the same MP4 NAL with an AnnexB startcode in between. Port handling of this format from the previous h264 nal handling. Fixes trac #5529	9 years ago
Hendrik Leppkes	d46e856350	h265_parse: skip zero sized NAL units Avoids extra error checks later on and/or invalid reads. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	9 years ago
Hendrik Leppkes	9cc1ab63ac	h2645_parse: allow partial escaping This ports the fix from `033a533` to the new parser module in prepartion of using it for the h264 decoder. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	9 years ago
Hendrik Leppkes	c802389393	h2645_parse: initialize the GetBitContext to the proper size Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	9 years ago
Anton Khirnov	90ed6c5cf7	h2645_parse: compute the actual data length, without trailing paddding This is required by h264.	9 years ago
Anton Khirnov	b667252a41	h2645_parse: add support for parsing h264	9 years ago
Anton Khirnov	52ec149fbe	h2645_parse: change the AVCodecContext* parameter to void* This should make it more clear that it is not supposed to be used for anything except logging.	9 years ago
Anton Khirnov	8229eff4b7	h2645_parse: add a function for uninitializing the packet	9 years ago
Anton Khirnov	fa936a307f	hevc_parse: rename into h2645_parse This code will be shared with h264.	9 years ago
Mark Thompson	fbec157ea0	lavc/hevc: Allow arbitrary garbage in bytestream as long as at least one NAL unit is found. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Vittorio Giovara	059a934806	lavc: Consistently prefix input buffer defines Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
Michael Niedermayer	744051a57a	avcodec/hevc_parse: Print the name of the NAL units in addition to the numerical nal_unit_type in the debug output Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Michael Niedermayer	99558270ed	avcodec/hevc: Simplify skipped_bytes_pos code further Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Michael Niedermayer	ad92410d90	avcodec/hevc: Move skipped_bytes_pos_nal to HEVCNAL, simplify code Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Michael Niedermayer	bcc6c7bb65	avcodec/hevc: Move skipped_bytes_pos_size_nal into HAVCNAL Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Michael Niedermayer	5620ed3557	avcodec/hevc: Remove skipped_bytes_nal, simplify code Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Anton Khirnov	d82e1adc20	hevc: move splitting the packet into NALUs into a separate function This function is independent of the decoding context, so we'll be able to use it in the parser.	9 years ago
Anton Khirnov	69ab9f53f9	hevc: split bitstream unescaping to a separate file It will be useful in the QSV HEVC encoder.	9 years ago
