| * h2645_parse: handle embedded Annex B NAL units in size prefixed NAL unitsJanne Grunau2016-07-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes a regression in ca2f19b9cc3 with some mov/mp4 files. The files have several NAL units in the supposed single NAL unit after the size field. Annex B start code prefixes are used to separate them. The first NAL unit is correctly parsed but the buffer does not point to the next size field. Instead semi random data (it seems to be the rbsp_stop_one_bit and the start code prefix) is then parsed as length and will exceed the remaining length of the buffer. Patch based on the code in h264's decode_nal_units() and a similar patch by Hendrik Leppkes in FFmpeg (a9bb4cf87d1). Bug-Id: ffmpeg/trac5529 Reported-By: Vittorio Giovara

* | h2645_parse: don't overread AnnexB NALs within an avc streamHendrik Leppkes2016-07-08
| | | | | | | | | | 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.
* | h2645_parse: only read avc length code at the correct positionHendrik Leppkes2016-07-08
| | | | | | | | | | 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.
* | h2645_parse: support badly muxed mp4 streamsHendrik Leppkes2016-05-17
| | | | | | | | | | | | | | | | | | | | 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
* | h265_parse: skip zero sized NAL unitsHendrik Leppkes2016-05-07
| | | | | | | | | | | | Avoids extra error checks later on and/or invalid reads. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
* | h2645_parse: allow partial escapingHendrik Leppkes2016-05-07
| | | | | | | | | | | | | | 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>
