* avcodec/hevc_ps: Fix integer overflow with num_tile_rows and num_tile_columnsMichael Niedermayer2019-06-301-2/+2
| | | | | | | | | Fixes: signed integer overflow: -2147483648 - 1 cannot be represented in type 'int' Fixes: 14880/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_HEVC_fuzzer-5130977304641536 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg Reviewed-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* avcodec/hevc_ps: Expose all SPS and PPS range extension flagsPhilip Langdale2019-02-161-0/+4
| | | | | | | We need all the flags to be exposed to be able to pass them on to HW decoders. I did not attempt to nuance any of the warnings about flags being unsupported as there's no way, at the point we extract flags, to say whether an HW decoder is being used.

* hevc: Improve stream constraint values in common headerMark Thompson2017-10-171-3/+3
| | | | | | | | | | Add comments to describe the sources of the constraint values expressed here, and add some more related values which will be used in following patches. Fix the incorrect values for SPS and PPS count (they are not the same as those used for H.264), and remove HEVC_MAX_CU_SIZE because it is not used anywhere. (cherry picked from commit b88da98b34809dedf8882d43ed543632ed233538)

* hevcdec: move parameter set parsing into a separate headerAnton Khirnov2016-10-161-0/+320
This code is independent from the decoder, so it makes more sense for it to to have its own header.
