* avcodec/pnm: Check scaleMichael Niedermayer2020-06-08
| | | | | | | | Fixes: division by zero Fixes: 22974/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_PFM_fuzzer-6270027077779456 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* hevc: move SliceHeader and LongTermRPS back to hevcdec.hAnton Khirnov2020-06-08
| | | | | | | They are no longer necessary there and have nothing to do with parameter sets, so do not belong in hevc_ps.h. This effectively reverts 4aaace8b25.
* hevc_parser: drop the use of SliceHeaderAnton Khirnov2020-06-08
| | | | | It is only used to store a few local variables within one function, which is better accomplished by just declaring them on stack explicitly.
* hevc_refs: reduce code duplication in find_ref_idx()Anton Khirnov2020-06-08

* avcodec/v4l2_m2m_enc: Avoid ;;Andreas Rheinhardt2020-06-08
| | | | | | | | | | | | | Inside a function, the second ; in a double ;; is a null statement, but outside of functions a double ;; is simply invalid C that compilers happen to accept. v4l2_m2m_enc.c contained several ;; as a result of macro-expansion. So change the underlying macro so that it doesn't happen any longer. This fixes warnings when compiling with -pedantic: "ISO C does not allow extra ‘;’ outside of a function".

* libavcodec/jpeg2000_parser: Add jpeg2000 parserGautam Ramakrishnan2020-06-07
| | | | | | | | | | I have attempted to write a JPEG2000 Parser. Have tested by generating a file containing 14 frames, as mentioned by Micheal. Have also tried testing with various packet sizes by setting -frame_size option. Additionally, fixed a few formatting issues as pointed out by Micheal.

* avcodec: add constants for KLV pseudo-profile.Brad Hards2020-05-31
| | | | | | | | | | | | | | | | | There are two different ways KLV is used in MISB specs - sync and async. The corresponding text (in ST1401) says: ISO/IEC 13818-1 Table-34 defines a stream_type = 0x15 for “Metadata carried in PES packets,” and Table 2-22 defines a stream_id = 0xFC for “metadata stream.” and In ISO/IEC 13818-1, Table-34 defines a stream_type = 0x06 for “PES packets containing private data,” and Table 2-22 defines a stream_id = 0xBD for “private_stream_1.” These constants allow us to distinguish the two cases, as codec profiles.

* lavc/hevc_refs: Fix the logic of find_ref_idx()Xu Guangxin2020-05-27
| | | | | | | | | | | | | | | | | | | | | | | | | Currently find_ref_idx() would trigger 2 scans in DPB to find the requested POC: 1. Firstly, ignore MSB of ref->poc and search for the requested POC; 2. Secondly, compare the entire ref->poc with requested POC; For long term reference, we are able to only check LSB if MSB is not presented(e.g. delta_poc_msb_present_flag == 0). However, for short term reference, we should never ignore poc's MSB and it should be kind of bit-exact. (Details in 8.3.2) Otherwise this leads to decoding failures like: [hevc @ 0x5638f4328600] Error constructing the frame RPS. [hevc @ 0x5638f4328600] Error parsing NAL unit #2. [hevc @ 0x5638f4338a80] Could not find ref with POC 21 Error while decoding stream #0:0: Invalid data found when processing input Search the requested POC based on whether MSB is used, and avoid the 2-times scan for DPB buffer. This benefits both native HEVC decoder and integrated HW decoders. Signed-off-by: Xu Guangxin <guangxin.xu@intel.com> Signed-off-by: Linjie Fu <linjie.fu@intel.com>

| | | | | | | | | | | | | Including codecapi.h and uuids.h in UWP mode doesn't define all defines properly, ending up with constructs that MSVC silently tolerates, but that clang errors out on, like this: DEFINE_GUIDEX(CODECAPI_AVEncCommonFormatConstraint); Just avoid including codecapi.h completely and hardcode the last few enum values we use from there.
