* Revert "lavf/mp3dec: don't adjust start time; packets are not adjusted."Michael Niedermayer2020-06-082-1/+5
| | | | | | | | | This causes regressions in end to end timestamps with mp3s and ffmpeg. The revert is to avoid this regression in the 4.3 release See: [FFmpeg-devel] [PATCH] Don't adjust start time for MP3 files; packets are not adjusted. This reverts commit 460132c9980f8a1f501a1f69477bca49e1641233.
* avcodec/mpeg12dec: Fix got_outputMichael Niedermayer2020-06-081-1/+1
| | | | | | | | | | | | | | | | This makes got_output consistent with the code in slice_end() which sets the output in slice_end() if (s->pict_type == AV_PICTURE_TYPE_B || s->low_delay) { int ret = av_frame_ref(pict, s->current_picture_ptr->f); ... } else { Fixes: assertion failure Fixes: 22178/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_MPEG1VIDEO_fuzzer-5664234440753152 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* avcodec/hcadec: Check or bound indexesMichael Niedermayer2020-06-081-2/+2
| | | | | | | | | | | | | This causes indexes into scale_conversion_table to wrap around, alternatively they could be clipped, the table be enlarged or we can error out.

* hevc: move SliceHeader and LongTermRPS back to hevcdec.hAnton Khirnov2020-06-082-84/+84
| | | | | | | 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 Khirnov2020-06-081-27/+30
| | | | | It is only used to store a few local variables within one function, which is better accomplished by just declaring them on stack explicitly.

* avcodec/v4l2_m2m_enc: Avoid ;;Andreas Rheinhardt2020-06-081-1/+1
| | | | | | | | | | | | | 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".
