* avcodec: Constify AVCodecsAndreas Rheinhardt2021-04-27
| | | | | | | | | | Given that the AVCodec.next pointer has now been removed, most of the AVCodecs are not modified at all any more and can therefore be made const (as this patch does); the only exceptions are the very few codecs for external libraries that have a init_static_data callback.

* lavu/mem: move the DECLARE_ALIGNED macro family to mem_internal on next+1 bumpAnton Khirnov2021-01-01
| | | | They are not properly namespaced and not intended for public use.
* avcodec/hcadec: Check total_band_count against imdct_in sizeMichael Niedermayer2020-07-02
| | | | | | | | Fixes: index 128 out of bounds for type 'float [128]' Fixes: 23465/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_HCA_fuzzer-5089866596745216 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: get intensity from correct channelsummertriangle.dev@gmail.com2020-06-21
| | | | | | | Fixes an issue with one output channel being slightly louder than the other. The output now matches other public HCA decoders. Signed-off-by: t <summertriangle.dev@gmail.com>
* avcodec/hcadec: fix decoding of hfr channelssummertriangle.dev@gmail.com2020-06-21
| | | | | | | | I suspect this was originally broken by b7e5c8f , but even then, it only worked because it read out of bounds from intensity_ratio_table. Signed-off-by: t <summertriangle.dev@gmail.com>
* avcodec/hcadec: Check or bound indexesMichael Niedermayer2020-06-08
| | | | | | | | | | | | | This causes indexes into scale_conversion_table to wrap around, alternatively they could be clipped, the table be enlarged or we can error out. I have not found a document that specifies what is the correct way to handle this Fixes: out of array access Fixes: 21727/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_HCA_fuzzer-5752477891952640.fuzz Fixes: 22438/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_HCA_fuzzer-5640717790871552 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
