* avcodec/avcodec: Stop including channel_layout.h in avcodec.hAndreas Rheinhardt2021-07-22
| | | | | | Also include channel_layout.h directly wherever used. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/ilbcdec: Mark decoder as init-threadsafeAndreas Rheinhardt2021-05-02
| | | | Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* 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.

* avcodec: set AV_CODEC_CAP_CHANNEL_CONF on decoders which set their own channelsHendrik Leppkes2020-12-10
| | | | | | | | | | | | The decoders in this set either have a fixed channel count, or read it from the bitstream, and thus do not require the channel count as external information. Fixes various regressions since 81503ac58a763a36b1f57264013b1e76acb62b68, which requires a valid channel count for decoders which do not set this capability.

* avcodec/ilbcdec: Fix integer overflow in construct_vector()Michael Niedermayer2019-01-28
| | | | | | | | | | webrtc contains explicit code to ignore the undefined behavior (RTC_NO_SANITIZE / OverflowingAddS32S32ToS32()) Probably fixes: Integer overflow (unreproducable here) Probably fixes: 12215/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_ILBC_fuzzer-5767142427852800 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* avcodec/ilbcdec: Fix multiple integer overflowsMichael Niedermayer2018-10-18
| | | | | | | | | | | | | Fixes: 10651/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_ILBC_fuzzer-5202341540659200 Fixes: signed integer overflow: -1707705920 - 1703592888 cannot be represented in type 'int' This tries to follow the webrtc code. For example using cliping and 64 bit as in WebRtcSpl_DotProductWithScale() and not doing so in other places. I could not find anything in rfc3951 and the reference code inside which would explain what to do in these corner cases.
