avcodec: set AV_CODEC_CAP_CHANNEL_CONF on decoders which set their own channels
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

avcodec/ilbcdec: Fix integer overflow in construct_vector()
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 overflows
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.
