Failed to process corrupted aac audio in ffmpeg 5.1

[ivyabc]

Summary of the bug:

ffmpeg 5.1.2 fails to skip corrupted aac audio and continue to process good data. git bisect points to this commit:

​https://github.com/FFmpeg/FFmpeg/commit/494760f971a41851630d7940abe914cd1115737e

The corrupted file is uploaded to streams.videolan.org

How to reproduce:

ffmpeg -i d04f47da-4a09-4a47-a56a-2d458b9a2c1b.m4a -f null /dev/null

ffmpeg 5.0:

The input file 17:51-23:46 is corrupted. ffmpeg prints error but can continue to process good data.

ffmpeg 5.1:

[auto_aresample_0 @ 0x56039de0dd40] [SWR @ 0x56039cb4a340] Rematrix is needed between 30 channels and stereo but there is not enough information to do it
[auto_aresample_0 @ 0x56039de0dd40] Failed to configure output pad on auto_aresample_0
Error reinitializing filters!
Failed to inject frame into filter network: Invalid argument
Error while processing the decoded data for stream #0:0
Conversion failed!

ffmpeg -i d04f47da-4a09-4a47-a56a-2d458b9a2c1b.m4a -vn -c:a aac -b:a 128k -ac 2 audio.m4a

Expected: 17:51-23:46 has no sound. Sound continues after 23:46.
Actual: Fails at 17:51

17:51 indeed.

aac: SBR was found before the first channel element.

ffplay.exe -acodec libfdk_aac

allows to play at 1406 seconds, i.e. 23:26, while -ss 23:25 already gives some warnings.

It appears after some time it fails (see no "stereo" word, another bug)

Maybe the reason is that fix that allowed 48 channel decoding ced6a5affb0ab1a24278b9bade76c36b8636e267
