[FFmpeg-devel] [PATCH] avutil/channel_layout: don't error out on truncated strings

[James Almer]

The doxy for av_channel_layout_describe() states that the user should look
at the return value to check if the string was truncated. Returning an error
code in this scenario goes against this and is an API break.

This is a better fix than the one committed in 8154cb7c2f for the timeout
fuzzing issue.
