[FFmpeg-devel] [PATCH 1/3] avcodec/mlpenc: remove delay codec capability

[James Almer]

The encoder has no delayed packets at the end of the encoding
process, so signaling this capability is unnecessary.

This also fix an assertion failure introduced in 827d6fe73d, as
return values higher than 0 are not expected.
