[FFmpeg-devel] [PATCH v2 10/10] lavc/decode: do not perform decoding when sending draining packets

[Anton Khirnov]

This way decoding errors will not be returned when the user starts
draining the decoder, avoiding confusion over whether draining did or
did not start.

Fixes failures of fate-h264-attachment-631 for certain numbers of frame
threads (e.g. 5).
