[FFmpeg-devel] [PATCH] avcodec/pthread_frame: Remove nonsense error message

[Andreas Rheinhardt]

If a frame-threaded decoder with inter-frame dependencies
returns an error when decoding a frame and the returned frame
isn't clean, an error message is emitted claiming that this
is a bug. This seems to be based upon the thinking that
in this case a ThreadFrame has not been properly unreferenced.
Yet this is wrong, as decoders with inter-frame dependencies
don't use the frame for output for synchronization and therefore
don't use ThreadFrames at all for this. So unreferencing
this frame generically is fine and not a bug.

I hope my guess of the rationale for this message was correct;
apologies if not.
