eb90a2091f pthread: Fix deadlock during thread initialization 
Sometimes, if pthread_create() failed, then pthread_cond_wait() could
accidentally be called in the worker threads after the uninit function
had already called pthread_cond_broadcast(), leading to a deadlock.

Don't call pthread_cond_wait() if c->done is set.

41a10f3ba1 vp6: Support cropping to AVCodecContext.width/height 
In these cases, there is no extradata but only the properly set
width/height values by the demuxer.

This makes sure VP6 in F4V files is cropped properly.

This is similar to what is done for H264 for letting the container
width/height override what's in the bitstream, since 30f515091.
