This change improves the performance and multicore
scalability of the vp9 codec for streaming single-pass encoded videos. The
current thread limit for ffmpeg codecs is 16 (MAX_AUTO_THREADS in

When writing a subtitle SSA/ASS subtitle file, the
AVCodecParameters::extradata buffer is written directly to the output,
including the null terminating character of the buffer. This appears to
be a simple off by one bug, which is fixed by the subsequent patch.
