Javan Whistling Duck Release Candidate

[Johann Koenig]

The VP9 encoder has matured and many improvements have been made to decoding performance.

The release will be ABI incompatible with 1.4.0. It removes the long deprecated controls VP8E_UPD_ENTROPY, VP8E_UPD_REFERENCE and VP8E_USE_REFERENCE. VP8 gains a new screen content mode. VP9 gains VP9E_GET_ACTIVE_MAP, VP9E_SET_RENDER_SIZE, VP9E_SET_COLOR_RANGE, VP9E_SET_[MIN|MAX]_GF_INTERVAL, and VP9_SET_SKIP_LOOP_FILTER.

Please test with your systems and let us know via the bug tracker[0] or mailing list[1] if you encounter any issues. We hope to finalize this release soon.

What's new?

 - The above codec controls

 - Substantially improved VP9 encoding speed and quality

 - Improvements to VP9 decode speed including algorithmic changes to the multi threaded decoder.

What's not in this release?

 - VP10. The vp10/ directory will be removed from the release branch.

 - While many improvements have been made for vp9 realtime encoding and many more are ongoing we encourage people interesting in this use-case to submit changes to the master branch.
