* vp9: re-split the decoder/format/dsp interface header files.Ronald S. Bultje2017-03-281-1/+1
| | | | | The advantage here is that the internal software decoder interface is not exposed to the DSP functions or the hardware accelerations.
* lavc/vp9: split into vp9{block,data,mvs}Clément Bœsch2017-03-271-1/+1
| | | | This is following Libav layout to ease merges.
* vp9dsp: Deduplicate the subpel filtersMartin Storsjö2016-11-151-59/+4
| | | | | | | | | Make them aligned, to allow efficient access to them from simd. This is an adapted cherry-pick from libav commit a4cfcddcb0f76e837d5abc06840c2b26c0e8aefc. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
