2018-08-11vp9-svc: Fix to updated SET_SVC_REF_FRAME_CONFIG controlMarco Paniconi
Add flag to separate two cases of bypass (flexible) SVC mode: usage of using the SET_SVC_REF_FRAME_CONFIG vs passing in the frame_flags in the vpx_encode (only used for temporal layers). This fixes failures in Datarate Temporal layer test, introduced in commit: a66da31 Change-Id: Ie62f933987c20792d1f963d645e98c1903bdd423

2017-11-20[CFI] Remove function pointer castsVlad Tsyrklevich

2017-02-15Merge "Row based multi-threading of encoding stage"Yunqing Wang
2017-02-15Row based multi-threading of encoding stageRanjit Kumar Tulabandu
(Yunqing Wang) This patch implements the row-based multi-threading within tiles in the encoding pass, and substantially speeds up the multi-threaded encoder in VP9. Speed tests at speed 1 on STDHD(using 4 tiles) set show that the average speedups of the encoding pass(second pass in the 2-pass encoding) is 7% while using 2 threads, 16% while using 4 threads, 85% while using 8 threads, and 116% while using 16 threads.

2015-09-25Rename display_{size,width,height} to render_*.Ronald S. Bultje
The name "display_*" (or "d_*") is used for non-compatible information (that is, the cropped frame dimensions in pixels, as opposed to the intended screen rendering surface size). Therefore, continuing to use display_* would be confusing to end users. Instead, rename the field to render_*, so that struct vpx_image can include it.

2015-09-16Add support for color-range.Ronald S. Bultje
