Henrik Boström 3889de1c4c Support native scaling of VideoFrameBuffers in LibvpxVp8Encoder. ... This is a follow-up to the VP9, fixing VP8 this time. Context again: This CL is part of Optimized Scaling efforts. In Chromium, the native frame buffer is getting an optimized CropAndScale() implementation. To support HW accelerated scaling, returning pre-scaled images and skipping unnecessary intermediate downscales, WebRTC needs to 1) use CropAndScale instead of libyuv::XXXXScale and 2) only map buffers it actually intends to encode. - To achieve this, WebRTC encoders are updated to map kNative video buffers so that in a follow-up CL VideoStreamEncoder can stop mapping intermediate buffer sizes.
