In Chromium, the I420ABufferInterface implementation uses the default CropAndScale() implementation which converts to I420 in the process. This should be OK, because we do not encode the alpha channel anyway, so having WebRTC scaling ignore the alpha channel might even be a good thing. Unfortunatety, an if statement in the LibvpxVp8Encoder did not consider I420A and I420 to be the same, resulting in dropping perfectly valid frames. This CL fixes that by considering I420A and I420 "compatible" in a comparison helper function. The problem only happens in this encoder, so only this encoder needs to be fixed.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.
Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.
The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.
