Remove EncodedFrameContainer and clean up areas where it was used. EncodedFrameContainer provided a wrapper around an nsTArray<RefPtr<EncodedFrame>>, but it simplifies the code to simply expose this array. Also clean up unused enums in EncodedFrame, and clean up some of the outdated comments for our encoded frame handling. Differential Revision: https://phabricator.services.mozilla.com/D35384 --HG-- rename : dom/media/encoder/EncodedFrameContainer.h => dom/media/encoder/EncodedFrame.h extra : moz-landing-system : lando
