Callback set by HardwareVideoEncoder, and wired to the codec's releaseOutputBuffer. Intention is to move call of this method to the destructor of a corresponding C++ class in a followup cl, and eliminate an allocation and memcpy in the process. Bug: webrtc:9378 Change-Id: I578480b63b68e6ac7a96cdde36379b3c50f05c3f Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/142160 Commit-Queue: Niels Moller <nisse@webrtc.org> Reviewed-by: Sami Kalliomäki <sakal@webrtc.org> Cr-Commit-Position: refs/heads/master@{#29283}
