Create a new RTCP feedback message for reporting the loss and/or non-decodability of video frames, to be used by the upcoming injectable VideoFrameBufferController. The new feedback message should report: 1. The sequence number of the last decoded non-discardable video frame. (TBD: If a multi-packet frame, should it be the sequence number of the first, last, or any of the packets?) 2. The sequence number of the last received RTP packet in the stream. 3. A decodability flag, whose specific meaning depends on the last-received RTP sequence number. The decodability flag is true if and only if all of the frame's dependencies are known to be decodable, and the frame itself is not yet known to be unassemblable. * Clarification #1: In a multi-packet frame, the first packet's dependencies are known, but it is not yet known whether all parts of the current frame will be received. * Clarification #2: In a multi-packet frame, the dependencies would be unknown if the first packet was not received. Then, the packet will be known-unassemblable.
