Based on the discussion at the Virtual Interim, I have revised PR #9, which deals with the tx-mode SDP parameter. The proposed revision is as follows: tx-mode: Implementations SHOULD NOT include this parameter within SDP. If no tx-mode parameter is present, a value of "SRST" MUST be inferred. Support for the "MRST" and "MRMT" modes is OPTIONAL; implementations that do not support the "MRST" or "MRMT" modes MUST NOT include these modes in the tx-mode parameter. Review comments welcome: https://github.com/aboba/hevc-webrtc/pull/9
