Remove support for setting one limit without another limit because related rtp header extension doesn't support such values. Start morphing VideoPlayouDelay into a class and stricter type: add accessors returning TimeDelta Bug: webrtc:13756 Change-Id: If0dd02620528dc870b015beeff3a8103e04022ee Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/315921 Commit-Queue: Danil Chapovalov <danilchap@webrtc.org> Reviewed-by: Philip Eliasson <philipel@webrtc.org> Cr-Commit-Position: refs/heads/main@{#40570}
