This is a reland of 47836b4ebb8a5c71695b5ec07bffd5ee4e3bc2ff Internal tests are synced with the fix. Original change's description: > Keep spatial_idx=kNoSpatialIdx(255) if there is no layer indices. > > spatial_idx is not present in RTP header if there is no temporal or > spatial layering. But the parser sets spatial_idx to 0 in this case. > When reflector repacketizes such packets it writes layering indices > into outgoing packets. When packets arrive to receiver it thinks that > it deals with multi layer stream and passes it through special path > in Vp9 reference frame finder which never outputs inter frames. > > I modified the parser such that it keeps spatial_idx=kNoSpatialIdx(255) > when there is no layer indices in RTP header. Related unit tests have > been modified as well. > > Bug: none > Change-Id: I14498cafb4e57797577dc873298c35b243479f88 > Reviewed-on: https://webrtc-review.googlesource.com/17980 > Commit-Queue: Sergey Silkin <ssilkin@webrtc.org> > Reviewed-by: Erik Språng <sprang@webrtc.org> > Reviewed-by: Åsa Persson <asapersson@webrtc.org> > Reviewed-by: Rasmus Brandt <brandtr@webrtc.org> > Cr-Commit-Position: refs/heads/master@{#20560} TBR=brandtr@webrtc.org,asapersson@webrtc.org,sprang@webrtc.org Bug: none Change-Id: I6087a8b20a926296b30432d69251670120b2a20c Reviewed-on: https://webrtc-review.googlesource.com/20940 Reviewed-by: Sergey Silkin <ssilkin@webrtc.org> Commit-Queue: Sergey Silkin <ssilkin@webrtc.org> Cr-Commit-Position: refs/heads/master@{#20591}
