This reverts commit bbdabe50db0cf09f6007dda12a6476dc4602b174. Reason for revert: This breaks the internal build. Original change's description: > Rename stereo video codec to multiplex > > This CL only does the rename from"stereo" to multiplex". With this we have a > better name that doesn't clash with audio's usage of stereo. > > Bug: webrtc:7671 > Change-Id: Iebc3fc20839025f1bc8bcf0e16141bf9744ef652 > Reviewed-on: https://webrtc-review.googlesource.com/43242 > Commit-Queue: Emircan Uysaler <emircan@webrtc.org> > Reviewed-by: Niklas Enbom <niklas.enbom@webrtc.org> > Cr-Commit-Position: refs/heads/master@{#21769} TBR=sprang@webrtc.org,niklas.enbom@webrtc.org,qiangchen@chromium.org,emircan@webrtc.org Change-Id: Icf019cb09e07de45821d31d7d8ea7707d01346ee No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: webrtc:7671 Reviewed-on: https://webrtc-review.googlesource.com/44360 Commit-Queue: Ivo Creusen <ivoc@webrtc.org> Reviewed-by: Ivo Creusen <ivoc@webrtc.org> Cr-Commit-Position: refs/heads/master@{#21774}
