Details
1. Launch Firefox (Fennec)
2. Enter "about:config" in URL address field
3. Find "media.android-remote-codec.enabled" and enable it
4. New a tab
5. Go to youtube and play some videos, e.g.,
https://m.youtube.com/watch?v=ki01LoQ_XRA
https://m.youtube.com/watch?v=w2GebXqQMF8
https://m.youtube.com/watch?v=_qCrV5lmpQ0
Actual Result:
- There are a lot of missing frames.
Expected Result:
- No missing frames.
Check the droppedVideoFrames in WebIDE:
- Use "document.querySelectorAll("video")[0].getVideoPlaybackQuality()"
- Result: VideoPlaybackQuality { creationTime: 270046.775, totalVideoFrames: 7167, droppedVideoFrames: 6649, corruptedVideoFrames: 0 }
By the way, this issue cannot be reproduced when "media.android-remote-codec.enabled" is disabled.

I think those choppy or playing video not smoothly issues are related to repeatedly memory copy by current code design. Set the dependency to bug 1295106 which intends to solve performance issue by shared memory.
