A user that attempts to watch a YouTube video on their Inari device will have the video stop with a green screen almost every time.

Repro Steps:
1) Updated to Inari Build ID: 20130415070202
2) Launch the Browser and navigate to
3) Select a video to play (the longer the better) and begin playing.
4) Observe the video as it plays.

At some point in the video playback, the video will prematurely stop and show a green screen.

The entire video will play without glitches or freezes.

I was able to repro it in Inari commercial RIL 1.0.1

The key appears to be having the UI up while the video is playing.  The video appears to be fine if the UI remains hidden.

I do see a slight stutter; I do not see a constant interruption.  I think there's some sort of wifi/network issue at your location

This might get better with the gralloc changes in bug 862397
Confirmed that it happens also in Firefox OS v1.0.1 on unagi. Nominate to tef+.

865091 is fixed. Is this bug still a problem?
Naoki - we'd like to get this off the list if it isn't reproducing.

Still repros on Inari 1.0.1 commercial RIL, but only about 20% of the time.  It also repros regardless of whether or not the UI is visible.

Sotaro told me there are a number of issues affecting video playback here.

Is dupe of bug 863441. By applying temporary fix as in Bug 863441 comment #67, the problem was fixed. A lot of issues are caused by intermittent slow data input.  The temporary fix mitigate the problem by buffering more decoded video frames.
