Status: RESOLVED FIXED

(Firefox OS Graveyard :: Gaia::Video, defect)

Build ID : 20130419115238

When I play 640x360 video clip, the bottom of video frame is stretched, sometimes.
(Other resolution looks like find but i'm sure because I have not checked various kind of resolution)
If you can touch the screen to show or remove progress bar, you can see it more frequently.

And more over, left side of frame is blinking.
It seems like the frame is shifted to right by 1~2 pixel.

This problem happens in the case of both local and streaming and both horizontal view and vertical view.

No minate to tef. I confirmed this bug on v1.0.1 buri device. It seems that stretch happens when the video is rendered by HwComposer. No stretch when the video is rendered by OpenGL.

MozBuild sitll can not enable HwComposer on buri. To use HwComposer on MozBuild, I needed to apply following patch. But still have a problem of web content rencering.

Confirmed! Patch coming up

Actually it makes more sense to roll up this fix into the patch in bug 832383. I'll follow up there.

If this is going to be tackled in bug 832383 should we nominate that one instead?

Comment 9

[Lukas Blakk [:lsblakk] use ?needinfo]

Yes, we should block on the fix in bug 832383 - leaving this one open though it could possibly be duped?

Comment 10

[Diego Wilson [:diego]]

I'd rather keep it open to make sure it's verified once the fix for bug 832383 lands

Comment 11

[Diego Wilson [:diego]]

The patch below in bug 832383 should address this
