I didn't seem to have an issue:

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+.

Comment 6

[Natalya Kot [:nkot]]

Bug 865091 blocks the STR of this bug.

Comment 8

[Daniel Coloma:dcoloma]

If this happens after fixing bug 865091 this should be a blocker

Comment 9

[Andrew Overholt [:overholt]]

Once bug 865091 is fixed we'll find an assignee here if still necessary.

Comment 10

[Robert O'Callahan (:roc) (email my personal email if necessary)]

865091 is fixed. Is this bug still a problem?

Comment 11

[Alex Keybl [:akeybl]]

Naoki - we'd like to get this off the list if it isn't reproducing.

Comment 12

[Chris Kreinbring [:CKreinbring]]

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.

Comment 13

[Andrew Overholt [:overholt]]

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

Comment 14

[Sotaro Ikeda [:sotaro]]

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.
