The youtube video slider does not function properly. After dragging the slider to skip ahead in the video, the slider will automatically jump to the end of the video. After this occurs, the slider will repeatedly snap to the end of the video, and the user will have to drag the slider multiple times in order to resume playing. Repro Steps: 1) Update a Buri to BuildID: 20140409130909 2) Launch Browser app. 3) Watch a youtube video. 4) Drag the youtube slider forward until it is past the buffered area. Actual The slider jumps ahead to the end of the video, and sticks there. Expected: The slider jumps to the point indicated by the user, and resumes playing from there.

Does this happen on 1.4?

I am unable to reproduce the issue on 1.4 v1.4 Environmental Variables: Device: Buri v1.4 MOZ BuildID: 20140409000202 Gaia: 26983f356ecb1bcf30e862d334b5de790071803e Gecko: e450e07e3a58 Version: 30.0a2 Firmware Version: v1.2-device.cfg

I'm wondering if this is a fast seek regression.

(In reply to Jason Smith [:jsmith] from comment #3) > I'm wondering if this is a fast seek regression. Chris - What do you think?

Possible. Can we get a regression range search?

(In reply to Chris Pearce (:cpearce) from comment #5) > Possible. Can we get a regression range search? Yup - I'll get someone assigned to do that.

This is either caused by bug 631058 or bug 778077.

(In reply to Jason Smith [:jsmith] from comment #8) > This is either caused by bug 631058 or bug 778077. Chris - Do you know which bug caused this regression?

I don't know. I can't reproduce this bug in my Otoro. But I can reproduce a bug where if I seek to the end of a m.youtube.com video (into an unbuffered range) and then try to re-play the video the browser locks up. Sometimes I get audio playback, but I don't see the video frame update, and the UI is unresponsive. And I see lots of this in adb logcat: E/libgenlock( 104): perform_lock_unlock_operation: GENLOCK_IOC_LOCK failed (lockType0x2, err=Connection timed out fd=246) E/Adreno200-EGLSUB( 104): LockImage() genlock_lock_buffer GENLOCK_READ_LOCK failed

That may eliminate the device dependency here.

No. We don't have one of those in the Auckland office.

Eric - Can someone on your team take this since you guys have access to production devices?

Sure. Assign to myself first and I'll delegate to Bruce or Blake after discussing with them.

Bruce will work on this.

I've tried the latest master, I haven't seen this issue happens yet: - Gaia 265e1ac4ee71ad6190335c974bfce33f783edfce - Gecko https://hg.mozilla.org/mozilla-central/rev/ea25086073c8 - BuildID 20140427160202 - Version 31.0a1 - Firmware Version: v1.2-device.cfg I can reproduce this issue on master build with BuildID:20140409130909. But I only encountered maybe 3~5 times this afternoon. The reproduce rate is not so high on my environment. Hi rkuhlman, Do you have any specific youtube sources by which we can more easily reproduce this issue? Would you mind helping me try the latest master to see if we can still reproduce this issue on that? Thanks for your help in advance.

I had the most success when watching videos that are 5+ minutes in length, no specific sources. I am so far unable to reproduce the issue on todays master build.
