Status: RESOLVED INCOMPLETE

(Firefox for Android Graveyard :: General, defect)

Description

[donrhummy]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:40.0) Gecko/20100101 Firefox/40.0
Build ID: 20150826023504

Steps to reproduce:

Played this video directly in Firefox Beta on Android:

https://g-design.storage.googleapis.com/production/v5/assets/g-voice-flow.mp4

(On Nexus 5, Android 5.1.1)


Actual results:

Despite playing and replaying the video 4 times, every time it skipped frames so that they video was always behind the audio and moved slowly.


Expected results:

It should have played correctly with no dropped frames as it does in Chrome on the same Nexus 5.

I'm able to reproduce on N7 (5.1.1), all current channels.

On Galaxy S5 (4.4.4), I don't see this issue. The video/audio is played the same way as it does on Chrome.
