To show that the video is playing. I hear sound. But there are no images displayed.

Hello William - I am not able to reproduce this on Flame using: Gaia 9b6d7357031f2412b18a2fb140d5c974842d4393 SourceStamp fbb3b8be8f6c BuildID 20140725000201 Version 32.0 Base image: V122 I tried with both the Marketplace app and in the browser. Can you please confirm how you flashed the device and what base image you used? Thanks.

Hello Marcia I'm using a Geeksphone Peak to test out 2.0. The image I used is the one provided by Geeksphone every night here: http://downloads.geeksphone.com/

The image I used is the one > provided by Geeksphone every night here: http://downloads.geeksphone.com/ Unfortunately the Peak builds are a bit different than what we are testing, and this isn't an issue on the Flame reference device with the latest build. Removing blocking flag since this is a Peak only issue and doesn't affect the Flame.

In firefox OS versions 1.4 and 2.0 no video image is not displayed. If the sound is heard. Occurs from early July. As happened in versions 2.1 and 1.3 https://videos.cdn.mozilla.net/uploads/mozillaorg. Check mp4 videos not shown. ogv and webm if they show the image. v2.0 updated on 21.08.2014

This may be a duplicate of bug #1056343 (or vice versa), where the same behavior is reported for Linux and OS X. (Hopefully someone will check Windows soon.)

Peak is no longer supported.
