I don't reproduce that anymore ... ?
(In reply to Alexandre LISSY :gerard-majax from comment #9) > I don't reproduce that anymore ... ? I remember the bug was occuring when playing the videos within the app. Today, I'm back fighting with that bug that makes me unable to start videos from within the France 24 app and I have to long press, open in a new window, and there it works.
Right, loading within the app is currently blocked by tracking protection as documented on bug 1174532 comment 32. Once disabled, I can play videos within the app and I have no sound. Opening the same video in Browser, I have sound.
Blocks 2.5 with a P3 priority.

Priority: -- → P3
A regression window cannot be found for this issue. There are builds for about a month between 7-17 and 8-17 where the video will not play at all when clicked on. This issue does not occur before this and does occur after.

Created attachment 8681053 [details] Log : Successful / Fail case comparision From the log, we can see the app doesn't get the "audio focus" from the system app, so it can't be playback. --- Hi, Evan, Could you help me check this issue? Thanks!

Hi Alastor, After investigated, the root cause it that gaia just cannot receive the `activestatechanged` event from gecko when the normal audio channel belonged to "France 24" want to play sounds. Looks like it is a gecko bug.
Component: Gaia::System::Audio Mgmt → AudioChannel
Looks like a 3rd-party app can play audio, but it cannot play video. For example, SoundCloud can play a mp3 music, but France 24 cannot play a video wit sounds. So is there something wrong with handling a video in gecko?
Created attachment 8681184 [details] Log : wrong window ID After register the AudioChannelAgent, we'll send the event to notify the system app. However, this event can't send correctly. It would be stopped in the TabChild because of the wrong window ID. --- Hi, Baku, Could you help me check this situation? It seems the we are in the special DOM window case, we would send the event to the wrong TabChild. Thanks!
I have also notices that pauseing the video I cannot resume playback when in the France 24 app. When I open the same video in browser it's working as expected.
Created attachment 8682405 [details] Log : window ID (scriptable parent v.s. real parent) From the log, it seems that it's also the nested mozBrowser frame case. The owner of the MediaElement is another mozBrowser frame, so we can't send the event out to the system app.

According to comment19, it's the same root cause.
