I found this bug while i'm testing Bug 880587 

1.Open http://imps.tcl-ta.com/cailiang/media/content_e5.html
2.click "HTML5 Video Test" to test html5 video

There are four video files in a single page.
As I enter the page.
Fourth video files are start to play automatically using H/W codec.
First video files are played well by using S/W codec.

But...2nd, 3rd video files cannot be played because it cannot use H/W codec.
H/W codec is held by fourth video element.

Sorry for late response. I am going to work for the bug from now. This change require some new features and need to change some sequences.
Flags: needinfo?(sotaro.ikeda.g)
Depends on: 891445
This qualifies as a new feature, and needs to be followed up in email if we're going to block on this much change this late in the release.

not sure is related, have we tried on Firefox browser? guess this is not only b2g/Firefox OS issue.
This issues is only related to Firefox OS. Firefox OS uses hw codec for video decoding. By it, only one video element can get video codec at a time. If each video elements exist in different app/web content, the hw video codec resource is shared automatically. But if each video elements exist in same app/web content, there is no automatic mechanism to arbitrate hw video codec resource usage arbitration.
This has been around multiple releases, so we're not going to block on this.
