846571 - Embedded youtube videos don't use Gaia Video app, inline playback is slow and stutters

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: Gaia::Video, defect, P3)

Description

[:Harald Kirschner :digitarald]

After having bug 834965 fixed I tested a few videos. They now play inline whereby I had expected them to open the Video app, like videos do on the youtube website.

The inline playback in my tests was slow and stutters badly. I guess they use the Webm software codec. Playing the same videos in the Video app was "buttery".

This affects all apps and websites that embed youtube videos (there are a lot).

We are getting html5 video (ie webm):

But we don't use the hw decoder for webm afaik, hence the poor performance.

Will the media team take a look at this and see if it is still a problem?

Confirmed mpeg4 video playback. No problem about inline playback.

Setting this back to NEW. UNCONFIRMED refers to the filer status, not the bug status.

Sotaro, can you clarify whether we still don't use the HW decoder for Webm, per comment 1? If we don't, would that still cause the performance issues in question?

Comment 5

[Sotaro Ikeda [:sotaro]]

Current b2g try to use HW decoder for webm playback if the phone's gonk is since JB. It is fixed by Bug 986381.

Does that mean we can go ahead and close this out as obsolete?

Comment 7

[Sotaro Ikeda [:sotaro]]

Yes. We can close this bug.
