Marvin - This feature was cut from 2.1 per comment 2. We're also really late in the game at this point, so adding any additional scope is going to put our FL quality goal in jeopardy. Why is this being added back into scope again?

[Marvin Khoo [:Marvin_Khoo]]

Hi Jason,
The 2.1 scope in comment 3 is original committed to be implemented before partner, so we stick to original planned scope, this thing is on track.

drop me mail if you have further concern, Ajones, Chris, Eric, Blake should agreed with this, or i can give you more history input on this via Skype.

Hi marvin,  yes there is testing concerns and resources for this late in the week of FL.   We'll take this offline to discuss.

As we talked with Marvin this afternoon, he asked if WebM would be supported on Firefox OS 2.1. We revisit this bug, and I found that comment 0 which said "for supporting MSE on Firefox OS (B2G), Enable MPEG-DASH" is not totally right. WebM is not a container option of running MPEG-DASH. In addition, Blake and Anthony Jones had a discussion on irc. Anthony had also confirmed that we need to disable WebM for MSE on B2G to let MP4 for MSE work properly. In short, I would like to say that only MP4 for MSE would be supported for Firefox OS 2.1.

Comment 8

[Marvin Khoo [:Marvin_Khoo]]

Agreed.

Revision for scope: removed WebM support for 2.1 as WebM was not part / included in DASH. 

MSE scope for 2.1,

- Enabling PlatformDecoder to support, MP4 (H.264 + *.aac).
- For MSE APIs scope that Mozilla currently available is listed below,
- http://mxr.mozilla.org/mozilla-central/source/dom/webidl/MediaSource.webidl
- The reference acceptance criteria for above work will be on YouTube.
- We do NOT plan to support MPEG2-TS in 2.1.
- We do NOT support MP3 in MP4.

[QA Update]

* in-moztpe -
* Base on MSE criteria, we just work will be on YouTube website. Therefore, I will focus testing on relevant YouTube video include embed video to others websites.

Update comment.

Revision for scope: removed WebM support for 2.1 as WebM *is* not part / included in DASH.

Marvin, maybe you could be the best one to own this bug. If it's not, please re-assign it. Thanks.

Wouldn't we need test cases then with specific YT videos then? I'm concerned that not having targeted test cases here means that we won't know when we are/aren't regression testing this feature in test runs.

[Edward Chen[:edchen]]

Got it.

I can provide sample video URL in Moztrap.
