1060864 - Adjust b2g bandwidth limits for WebRTC

Status: RESOLVED FIXED

(Core :: WebRTC: Audio/Video, defect)

Description

[Randell Jesup [:jesup] (needinfo me)]

[Blocking Requested - why for this release]:

Since the default capture size in b2g is 320x240 (QVGA), compared to desktop default of VGA, the default bandwidth settings for B2G should be modified as well, doubly so now that H.264 uses the qm_select code to reduce encode resolution as needed (down to 1/2 x 1/2 capture), and to reduce framerate.

As these are prefs, they're easily adjustable by device vendors and QC as well in any case.

Spoke offline with mreavy and these bandwidth limits will help us a lot during start-up on firefox os and these are low risk.

Note that due to recent policy changes, all B2G uplifts needs approval now regardless of blocking status. Please request b2g32 approval on this patch when you get a chance. Sorry for the inconvenience.
