1210175 - simulcast support for H264

Status: NEW

(Core :: WebRTC: Audio/Video, enhancement, P3)

Description

[Byron Campen [:bwc]]

Right now, we only get a single H264 encoder per webrtc.org channel. We either need:

1) The ability to have multiple encoders, each associated with a single simulcast stream in the webrtc.org code.

or

2) Support for encoding multiple resolutions/framerates/bitrates/etc in the H264 encoder, along with the plumbing necessary to associate these encodings with the corresponding simulcast streams in the webrtc.org code.

Simulcast is a P1, but h264 in simulcast could follow the initial release if need be.

Mass change P2->P3 to align with new Mozilla triage process.

Hi guys,
Is there any plan to implement h264 simulcast in FF too?
seems that chrome is almost ready to ship it:

"We have implemented to reject all Firefox from the conference, only Chrome and Safari allowed, and since then we had no problems."

What can I say? Sic transit gloria mundi.
