Does FreeSWITCH supports Googles VP8 (WebM) Codec
Hello folks from FreeSWITCH, i am using FreeSWITCH with the conference system BigBlueButton, made by people from canada. It works pretty fine, so far. Due to the need that we would like to support more than 500 users in a single video/audio session, we are in interest to use the best codecs. So i listen to VP8 from Google. Does FreeSWITCH support it anyway? I couldn't find something in the FAQ's. I listen something about ffmeg, is it in this abstraction module? Thanks for a short reply and thanks for the good work! Kind regards, Markus
All video codecs is passthrough currently in FS, so it doesn't matter of performance in FS even it might matter in other parts of BBB. I guess you could easily write a passthrough module for VP8 just like mod_h26x. -- Seven Du About: http://about.me/dujinfang Blog: http://www.dujinfang.com Proj: http://www.freeswitch.org.cn Sent with Sparrow (http://www.sparrowmailapp.com) On Thursday, August 4, 2011 at 6:14 PM, Markus Siebeneicher wrote:

From what I could see, a mod_vp8 would be cool because its license is BSD-like and not like h264 and others that have patent restricting use.
The problem is that, afaik there is no endpoints using vp8 nowadays so it would be restricted to some internet application or custom application making use of vp8... Maybe the experts could shed some light on the matter, I don't even know if VP8 would be suitable for phone calls...

I read the Skype is about to start using VP8. This seems pretty odd, considering who their new owners are, but maybe the decision was made long ago. If that's right, the availability of endpoints will change very rapidly.... as long as you can interwork with them. It seems VP8 was designed to be video conference friendly, but I have no idea just how friendly. Google seem to have done serious work on speeding up encode on a PC. Steve
FS supports video, but it's limited support. All video codecs are passthrough only, with no transcoding. I'm not sure whether any module currently provides a passthrough VP8 implementation. If there isn't though then proxy_media ( http://wiki.freeswitch.org/wiki/Proxy_Media) will still let you support that codec. It requires both endpoints support VP8 and at least one audio codec though, and you'll lose some FS functionality (no accessing the audio to do things like record, eavesdrop, inband DTMF detection). -Steve On 4 August 2011 11:14, Markus Siebeneicher <7eicher@gmx.de> wrote:
