H264/AVC composition time

After reading through the userguide 2.0 and the posts from the forum, I think I can use the sample from http://community.wowza.com/t/-/46 to receive the audio/video stream over RTP and send it over RTMP with Wowza rtp live encoder to the flash client. I will go ahead to test this feature.

two question ons this, (1) in the AV RTP stream, video and audio are in seperate ports. Currently in our A/V RTP stream, video codec is H264 and audio codec are Speex/PCMU. Does the wowza RTP live encoder support those video/audio codecs? Any other other A/V codecs are supported in currently wowza 2.0. [Quick Update, I followed the link above to play a audio stream with speex, I didnot hear any sound. I didnot see any error in parsing SDP file from server log. Any thoughts?]

(2) In the other direction, from the flash client to RTP servers. Is there any live encoder to encode/convert the A/V stream over RTMP into another A/V stream over RTP to a remote RTP server. I didnot find out the info from either the userGuide or the forum. Currently I have to retrieve the raw A/V packets from RTPM stream and maunally send them out over RTP. I wonder if there may exist an easy solution.

Thansk a lot,
