How to transrate H264 format stream without a need to transcode

Hi,

I have one incoming H264 format stream and want to transrate it to different bit rates for adaptive bit rate switching. Should I be using the Wowza transcoder add-on for it even though I dont need to actually transcode the format.

Yes, that is the transrate case. See the tutorial here for more information:

Are you running Wowza in stand-alone (/bin/startup.bat) mode? What is log messages do you see when the stream is published?

Charlie,

My source is encoded in h264 and has 9 MBits/sec and I want to transrate to 1MBits/sec. I put passthru in codec at transrate.xml and stream out dont work.

I’m curious - is transrating a stream as computationally intensive as transcoding?
