Jan Ozer has done a lot work comparing these CODECs.

Hello there:

Have a look at: http://support.on2.com/h264_faq.php ,it's a good article about h264 versus vp6. Basicly what is your project about? What do you want to achieve in terms of video quality? 248k is a bit low for live streaming if we think that HD starts from 1mb.

Regarding 248k being a bit low, that really depends upon the nature of the content being streamed and the available bandwidth. Not every live webcast requires HD resolutions, and 248k is likely to reach a lot more people than 1Mb.

Hello Dave:

Yes indeed you are right but I was saying about HD because he said about H264 which is the encoding standard for HD video broadcast. Here is what we use to do flash streaming: http://www.blinkotv.com/files/pdf/blinko...ive_hd.pdf You see there how to do it and what are the advantages. Of course the download speed of the viewers needs to be at least equal with the bitrate he is using to stream, if they want to view without having buffering issues. It also depends on what he needs to stream, the webcasting software.
I just found this article which is a good start in choosing a codec or another:

See me offline if you need additional information about streaming software or codecs.
