frame_height, height, y_height etc...
I'd previously been working on the assumption that the frame_height was the height of the inner picture region... and height was the height of the outer frame. Then upon readnig the spec... where it calls the outer part the frame and the inner part the picture region... i assumed i'd made a mistake and that frame_width is actually >= width in the theorainfo structure... ie

encoder settings
Hi! Some background: I am trying to create an application that would encode video taken by USB camera using Theora and then send it to the client. I have almost succeeded, but I have one problem. When I grab video frames from the camera and encode them they form 4KB OGG pages, then I send them over TCP/IP to the client application. Since I want to achieve as small latency as possible I

encoding image from a webcam
I'm trying to encode a picture from my webcam using the theora codec. The final "product" must encode a frame, send it over the network and decode it on "the other side". For now, it must only work locally so we don't care about the transmission. This is what I've understood till now: I have a char * buffer from the camera RG24,I convert it to YCbCr 4:4:4, I

Server based audio merge
Hi Allen, <p>>>True, but there is one critical place where it's necessary to mix at > least two streams--when someone's trying to break into a stream.

You can simply have

Theora 1.1 rate controller
Hello everyone, I'm currently developing an adaptive videoconferencing application based on Ekiga which uses TFRC as a congestion control mechanism to adapt the video encoding rate according to the quality of the network experienced. My goal was to use the open-source Theora codec for video transmission. Unfortunately, it seemed that Theora 1.0 did not properly implement any correct CBR mode.
