We're using some assembler based stuff that a student of mine found on the web somewhere. It appears to be called CCVT and be by some people called Nemosoft. We can convert and render at frame rate so it must be fast. I've searched for it and this looks similar (although contains far more files): http://cvs.luon.net/sweat/common/ And this describes it: http://www.smcc.demon.nl/ccvt/ Derek ---- In reply to ----- Date: Mon, 5 Nov 2001 12:38:07 -0800 (PST) From: <ssingh@xxxxxxxxxxxxxx> To: <video4linux-list@xxxxxxxxxx> Subject: Fame GTK Hey everybody, I am trying to write a gui for the fame mpeg encoder using gtk and I'm having some difficulties. Basically the only way I know how to draw to the screen with GTK is with gdkDrawRGB() but since the encoding engine keeps the frames in the YUV colorspace this requires a conversion which I've implemented but as I expected is very slow. I would like avoid messing with the encoding thread as little as possible so as to keep it fast. Anybody know of a fast conversion routine. Maybe a V4L solution to capture in YUV and RGB to two different buffers... I doubt it. I know this isn't a GTK mailing list but if anybody has ideas on that end, I'd appreciate them.
