RLouis A. Mamakos: |I'm curious to try dtv the "old" way, with the video in a window done |the hard way. I'd like to be able to watch the video, and hack away |on some code at the same time in another window. The current version |using the DGA XFree86 extension sort of grabs the display away from |the X server for the duration. I'm trying to figure out if it's |"safe" to create a window that's "always on top" and "sticky" (that |is, it moves with the view as you pan around on a desktop) and have |the video blasted into it, within the window frame. I fear that I'm |gonna have to learn much more about how X works than I ever wanted |to.. Yeah, me too. In fact the past two evenings I hacked up dtv to do just that. The keyboard grab is gone, and the live video window tracks when dragging the X window around with the mouse. However, since clipping isn't yet supported by the bktr driver (at least I don't think it is), I've got dtv just pausing capture when the X window is moved partially off the display. Also due to no clipping, I don't let it get pushed behind anything -- it pops itself. So dragging is in, and I plan to add resize support tomorrow night. If you're interested in a copy, I can clean up my source a bit tomorrow evening and make it available. Adding clipping support to the bktr driver would be a nice feature addition. If someone doesn't get get there first, I hope to look into adding it at some point. |I contacted the Brooktree people today, and I'm hoping that I'll get |some docs on the Bt848, as well as their hardware eval board which |looks to have the same sort of tuner assembly on it. They have some |sample software for their hardware eval kit, and I'm hoping source |code which might include how to talk to the tuner over the I^2C bus. If the sample software you get works with the TV/dbx tuner, I'd be interested as well! I've swapped e-mail with Wincast a few times about Wincast tuner specs but so far haven't gotten past the PR tech support folks that don't seem to even know the Brooktree specs are freely available. The official word I get is "SDK beta in 2nd quarter", which is probably some Windoze API, not port mappings. I probably will just eat the long distance cost and call them. Randall
