I am having a few problems with motv its operation with savage display cards. The more recent software updates have fixed a number of past problems - we now have all the hardware back in one box - it runs w/o crashing. The basic image capture and display works fine if I use -remote and -noscale on the command line for motv. No problems with three channel capture, overlapping windows, or a window appearing on more than one display. We can deliver to our customer with what we have, but there are a few remaining problems we would like some help on. The configuration: - dual Pentium III system (866mhz, 512M ram) - three WinTV capture cards (BT878, Rev 11) - three (of 4) S3 savage 4 displays (rev 04) on a multihead card - Red Hat 7.2 (2.4.9-13, or updated with 2.4.18-pre7 kernel, XFree86 4.1.0) - xawtv 3.68 (downloaded recently) - Xinerama is enabled Drivers for both bttv and savage are unchanged from the kernels / XFree86 provided. The problems... - I must disable hardware scaling (-noscale) to get any reasonable image to appear. The default gets me a static bright green image in place of the video. This limits the maximum size of the video image. I know with other display cards we can get at least one channel of hardware scaling. Any thing we should change for the savage cards (other than replacing them :-(). - I cannot capture a still - I get a window labelled "Error" with a series of messages similar to... conv: 15 bit TrueColor (BE) => 8 bit static gray ... conv: 24 bit TrueColor (LE:bgr) => 24 bit TrueColor (BE:bgr) - trying to capture a video gets the same errors plus... rate: queueing frame twice (1) [or (2)] Do I need to change display resolution (depth=24, bpp=32) or is something else broke? Should I consider stepping up to the new version of XFree86 or savage drivers? A related set of questions... We like the basic interface of motv, but would like to see... - the control buttons on the video window (don't need the pop up window) - [option to] remove the menu from the pop up window (so the users can't screw up the configuration file) - a button added for the "Scales" (brightness, contrast...) - a button added to auto scan the configured channels (to fill the images in the pop up window) Are these hard to do and where should I look in the code to implement them? I also understand OpenMotif 2.2 implements tool tips (pop up text for widgets) Are the buttons and/or windows subclassed from XmPrimitive or XmGadget so they could use them? I wouldn't mind putting a couple weeks of work on these kind of changes. Thanks. --Mark H Johnson <mailto:Mark_H_Johnson@xxxxxxxxxxxx>
