Few days ago I finally managed to get DVB-C tuner with on-board MPEG-2 decoding. Installed PCI board on PowerMacintosh 7500 (PowerPC 604e) and it has worked smoothly from the beginning. Except for one small detail: OSD colours (of VDR) were wrong. But wait... I saw exactly the same thing with DXR3 (<URL:http://www.linuxtv.org/mailinglists/vdr/2004/07-2004/msg00475.html>). I assume that byte order conversion had got implemented in kernel DXR3 driver and code in VDR DXR3 plugin needed removing. At this point I looked at source code of "dvb_ttpci" kernel driver. Colour space conversion happens at "linux-2.6.11.7/drivers/media/dvb/ttpci/av7110_hw.c", beginning from line 952, function OSDSetPalette(): --- blend = (color & 0xF0000000) >> 4; yuv = blend ? RGB2YUV(color & 0xFF, (color >> 8) & 0xFF, (color >> 16) & 0xFF) | blend : 0; --- Now, inserting this byte order conversion before colour space conversion fixed OSD colours for me: --- color = ((color & 0xFF) << 24) | ((color & 0xFF00) << 8) | ((color & 0xFF0000) >> 8) | ((color & 0xFF000000) >> 24); --- It supposedly breaks OSD for hardware of opposite byte order, so some kind of byte order detection logic around it. I do not know how that is supposed to be done in kernel code. -- "pienena / Paavo "Rainbow Rat" Hartikainen minusta / E-mail: pahartik@xxxxxx tulee / URL: http://www.sci.fi/~pahartik/ rotta" / EFnet: pahartik at #Atari and #LionKing
