I'm trying to figure out how to get an STB working with MythTV. The TV portion seems to work only through XVideo - XawTV and Zapping can view TV but changing channels and setting audio has to be done externally.
MythTV seems to want to work with V4L devices. My understanding is that XFree86's v4l module will provide an Xv interface to V4l devices. Is that correct? This assumes the TV is accessible through a V4l driver, ie Xv sits atop V4L - is this also correct? If I'm right about this, the only way to support my hardware would be either: 1. write a V4l driver for the TV hardware and make the X server not manage that hardware or 2. Add direct Xv support to MythTV The latter seems easier to me since Xv is a pretty straight forward API and I already know the X server is managing the TV hardware display (if not specifically managing channels or audio - and that can be done at the application level using vendor supplied tools anyway). The former I'm not sure how to do because I'm not sure what bit of hardware it is I'm trying to write the driver for - is it just the SAA7114 tuner? Or does this *have* to go through the video controller stuff too? I could use a pointer on how to get started here. I've done plenty of app level development (X/Motif/GTK+ based) but its been years since I've done much hardware level stuff. FYI, here is the hardware (all integrated on the motherboard) on the system I'm working on: VIA C3(aka Samuel 2), 733/800MHz - CPU Trident CyberBlade/i1 - Video controller SAA7114 - Video decoder (Tuner) RealMagic 8470 - MPEG 2/4 decoder (Sigma Designs) VIA Tech VT8601 - PCI Bridge (AGP, NorthBridge) VIA VT82C686 - ACPI (SouthBridge) VIA VT82C686 AC97 - Audio controller Realtek RTL-8139/8139C (1 & 2) - Ethernet controllers BTW, I have an updated trident.o (and source) from VIA that supports the Cyberblade on this hardware. I'm not sure if its the same one currently in the XFree86 tree or not, however. -- Michael J.
