Hello people.
I've been toying (fighting) with NextPVR (ver 2.6.2... cool software, BTW) without making any progress, so I guess I can use some help.
I'm setting up a PC as a "proof of concept" before investing in dedicated equipment (to see if I can get all the components to play nice together), and as parts of my test I'm trying to record live tv on a Windows XP machine. I have an ATI TV Wonder Pro installed on the PC, but it's quite obvious the lack of a hardware compressor is a big hurdle, so I'm going for the "plan B"
I'm trying to do the testing with a USB device I have had sitting around for years (Dazzle DVC170), that is supposed to have hardware compression (as a matter of fact, judging by the CPU use while using the Pinnacle software, it does). I've connected a composite source to the DVC170 and I know it's working (checked using a 3rd party app, DVCCap), but I can't seem to make it work with Virtualdub or any other program for that matter.
I ran filtercheck (log attached) and, although I'm not sure what everything means, there's an entry under AM_KSCATEGORY_ENCODER and one under AM_KSCATEGORY_MULTIPLEXER. I added the following entry to analogdevices.xml:
<Device filter="Dazzle DVC170">
<Name>Dazzle DVC170</Name>
<Type>HARD_ENCODE</Type>
<FilterEncoder>Dazzle DVC130/DVC170 VIDEO Encoder</FilterEncoder>
</Device>
and now the DVC170 shows up on the "devices" list. I added one "channel", setting the Composite input as "channel 1" (I've previously set the other inputs as channels as well, but the results are the same). When I select "Leve TV", though, all I get is a blank screen, and I don't know what's going on. I see some stuff get's reported as "missing" on the npvr log, but I don't know if those things are required to get this thing to work.
I've seen mentions about using GraphEdit to try to diagnose what's going on, but, alas, I have no idea how to set up a graph on it. The attached image shows the pins on the DVC170, if it helps. There's also a simple description of the subjacent hardware here: http://www.linuxtv.org/wiki/index.php/Pi...r_(DVC170)
Any help would be appreciated.
