Hey Folks!

Recently, I ventured out on building a FreeBSD based HTPC and so far I am have been impressed. The only thing that is missing from my configuration is TV capture. I have the recommended hardware, but I have not had any luck with debugging the issue.

I have a Pinnacle PCTV 801e SE YUANRD card which is detected accordingly by my FreeBSD 9.0 system which  I am trying to configure with MythTV. 

Today, I downloaded the two firmware pieces mentioned in the WebCamCompat wiki page and put them /boot/modules. The webcamd module is compiled with the MAKE_DEBUG option to spew debugging information. 

Here is the usbconfig info - 

ugen4.3: <PCTV 801e YUANRD> at usbus4, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON

  bLength = 0x0012 
  bDescriptorType = 0x0001 
  bcdUSB = 0x0200 
  bDeviceClass = 0x0000 
  bDeviceSubClass = 0x0000 
  bDeviceProtocol = 0x0000 
  bMaxPacketSize0 = 0x0040 
  idVendor = 0x2304 
  idProduct = 0x023a 
  bcdDevice = 0x0100 
  iManufacturer = 0x0001  <YUANRD>
  iProduct = 0x0002  <PCTV 801e>
  iSerialNumber = 0x0003  <0F00AED0E6>
  bNumConfigurations = 0x0001 

When I start webcamd I get the following -
