Hi Folks,
I have recently started an enforced refresh of my media server which
included switching out some older PCI cards for PCI-e as the new Mobo
has no PCI slots.
One of the input channels is an analogue composite input from an
external device. I previously handled this with an ivtv based card but
am now trying to use a Hauppauge ImpactVCB-e for this.
The v4l2-ctl tool under the user "mythtv" produces the following:
$ v4l2-ctl -D
Driver Info:
Driver name : cx23885
Card type : Hauppauge ImpactVCB-e
Bus info : PCIe:0000:06:00.0
Driver version : 5.7.16
Capabilities : 0x85220011
Video Capture
VBI Capture
Audio
Read/Write
Streaming
Extended Pix Format
Device Capabilities
Device Caps : 0x05220001
Video Capture
Audio
Read/Write
Streaming
Extended Pix Format
The mythtv-setup tool, using the card type V4L2 finds the card,
correctly identifies it, correctly lists the card inputs (Composite1 and
Svideo) and allows the input to be set to Composite1.
The setup works well enough for tvtime to replay the composite data, but
when I try and connect to it using MythTV I just get a blank screen and
the atached lines in the console log (see end).
Has anyone had any success with this card ?
Cheers
