CX88 Blackbird together with ivtv?
« on: May 25, 2005, 09:51:11 pm »
hello,

i recently built a htpc with a wintv pvr-350, this works very well with the ivtv driver. About two weeks ago I figured it would be cool to have a second tuner in the box and i found a cheap Winfast TV2000XP Expert. Unfortunately I have not been able to get this to work correctly. The picture is extremely washed out with very little collour and there is no sound. The 350 card still works well. Is it possible to use both types of card at the same time?

I am using fedora core3 with the atrpm distribution of ivtv and the cx88 drivers. Can someone here help me or point me to some "fix it in 10 simple steps" page that i have missed...

cheers

your card seems to not use hardware encoding with blackbird design

compare your card

hmm i fail to see any mention of "blackbird" or chipsets on the pages you mentioned. Isn't the blackbird driver for the Connexant CX2388X chipset?
The card I have here is using that chipset according to the specification in the manual.
Am I using the wrong driver for that chipset?
Which driver should I be using?

thanks for your reply =)

Did you ever find an answer to the problem?  Did you ask the ivtv/myth teams?

'Blackbird' is the 'code-name' given to Conexant's reference designs for MCE compatible video capture devices.

In the context plutohome uses the name 'blackbird' it means any PVR tuner card featuring the Conexant cx23416 MPEG encoder which isn't already supported by the IVTV driver project.

e.g. Leadtek LR6632 or Leadtek PVR2000 card and generally any card which uses the Conexant CX23416 encoder device (apart from PVR250, PVR350).

The card you have, frans, is a regular 'software' encoding card which does not have an onboard MPEG encoder.  Drivers for your card (if available) can be found in the standard V4L code ( newbielink:http://www.linuxtv.org [nonactive]).
