Hello everyone
A few weeks ago, I bought a Video Encoder Card in Japan with the goal of
using it there in a MythTV box.
The card is branded "BUFFALO" and is called "PC-MV5L/PCI". The package
says: "MPEG2 Hardware Encoder, TV tuner & VHS video capture board" (in
Japanese).
When booting my system, the kernel tells me that the card is unknown and
that I should mail details to this mailing list (details are appended
below). [Loading the firmware seems to be ok, though.]
I compiled the latest kernel 2.6.25.3 from kernel.org to make sure I am
not missing any important recent additions.
The main chips on the PCI board are labeled:
XCEIVE XC2028ACQ
CONEXANT CX25843-24Z
CONEXANT CX23416-22 MPEG II A/V ENCODER
hynix 625A (memory?)
As far as I can see in drivers/media/video/ivtv/ivtv-cards.c there might
be a chance of getting this to run, since both the tuner (XC2028) and
the MPEG2 Encoder (CX23416) seem to be supported by IVTV for other cards.
Unfortunately, I have no clue how to come up with a new entry for
ivtv-cards.c to recognize my device. I can provide more details about
all the logic chips on the board, contents of the Windows driver cd,
photographs of the board, or anything else. Just let me know.
If anyone is able to help, I'd appreciate it very much!
Thanks,
Peter
