Yes, YUV capture is exactly the same for the 150 as the 350, and only
broke for a very short period of time when rewriting all the DMA code,
and all the methods we use to run interrupts and work queue threads.
It is also interesting the Windows drivers take out YUV capture support
for pvr150/500 cards yet support it for pvr250/350 cards (I *think* it
does for the 250). This is absurd since absolutely NOTHING is different
in the firmware or hardware or interface to get YUV capture from the
card, so that's something I'm really curious about, why did they pull
YUV support for the newer cards in Windows????
Of course that's all capture, now sending YUV to the card and bypassing
the mpeg2 decoding unit (essentially doing the decoders function and
plugging into the hardware inbetween the two units, mpeg2->YUV decoder
and YUV display), is that even done in Windows???, I don't think it is,
and not done in Linux either, there's no success that I know of
anywhere else for sending YUV to these cards display directly (although
one of those 'features' supposidly possible, although it's one of those
phantom features we see so often for products now days, something
iCompression->Conexant kinda wanted to eventually do and as we are
seeing is *possible* but not engineered into firmware or done before).
Thanks,
Chris

It does work for a PVR 350 but the question (if i
remember correctly) was about a 150 and i have no idea
whether that works or not.
mplayer has a decoder that understands the format
coming out of the 350 and can play it directly (with
the correct command line options).

I asked this question a while back, and I got no
response.
With mplayer it does not work (yet).
On the other (dark) side of the world, the windows
drives do not support to
read raw data, so it would be amazing if these
hacker guys manage it.

Awhile back (ivtv-0.1.9 IIRC) it could be made to
work. The
biggest problem is that the data format isn't quite
normal. It's
structured slightly strangely and it took a patched
player to play it.
Nothing inherently bad, just a slight massaging of
the data required.
I remember hearing of it breaking as the driver
evolved, and I
have no idea what the current status is. Doesn't
appear to be any reason
why it *couldn't* work.
