Recommended 2 input hardware encoder

Recommended 2 input hardware encoder

[Brandon Jenkins]

Hi all,

I am looking for a Linux compatible board which has 2 analog
svideo/composite inputs (NTSC) on a single bracket. Anyone know of
such a thing? A tuner is not required, but a hardware encoder for
mpeg-2 is.

Thanks,

Brandon

If you want to do two captures simultaneously, you'll need two MPEG
encoders.

The PVR-500 (MCE version linked here) is one such device that has two
encoder chips:

http://www.hauppauge.com/pages/products/data_pvr500mce.html

You may need to wire up a custom cable to one of the internal white
header connectors to use the second MPEG encoder with an input other
then the 2nd tuner.

It's well supported by the ivtv driver for CX23416 based devices.

You can probably get the card cheap off of eBay.

Andy

Simultaneously, I assume you mean.

You could use a Hauppauge PVR-500, which *I think* has video inputs for
both channels, with a header bracket... and I think Limux Media Labs has
some cards that fit that spec, too, but I'm not sure.

The Hauppauge PVR-500 has two hardware MPEG-2 encoders onboard, and
two cable tuner inputs on the mounting bracket. However, as the card
itself only has one set of baseband inputs, you'll need the additional
bracket (see http://registration.hauppauge.com/webstore/accessories2.asp?product=av_cable)
for allow two sets of composite/S-Video connections to be used at the
same time.

Thanks for the replies thus far. I should have clearly stated the
second bracket requirement of the PVR-500 is a stopper for me. I am
looking to build a machine which is capable of 10 analog captures
using 5 PCI boards via svideo and l/r audio. The second bracket on the
PVR-500 makes the card a no go for me. I will look into Linux Media
Labs provided their site comes back online.

Windows cards which support this are NVidia DualTV, Lumanate Angel II.
I don't believe there is support for the ViXS chip yet, and I don't
know if the Lumanate cards are Linux supported. They are not by
Lumanate.

Yup, you should.  You may have interrupt and bus-bandwidth problems at
that level.  It's definitely going to be critical what motherboard and
disk controller you pick.  Is there any reason you can't put it in
multiple chassis?

Jay,

Thanks for the reply. A separate chassis would require administrating
a second system or getting a PCI expansion box. Both doable, but I'd
rather cram it all into one system and test the loading.

FWIW - Supermicro MB and PCI-E add on card for storage.
