Hi all,<br>
<br>
Been a while since I looked for HDMI capture but perhaps thereare
some new options:<br>
<br>
<br>
HDMI PC ExpressCards for capture:

- claims kernel 2.6.14 or newer is supporting it. Its from US$109.99
to US$150 on Amazon, and launched around Aug 20 2012.<br></div></blockquote></div></div></blockquote><div><br></div><div>I haven't seen this particular device before, but my guess is that it uses a similar chipset to the PCI-X cards on the market which have no support under Linux.</div>
<div><br></div><div>The StarTech website doesn't list Linux as supported. <a href="http://www.startech.com/AV/Converters/Video/HDMI-to-ExpressCard-HD-Video-Capture-Card-Adapter-1080p~ECHDCAP">http://www.startech.com/AV/Converters/Video/HDMI-to-ExpressCard-HD-Video-Capture-Card-Adapter-1080p~ECHDCAP</a> and that documentation is dated later then the mediapool one.</div>
<div><br></div><div>The MST3367CMK chipset information is for the HDMI receiver and gives us no information about what chipset the computer is actually talking too making it hard to confirm any driver compatibility.</div>
<div><br></div><div>The following email thread seems to indicate for a similar device it might use the saa7160 chipset which has a bunch of unfinished drivers but nothing stable and usable in the kernel.</div><div><a href="http://comments.gmane.org/gmane.linux.drivers.video-input-infrastructure/69075">http://comments.gmane.org/gmane.linux.drivers.video-input-infrastructure/69075</a> <br>
