Any Linux compatible capture devices?

I'm looking to get a composite capture card for my PC running 64-bit arch, but I'm finding it rather difficult to locate any that will for-sure work.

Does anyone know of any that work with Arch (particularly with the more recent kernels)?

Thanks!

I used ``EasyCAP USB 2.0 Video and Audio Capture Card'' to convert the old vhs. It works fine with gstreamer.

Hmm ya, there seems to be a general consensus on the internet from what I can tell that that's the one to get. Pretty cheap on eBay, so I think I'll pick one up there.

Thanks!

I do not know if it is still necessary, but at the time I made this file:

/etc/modprobe.d/tvcard.conf

options em28xx card=35

And here is the command line I use to record. It creates an high quality, high space wastage, easy to cut file.

( gst-launch-0.10 -t -e -v avimux name=mux ! filesink location=a.avi alsasrc device=plughw:1 ! 'audio/x-raw-int,rate=48000' !  queue  ! mux.  v4l2src device=/dev/video1 queue-size=16 ! 'video/x-raw-yuv,width=704,height=576' !  queue ! deinterlace mode=1 ! videorate ! 'video/x-raw-yuv,framerate=(fraction)25/1' ! ffenc_h263 bitrate=5000000 max-key-interval=1 ! mux. ) & sleep 3600s ; kill -2 $!

It records for an hour in a file file called a.avi. You can use avidemux to cut the file as needed and your favourite tool to transcode in your favourite format. gstreamer is the only program that gave me always perfectly synchronized audio.

There are some bullshit on the Internet about the audio quality. It works fine, but you have to use the rate of 48000, as you can see from the commandline.
