There is an HD capture device from Haugpauge called the HD-PVR. I have read that it can be captured from using cat /dev/videoX > foo.ts. I am curious if there is any way to be able to use Kdenlive to be able to capture from this external USB device? The device is here: http://www.hauppauge.com/site/products/data_hdpvr.html

Mythtv can currently use it as an input to capture HD tv over component cables. That info is here: http://www.mythtv.org/wiki/Hauppauge_HD-PVR

Apparently driver support has been added to kernel 2.6.29.1 and above. Is this an easy thing to incorporate?

Next question if it's not, will I need to convert the video captured via the cat command to from whatever is in the .ts file to DNxHD first to be able to edit it easily in kdenlive?

Any responses are welcome.

Kdenlive can not capture from this device.

thanks for the replies guys. that's too bad for me.

In terminal session enter commands:

# Set the HD PVR's video settings

# Audio IN 0=RCABack 1=RCAFront 2=SPDIF

# Video Input IN 0=component, 1=s-vid1(front) 2=composite1(front)

# if using SPDIF the ctrl "audio_encoding" has to be 4 [3=AAC - 4=AC3] or you get an empty file

# audio_encoding [3=AAC - 4=AC3]

# I found to use the SPDIF the STB has to also send AC3 or you get silence

sudo /usr/bin/v4l2-ctl --verbose -d /dev/video1 -c audio_encoding=4

sudo /usr/bin/v4l2-ctl --verbose -d /dev/video1 --set-audio-input=1

sudo /usr/bin/v4l2-ctl --verbose -d /dev/video1 --set-input=1

sudo /usr/bin/v4l2-ctl --verbose -d /dev/video1 -c video_bitrate_mode=1

sudo /usr/bin/v4l2-ctl --verbose -d /dev/video1 -c video_bitrate=13500000

sudo /usr/bin/v4l2-ctl --verbose -d /dev/video1 -c video_peak_bitrate=20200000

sudo /usr/bin/v4l2-ctl --verbose -d /dev/video1 --set-ctrl brightness=125 --set-ctrl contrast=60 --set-ctrl hue=15 --set-ctrl saturation=85 --set-ctrl sharpness=130





# Capture footage to the capture drive

ffmpeg -i /dev/video1 -vcodec copy -acodec ac3 -ab 448k ~/capture.mp4


Then import the clip into Kdenlive. It is my preferred method. I get great capture, and I can edit in the BEST editor out there. The only drawback is you can't monitor when using the line command. If you absolutely MUST monitor while capturing, perhaps try Smplayer? Or VLC? There is also the "T' feature in the command line that plays stdin, but I have not used it with my ffmpeg command so I can't say how it may be accomplished.
