As long as you found a card number that works, it shouldn't matter. BTW, do you have its card info, like manufacturer, Model number, picture, ..., etc.? What's your app? If you only use it for video surveillance and don't need stereo audio, you may use a low cost capture card, like Sensoray Model 812 (http://www.sensoray.com/products/812.htm) for your application.

RE: HD Capture Card (HDMI and Component) output raw pixels
Right -- not practical, since you need 1920*1080*3*50 = 311.04MB/s bandwidth to transfer from PCIe and save the raw date onto a SSD, at which the PCIe 1.x link x1 (max 250MB/s) can not really meet such requirement. Well, PCIe 2.x link x1 can meet since its max is 500MB/s. Or, using YUYV, a more common format, would be fine, since it requires 207.36MB/s and reduces the storage requirement from 1.119744GB (1920*1080*3*50*60*60, with RGB format) to 0.746496GB (1920*1080*2*50*60*60, with YUYV format).

Your driver load may not be quite right or got some conflicts. According to: http://www.kernel.org/doc/Documentation/video4linux/CARDLIST.saa7134, the Terratec Cinergy 400 TV should be card=8. Have you tried: restart, modprobe -r saa7134, modprobe saa7134 card=8, dmesg | grep saa7134, and checked if the Terratec Cinergy 400 TV showed up correctly? If right, it should be Ok: ffmpeg -f video4linux2 -i /dev/video0 out.mpg ffmpeg -t 30 -f video4linux2 -s vga -r 30 -b 2000k -i /dev/video0 out-vga-2M-30sec.mpg ffmpeg -t 60 -f video4linux2 -s vga -r 30 -b 2000k -i /dev/video0 out-vga-2M-60sec.avi ..., etc. -Original Message- From: linux-media-ow...@vger.kernel.org [mailto:linux-media-ow...@vger.kernel.org] On Behalf Of llar...@gmx.net Sent: Saturday, July 14, 2012 4:29 AM To: linux-media@vger.kernel.org Subject: libv4l2: error dequeuing buf: Resource temporarily unavailable Hi, I'm not sure, if this is the right list, if I'm wrong here, a hint for a appropriate place for my questions would be very appreciated. I have a problem with an analog Terratec Cinergy 400 TV. When I try to capture with ffmpeg, ffmpeg -f video4linux2 -i /dev/video0 out.mpg I get the error libv4l2: error dequeuing buf: Resource temporarily unavailable I'm using Fedora F17. The behavior seems to be pretty strange to me, because xawtv, mencoder, mplayer and tvtime don't have a problem with the hardware at all, ffmpeg has got this problem only with the hardware mentioned above, with a Terratec Cinergy XS, ffmpeg captures without problems. Why reports libv4l2 Resource temporarily unavailable? What are common reasons for that message? What can be a reason that creates the message only on specific hardware (Terratec Cinergy 400 TV)?

Have you tried TVTime and/or XawTV? Also, you may try streamer -c /dev/video0 -n pal -s 640x480 -r 2 -t 10 -o image_00.jpeg to confirm it's really a field order issue. The VLC is tricky.

The chip receives HDMI data from a host like a set-up box or DVD player. It provides a video data interface and SPDIF/I2S audio data interface. We plan to support the HDMI video using the V4L2 framework and the HDMI audio using ALSA framework. Now, what seems to be intriguing us is how the audio-video synchronization will be maintained? Will a separate bridging entity required to ensure the same or whether this can be left upon a user space application like mplayer or gstreamer. Also is there a existing interface between the V4L2 and ALSA frameworks and the same can be used in our design?
