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-owner@vger.kernel.org [mailto:linux-media-owner@vger.kernel.org] On Behalf Of llarevo@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)? Thanks a lot in advance. -- Felix -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
