I was playing around with V4l2-ctl, and noticed an error in the units displayed. $ v4l2-ctl -d /dev/video1 --get-tuner Tuner: Name : Television Capabilities : 62.5 kHz stereo lang1 lang2 Frequency range : 0.0 MHz - 268435455.9 MHz Signal strength/AFC : 0%/0 Current audio mode : mono Available subchannels: mono Either the frequency range should be reported in Hz, not MHz, or the decimal place needs to be moved 6 places to the left. For reference, more info on the specific device. $ v4l2-ctl -d /dev/video1 --info Driver Info: Driver name : cx8800 Card type : ATI HDTV Wonder Bus info : PCI:0000:07:01.0 Driver version: 8 Capabilities : 0x05010011 Video Capture VBI Capture Tuner Read/Write Streaming -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
