Hello All ~ I am trying to get freevo working with an easycap usb hardware capture/encoder device. I know this device has seen some bad press, but I've had good success ripping old VHS tapes using it (Ubuntu 10.10, mplayer/mencoder). for example I can play video in mplayer using this:
$ /usr/bin/mplayer -tv driver=v4l2:norm=NTSC_M:width=640:height=480:outfmt=uyvy:device=/dev/easycap0:input=5:fps=30:buffersize=16:alsa:amode=1:forcechan=2:audiorate=48000:adevice=plughw.2,0:forceaudio:immediatemode=0 -hardframedrop -ao alsa -msglevel all=9 tv:// Notable in this for me are: driver=v4l2 device=/dev/easycap0:input=5 /dev/easycap0 is an ln to /dev/video0 and input=5 is S-Video in. I've been trying to configure freevo with the same machine/capture device to display video from "Watch TV" (I have freevo set up and otherwise working fine afaict). I am not worrying about sound... yet. I see from ps that freevo invokes this maplayer command: /usr/bin/mplayer -slave -vo xv,sdl,x11, -ao oss:/dev/dsp -autosync 100 -nolirc -nojoystick -autoq 100 -screenw 800 -screenh 600 -fs -nocache -tv driver=v4l2:freq=0.000:device=/dev/video0:input=0:norm=NTSC:width=640:height=480:outfmt=yuy2 tv:// Notable are: driver=v4l2 (same) device=/dev/video0:input=0 (different) /dev/video0 is fine (see above), but input=0 is a problem - it is a separate composite input on the usb device and so I get no video received. An obvious question is: "Do I get video when I hook up an input to the composite input?" Ans: I don't know yet, but will be trying that, and will post results. But I believe there is a deeper problem. As part of debugging this I have run: $ freevo vg -- -c /etc/freevo/local_conf.py -vv with the following results: video0 () ----------------------------------------- ----------------------------------------- Driver: easycap Card: EasyCAP DC60 Version: 00000900 (09.00) Capabilities: 0x05020001 Enumerating supported Standards. 0: 0x21d PAL_BGHIN 1: 0x0 NTSC_N_443 2: 0x400 PAL_Nc 3: 0x0 NTSC_N 4: 0xff0000 SECAM 5: 0x1000 NTSC_M 6: 0x2000 NTSC_M_JP 7: 0x800 PAL_60 8: 0x4000 NTSC_443 9: 0x100 PAL_M 10: 0x10000021d PAL_BGHIN_SLOW 11: 0x1100000000 NTSC_N_443_SLOW 12: 0x100000400 PAL_Nc_SLOW 13: 0x2100000000 NTSC_N_SLOW 14: 0x100ff0000 SECAM_SLOW 15: 0x100001000 NTSC_M_SLOW 16: 0x100002000 NTSC_M_JP_SLOW 17: 0x100000800 PAL_60_SLOW 18: 0x100004000 NTSC_443_SLOW 19: 0x100000100 PAL_M_SLOW Current Standard is: 0x21d Enumerating supported Inputs. 0: CVBS0 1: CVBS1 2: CVBS2 3: CVBS3 4: CVBS4 5: S-VIDEO Input: 0 Width: 640, Height: 480 'easycap' is an unknown driver TV_VIDEO_GROUPS = [ ] I don't completely understand this output, but I think freevo is successfully(?) probing the hardware (reported info looks correct). But I can see at least two problems: Input: 0 <~ comnposite CVBS0, wrong! I want Input: 5 (see above), and: 'easycap' is an unknown driver So (finally!) two questions I hope the experts can help me with: 1. How do I change Input: 0 to Input: 5? I have fiddled around with TV_VIDEO_GROUPS and have been unable to get anything other than 0 there. and, 2. What to do about the unknown driver? A couple of further bits of information/questions re: this.. I have not told freevo to try to use the easycap driver in the config anywhere, and a sub-question, since I have hardware which is known working using v4l2 driver (which uses the easycap driver "underneath"), why does freevo appear to be going around v4l2 to access the hardware driver directly? I had understood that v4l2 compatible hardware was ok... I plan to keep digging as time permits, but any advice/pointers would be great!
