grabber problem

  • Hi,


    When I take a screenshot I get an error like this:


    ssh in: hyperion-v4l2:
    ssh in: version : V1.03.4 (brindosch-c750c41/dc6a602-1522918225
    ssh in: build time: Apr 5 2018 01:57:25
    ssh out: V4L2GRABBER ERROR: Cannot identify '/dev/video0' ERROR 2, No such file or directory
    sftp getFile(./screenshot.png, java.awt.Image)



    Could somebody help me with this issue?


    Many thanks

    Now I have taken an screenshot. The grabber does work. It is an UTV007


    I think it is something with the json file

  • I have the exact same problem I re-soldered some parts, connected power to all four corners as I had voltage drops I could see some color changes on the strip. Before this my video grabber was working fine, now that i re soldered it is working fine except the grabber i keep getting a black Image in the log files I can see the grabber starts fine and I don't seem to get any errors, any ideas on what it could be?

  • I tried both, and turns out my converter was working all along but the strange thing was the order in which cables you connect firstwhich makes absolutely 0 sense to me, if i put rca before hdmi i would get no video through after connecting the hdmi first then video and both audios followed by the power i got an instant signal
