[hyperiond V4L2:] (ERROR) Throws error nr: Cannot identify '' error code 2, No such file or director

  • Hi all,


    I am facing a strange problem, my hyperion.ng setup was runing all fine.
    The setup is running as follows on a RPI3 (no +), Raspbian with Kodi and I am using internal video grabbing and the STK1160 as a external video grabber for PS4 and other HW.
    Both sources were running fine in the past, but now only internal grabbing is working, external grabbing is no longer possible. Neither I see a screen in the WebGUI-Screen-Capture-Preview nor are the LEDs active.


    Hyperion.NG log on the Webside says the follwing:

    Any suggestions how I can trace down the problem?
    Thanks for any support

    I saw you did some changes on your git repo and also saw your posts here: https://hyperion-project.org/t…olution-issue.3684/page-2


    I cloned you v4l2fix branch to see if it may fix my issue, but it doesn't. :(


    But two observations I have for which I would need clarification:
    - Starting the new compiled hyperion I am still able to use my "old" password. Are there some system wide shared config files for all hyperion instances?
    - Going trough the log I do still get the same error message and the same layout of the log. But in the above mentioned post you said there shouldn't be a new line after the list of the devices. Is this still valid? Or did you undo this change on the latest branch?


    Thanks for any support.
