Hi hyperion users!

i’m a new hyperion user. currently i’ve got some problems where capture card isn’t displaying an image through hyperion web ui. leds are working as i can do the effects.

using a fire stick 4k into a pioneer avr then hdmi splitter and capture card into the pi.

using a pi3b

okay, use only 1 channel MAIN HDMI out on AVR. (deselect output 2 if available)

connect the splitter to that channel, set on Auto not Copy mode.

then main TV on output channel 2

then the loop grabber hdmi cable on channel 1.

usb to Raspi 3b.

and put the log here >> debuglog with expertsettings level

RE: Black image from capture card

[…]

If the grabber produces a black image, it is likely that the the brightness is set to zero.

To get this corrected:

a) Switch to Expert Setting
b) Check the Control values (see 1.)
c) Press Button "Default Hardware controls" (2.)

d) The Control Values should have changed (3.)

hyperion-project.org/index.php?attachment/8036/

e) Click Save (4.)

Would be great, if you could report back, if that worked.

I updated the Release notes to ensure that people can…

and review the grabber‘s hardware control settings.
