Flickering / unable to grab image when using HDMI sources

[LegendaryB]

The goal was to be able to capture HDMI sources for hyperion.
This resulted in a slow TV (lag), flickering and fragments all over the capture (image)

Command
LD_LIBRARY_PATH=. ./hyperion-webos --address 192.168.178.41 --port 19400 --backend libdile_vt --width 320 --height 240 --fps 10

Got the same issue with PicCap.

[PinkyJie]

Hey @LegendaryB, I just realised our system information are almost the same, but mine got very lower FPS when using libdile_vt.

Fixed for me with the following pull request: #34
At the moment I'm on the latest webOS, Piccap 2.2 and rooted via RootMyTV v2

[PinkyJie]

Thanks for letting me know @LegendaryB, the combination works to me as well!

[LegendaryB]

@PinkyJie Great to hear that 👍

[Informatic]

Whenever (any of) you have time, please fill out your system info in #16 and we'll close this issue :)

[PinkyJie]

@Informatic updated my info there, thanks!

[LegendaryB]

@Informatic Added missing information. I close this ticket. Many thanks again :)
