BUG [CLOSED] TVheadend client choppy, when activating external grabbing

Hi Girls&Guys!

I found a Bug, which breaks HW-decoding of TV-channels under CoreElec 9.2.2
(full discussion of the issue and logs/samples can be found here: https://discourse.coreelec.org/t/tvheadend-choppy/10574/23)

VERDICT >> FOUND the issue-maker: as soon as an EXTERNAL USB-GRABBER is activated in Hyperion.NG, the stutering / choppiness starts (fushicai utv001, not plugged in!).
==> Deactivating the external grabber instantly fixes the TV-channels not being decoded in hardware!

Now - to the solution ?

 

bump

 

?
under 9.2.3 /dev/video0. appears but it's not grabbing anything - so,.. somehow it only get's worse from update to update :-(

 

Another Take:

- Clean install of CoreElec 9.2.4.2
- Clean install of Hyperion.NG addon
- Clean install of TVHeadend Server + Client + Oscam.
(Did NOT copy ANY files from a backup)

- Configured it ALL from Scratch!

--> activated USB-Grabber with prio 230 ( internal grabber is 250/default)

after 3rd reboot, video-device for decoding TV is not available and only SW-decoding is available, which renders all CPUs to 100% !
