Stream flashes with H264 and hangs with H265

[trubesv]

Hello, first of all thank you for all the work around Shadow :)

Describe the bug 2 different behaviours, whether "Low bandwidth mode" is ticked or not in the Shadow options, which toggles H265 encoding. Same behaviours for each, whether "Fullscreen on start" is ticked or not.

• H264, "Low bandwidth mode" not ticked: Stream hangs a few seconds on a black screen when starting, then flashes continuously and rapidly between a black screen and what is under the Shadow window (desktop, browser, ...)

• H265, "Low bandwidth mode" ticked: Stream hangs a few seconds on a black screen when starting, then gets stuck on the first frame displaying the Shadow desktop, no visual feedback expect for the mouse movement and pointer. Mouse input seems to work since the pointer changes when hovering different elements, and actions can be performed (open folder, right click, ...)

Configuration

• The environment uses Xorg ?

  Yes

• VA API detects H264 ? And H265 ?

  See below

Additional context

• https://nicolasguilloux.eu/hostbin/2950202789
• vainfo output seems to be missing a few lines
• Discrepancy between vainfo & check_script.sh for H265 support
• Similar behaviour than https://github.com/NicolasGuilloux/blade-shadow-beta/issues/13
• No issues with https://parsecgaming.com when used to check if inputs were registered
• Deepin is a very fancy desktop environment so could it be related to a compositing issue?

Thanks for your help :)

EDIT: I just tried with compositing off, kind of the same behaviours:

• H264 hangs on a black screen, it's not flashing anymore
• H265 hangs on a black screen as well but with a green bar from left to right at mid height. Shadow overlay is displayed though but I can't interact with it. Mouse inputs still registered but no visual feedback.

Hey it seems your machine doesn't support H265, what's your CPU exact model ?

Hi, its an i7-4600U, with 4400 igpu

I tried with the alpha AppImage and still have the same issue Also, shadowcker doesn't seem to start, see https://pastebin.com/4i6J51nH

EDIT: Shadowcker does start after running the xhost +localhost ; xhost +local:docker commands
