Bug Description

Moonlight on WebOs was working properly until recently the tv updated. Since then either with the moonlight or Steam app there is a black screen every time i tried to stream my pc. I tested on my iphone and other computer and it works fine but it’s not working on my LG tv. Tried with different configurations of the video decoder and audio backend. There’s still the black screen with any config, and audio works only when i select any other source beside WebOS NDL, if I set NDL audio also dissapear

Reproduction Steps

No response

Expected Behavior

To LG tv show my pc streaming through moonlight properly as it happen before the update

@DanO83 Hi, would you mind sharing the software version & model of your TV? Sounds like we're having a pattern...

go to settings > video settings and make sure "Use H265 when possible" is not checked

Same issue here, but it was the first time I tried moonlight-tv, so couldn't tell it was a new bug.
And disabling H.265 fixes the issue 😓.

Are you all Having an AMD GPU? This looks like a pattern to me...

[mostafa0017]

@davlenx When you said black screen while streaming either with the moonlight or Steam app what exactly did you mean? what was the streaming server and corresponding client when you tried streaming via Steam ?

Same issue and I have AMD GPU.
Using sunshine for streaming:

If i use AMF encoder i get black screen in h265
If i use software encoder all work in h265

So I have a similar issue and did some testing. All tests done with WebOS NDL option.

Sunshine AMD encoder + TV only AV1:
= Image completely freezes after few minutes of gameplay but audio is still there.

Sunshine AMD encoder + TV only H265:
= Black screen but audio is there.

Sunshine Software encoder + TV only AV1:
= No AV1.

Sunshine Software encoder + TV only H265:
= Automatically selects H264. (FPS drops to 50 from 60 when 4K, but fine with 1440p, also very high latency)

Sunshine Intel Quicksync + TV only AV1:
= Image completely freezes after few minutes of gameplay but audio is still there.

Sunshine Intel Quicksync + TV only H265:
= Black screen and no audio.

Sunshine AMD encoder + TV H264:
= Now this is the best one so far. Has very low latency and also can keep stable 4K 60FPS. However, though there is no frame drop, games feel like 50-55 FPS. I see some micro stuttering, similar to this post. Turning off or on the Vsync / Lowering the bitrate did not help. Games are still playable with distance from TV.

My Specs:
i5-13600K
RX 7900 XT
1000/120 internet speed. Using ethernet for both host and client.
