Hi, did you try playing a YouTube video with sound while you start streaming?

Hi, did you try playing a YouTube video with sound while you start streaming?

Hi, I did try now. It starts with screen frozen, then it speeds up and works fine after that. Thanks for workaround.

[mariotaku]

Hi, I have made a new release that doesn't need this workaround. Could you please try and tell me if they work for you?

[githubber321321]

Hi! Thank you for your quick response! It does work with stereo sound! Same issue exists with 1.6.17 with 5.1 sound.

[Matthias102]

Yeah, I have the same issue on a LG OLED65G39. Unless I start streaming with a fullscreen-app or youtube video active the screen immediatly freezes at startup.

[mariotaku]

@Matthias102 what's your setup, is it 5.1 surround or stereo, and which version did you install?

[mariotaku]

@githubber321321 I see, thanks for testing both modes! I'll try to improve the workaround so it can work for 5.1 surround too

[Matthias102]

I installed the Moonlight WebOS version 1.6.16. I haven't tried 5.1. , yet. The soundchannel is set to stereo.

Stats:
Videodecoder: ndl-webOS 5
Audiodecoder: ndl-webOS 5
LG OLED65G39
System webOS 8.3.0
Sound is passed to a single soundbar over HDMI

Videoencoder: NVENC by a RTX4080
Hostapp: Standardbuild Sunshine 0.23.1

I also run the android moonlight client on my samsung S24 Ultra and on my Firestick 4k Max (2021). Except from the HAGS-bug I don't have any issues with these client devices.

What's curious is that this freeze of the screen at the start of the stream isn't permanent. It will unfreeze as soon as there's an application that renders anything. And even if the applications stops running, the screen won't freeze again.

[githubber321321]

@Matthias102 Try the new version (1.6.17) it works fine for stereo mode. At least for me, it does.

Yes, I can confirm that. Unlike 1.6.16 it doesn't freeze with 1.6.17 in stereo mode at the start of the stream, but in 5.1 surround mode it does unless an app is actively rendering something.

[mariotaku]

Great stereo works for both of you! For the surround workaround, I was feeding 2.5ms of empty audio and I'll be trying longer sample

[Matthias102]

@mariotaku Thank you for the update

[mariotaku]

@githubber321321 @Matthias102 Hello! I have updated to use 5ms of blank audio instead of 2.5ms. Let's see if this snapshot works for you: https://github.com/mariotaku/moonlight-tv/actions/runs/9004094962

I'll increase until it works for both of you!

@mariotaku
I installed com.limelight.webos_1.6.17-f8cef72c_arm.ipk via web OS Dev Manager. Still freezes when set to surround.

[mariotaku]

@Matthias102 Thank you so much! How about this one?
https://github.com/mariotaku/moonlight-tv/actions/runs/9011506225
It now waits 40ms before playing

Sorry for the long delay... Couldn't take the time earlier to check it out!
1- https://github.com/mariotaku/moonlight-tv/actions/runs/9004094962
This one didn't work for me either...

2- https://github.com/mariotaku/moonlight-tv/actions/runs/9011506225
This one crashed a couple times, however it seems to be working fine, with no freezing whatsoever.

[mariotaku]

@githubber321321 Awesome! I think we're heading to the correct direction.

Could you please test this version again, to see if the sound works and having no crash? https://github.com/mariotaku/moonlight-tv/actions/runs/9041053555

[Matthias102]

@mariotaku I hope I am doing it the right way, but I still get a screenfreeze with com.limelight.webos_1.6.17-96b749ed_arm.ipk, when the client is set to surround.

This one froze too.

On a side note the app doesn't seem to crash anymore with build 2... The first couple times I ran it, it did crash on stream start. I can't reproduce it anymore.

I'm using auto for video and audio. Its setting to NDL video and audio, H265 and HDR on.

@githubber321321 @Matthias102 I'll try more different approaches, and using chat to speed things up. Would you mind finding me on Discord in Moonlight server?

Not at all. What channel should I Join. I appreciate your efforts!

[mariotaku]

I got a new snapshot, please let me know if it works for you: https://github.com/mariotaku/moonlight-tv/actions/runs/9044673457

@mariotaku
UUuhh nice, com.limelight.webos_1.6.17-a4845305_arm.ipk doesn't result in a screenfreeze on startup, when set to surround.

I might be a bit late, but I didn't have the issue described, it was instead frozen on boot after 1 frame was shown, then it automatically disconnected after a little while.

I can confirm that this build seems to have fixed it (no freeze so far). So I'm very glad to see this merged 😄

[mariotaku]

@francoislg Now that we have a confirmed working version, I have released v1.16.18 so everyone can get the update. Thanks for your testing :)
