I have forked the repo and made the necessary changes for moonlight to compile. AMLogic support is already included in the Vero 4K.

Is someone willing to check what might be wrong? Thanks

I'm bumping this and adding more logs:

Hope that someone will look into this sooner or later ;)

Can you try specifying the target audio device manually?

If that fails, try building with PulseAudio to see if the PA backend works.

[TheHacker66]

Hi @cgutman!

Thanks for the suggestions, specifying the audio works (kinda), i can hear crackling sounds coming from the tv but the video is still black.

Something interesting coming from the verbose output:

What exact parameters are you passing to stream? What GPU is in your PC?

You might try adding -codec h264. I found that some Amlogic chips don't like the default h.265 stream that GeForce Experience produces.

I implemented a workaround in moonlight-common-c for the most recent GFE version, which supports specifying the number of reference frames. moonlight-stream/moonlight-common-c@f6ae7fc

[TheHacker66]

The last time I simply ran moonlight stream -audio hw:0,0 -platform aml. I have a GTX 770.

I merged the recent commits, I'll compile, test using your suggestions and report back tonight. Thanks!

[TheHacker66]

Unfortunately specifying the h264 codec didn't change much, i got less errors in console but the screen is still black.

[TheHacker66]

OSMC and Vero 4k were updated to Stretch. Unfortunately the black screen issue still remains.

Can you try run strace and see if it gives us anything useful?

[TheHacker66]

Yup, here's the log: https://paste.osmc.tv/isavozohoz

Hello,

I belibe this is a kodi and amlogic problem and not with moonlight.

Please take a look here:
https://forum.odroid.com/viewtopic.php?f=91&t=15456&p=171714&hilit=%2Fsys%2Fclass%2Fvideo%2Fdisable_video#p171714

try to set /sys/class/video/disable_video to 0 before starting moonlight

[samnazarko]

Good find @danielfmo . Let us know how it goes @TheHacker66 .
I can patch Kodi to reset this on exit; or you can set it in a startup script in Moonlight.

[TheHacker66]

Well guys, unfortunately setting that flag before running moonlight didn't change anything. I can run another strace with the flag set to 0 if needed.

So close yet so far..

[samnazarko]

@TheHacker66 I've sent you a PM with a kernel with amlvideo debugging on. It may give us some clues if the decoder isn't happy.

[TheHacker66]

I won't be at home till Saturday, so I'll test it once I get back.

[samnazarko]

Cool. I found why HEVC wasn't tolerated by Moonlight (buf margin needs a bump). This also fixed a couple of playback issues.
