SOLVED: [softhddevice / va-api-egl + Alder Lake-N]: green screen with certain live streams

carel · November 12, 2025 at 3:15 PM

Hello lnj

I'm testing a new N100 board with "Intel Corporation Alder Lake-N" GPU

I can run cable channels (1080i) fine, the problem is with live streams..

Sound is there but there's either no video or a green screen. I'm seeing below in the logs + flooding of "video/vaapi: vaSyncSurface failed"

vdr-2.7.7 / ffmpeg: 7.2.1 / softhddevice: latest from git

I made a recording: http://www.nekanali.nl:8020/VTM-green-screen.tgz

Maybe fixing this is all too difficult, then I'll re-mount my Nvidia 1080

What Intel driver?

Are you sure, -v va-api-egl, looks like va-api-glx.

Post the all log.

carel · November 13, 2025 at 11:09 AM

I run with:

-P"softhddevice -d :0 -v va-api-egl -a hw:0,3 -w alsa-driver-broken -w alsa-close-open-delay -w still-hw-decoder"

I also tried va-api-glx, but this fails to show a picture together with flooding messages: video/glx: vaCopySurfaceGLX failed

Thanks!

Need a log from the start of vdr, when softhddevice was initialized.

You can try:

export LIBVA_DRI3_DISABLE=1

or the opposite add in xorg.conf

Option "DRI" "3"

Also, try other Intel driver.

carel · November 14, 2025 at 9:03 AM

I can't use driver 'intel' in xorg.conf. X won't start and the driver 'modesetting' ignores the option DRI

I have another VDR client with older mesa/egl packages running the same VDR without issues. (same libva and intel drivers, but the GPU is a JasperLake)

Some changes in mesa must have broken things.

Maybe the attached startup log helps

Just to tell this has been solved I was running X and my TV on 60Hz all the time, that seems to cause black and/or green screen for some live-streams (with 25 fps..)

Now with 50Hz it looks good
