Failure to encode video frame on AMD RYZEN AI MAX+ 395 w/ Radeon 8060S

[talpadk]

Description

When the HMD connects to the alvr server it sometimes displays a dark flat square with the steamvr landscape. But it never starts streaming the a functional VR environment.

ALVR also opens two small windows that complain about it not being able encode the video frames (I do wonder where the App on the HMD gets that initial image from if the video encoding fails)

From the logs "tab":

General Troubleshooting

• [ x] I carefully followed the instructions in the README and successfully completed the setup wizard
• [x ] I read the ALVR GitHub Wiki

Added the launch option for steamvr:

/home/talpa/.local/share/Steam/steamapps/common/SteamVR/bin/vrmonitor.sh %command% according to https://github.com/alvr-org/ALVR/wiki/Linux-Troubleshooting

My best guess at the location that emmits the error:

alvr/server_openvr/cpp/platform/linux/EncodePipelineVAAPI.cpp 395: throw alvr::AvException("av_buffersrc_add_frame failed", err);

Environment

Sway as the window manager (wayland protocol)

SteamVR Version: 2.12

Install Type: tar.gz and I also tied to compile alvr_streamer from source

OS Name and Version Debian GNU/Linux forky/sid

[talpadk]

Also all 3 AMD encoder tests at the bottom of https://github.com/alvr-org/ALVR/wiki/FFmpeg-Hardware-Encoding-Testing works just fine and produces video files while slightly loading the gpu

[talpadk]

If I simply return in

alvr/server_openvr/cpp/platform/linux/EncodePipelineVAAPI.cpp 395: throw alvr::AvException("av_buffersrc_add_frame failed", err);

instead of throwing the error alvr seems to be working fine.

I haven't tried to count the number of time it happens to se if it just a single frame it happens to yet.

[shenmintao]

I'm experiencing the exact same issue. The log shows the same av_buffersrc_add_frame failed error on AMD RYZEN HX370

[dgleaton03]

Same issue here on Ryzen HX 370 and 6700XT.

[tisDDM]

Same here. Is there any bugfixing going on already? @talpadk Could edit be a workaround? Would everything be working fine?

[talpadk]

We probably should count the times it occur (might leak memory or something else), maybe write a message to stdout or stderr But I suspect that it is only the first frame that the encoder frame that fail. It may also cause a delay of one frame in the video signal, but I would think that the headset simply displays the most recent frames it gets

But at least for me it allows me to use alvr and I don't see any bad side effects here

[Wurztha]

Same issue here on same hardware as talpadk but using Bazzite 43 what do you mean by "If I simply return in" as I can't get to use ALVR at all?

As I mentioned earlier, I haven't looked into if this leaks memory, or if it happens more than once. But at least it made ALVR work for me.
