Ubuntu heavy lags

[Barmallini]

Description

Lags in transcoding Server was build with: cargo xtask build-server --no-nvidia --bundle-ffmpeg --release Client was build with alvr_build_linux.sh With h264 it'l lags heavily - check attached screen

With h265 no lags in statistic window, but picture in Oculus consist of random square artifacts (like old broken MPEG movie)

Also, ffmpeg give: ALVR$ ffmpeg ffmpeg: symbol lookup error: /usr/lib/x86_64-linux-gnu/libSDL2-2.0.so.0: undefined symbol: wl_proxy_get_tag

General Troubleshooting

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

RX580 has VERY SLOW h.264 encoder and before 5.17 kernel it configured to work much slower (maybe even slower than software) Try encode with 265 or install git kernel version. I not tried use rx580 after polaris performance fix, so i do not know if it really would be faster in this case. For me 0.7 resolution and 80fps worked good in non-heavy games on 265 after disabling rate control (remove rc_mode option from EncodePipelineVAAPI)

Kernel fix for h.264: https://www.phoronix.com/scan.php?page=news_item&px=AMD-VCE-Better-Speed It os not ALVR issue

This shots with HEVC One from Oculus (garbage), second from statistic

[mittorn]

It looks like it failed to create vaapi encode pipeline (software hevc encode seems to produce garbage on quest)
