Ah, no vaapi-vulkan interop on gfx8!
by Andrew Randrianasulu 26 Apr '25

Feature request: https://gitlab.freedesktop.org/mesa/mesa/-/issues/11074 https://gitlab.freedesktop.org/mesa/mesa/-/issues/5882 found via this post on reddit: https://www.reddit.com/r/jellyfin/comments/y7zns9/vulkan_filtering_on_amd_v… ==== However, there are still some limitations from upstream. First of all, the essential Vulkan extension *VK_EXT_image_drm_format_modifier* is currently *only available on Vega and newer cards/gfx9+*, which means that Polaris and older <https://gitlab.freedesktop.org/mesa/mesa/-/issues/5882> users will need to wait until upstream to complete the extension before they can get support for this. In addition, DRM changes are involved, so the Linux *kernel requires 5.15+*. ====

Hello, It's been a quite a while that I receive only the mails from Sam via Cin. Somethings wrong or this is the new normal ? :) Greetings and thanks for your work you all :) Haldun.

cingg faster than ffmpeg itself on pulling frames!?
by Andrew Randrianasulu 26 Apr '25

26 Apr '25

I tried to bench simple ffmpeg command (ffmpeg 7.1.1): time -p ./ffmpeg -hwaccel vaapi -i ~/K38_sdcard1/Documents/iPhone11_4K-recorder_59.940HDR10.mov -c:a copy -c:v rawvideo -f nut /dev/null this benches for 4k 60 fps HDR video at frame= 1148 fps= 10 q=-0.0 Lsize=27900063KiB time=00:00:19.16 bitrate=11927607.4kbits/s speed=0.173x real 111.77 user 42.61 sys 119.01 10 fps,150% cpu load. ffmpeg 4.4 was using just 85% cpu but only managed frame= 1148 fps=8.5 q=-0.0 Lsize=27900063kB time=00:00:19.15 bitrate=11933560.4kbits/s speed=0.142x 8.5 fps. But I am fairly sure I saw *15* fps in cingg on same file , if you set "play every frame" and vo driver to x11. Anyone want to repeat this experiment? Is it artefact of running 32bit program on top of 64bit kernel? At some point I might try latest Fedora 42 to see if full 64bit Linux will pull more frames out of same gpu decoder on same motherboard

Techblog on HDR from Netflix perspective (2018)

https://netflixtechblog.com/enhancing-the-netflix-ui-experience-with-hdr-1e… referenced in https://www.collabora.com/news-and-blog/news-and-events/breakthroughs-open-… technically, cinelerra does have pop up menu in fullscreen (compositor/viewer) mode, but I guess caring about it being correctly blended into HDR image is one of our least worries .....

HW Accel
by Andrea paz 26 Apr '25

26 Apr '25

A few silly questions on topics already addressed several times. I was reading about hardware acceleration in ffmpeg. In my system ffmpeg I have: $ ffmpeg -hwaccels ffmpeg version n7.1 Copyright (c) 2000-2024 the FFmpeg developers built with gcc 14.2.1 (GCC) 20250207 configuration: --prefix=/usr --disable-debug --disable-static --disable-stripping --enable-amf --enable-avisynth --enable-cuda-llvm --enable-lto --enable-fontconfig --enable-frei0r --enable-gmp --enable-gnutls --enable-gpl --enable-ladspa --enable-libaom --enable-libass --enable-libbluray --enable-libbs2b --enable-libdav1d --enable-libdrm --enable-libdvdnav --enable-libdvdread --enable-libfreetype --enable-libfribidi --enable-libglslang --enable-libgsm --enable-libharfbuzz --enable-libiec61883 --enable-libjack --enable-libjxl --enable-libmodplug --enable-libmp3lame --enable-libopencore_amrnb --enable-libopencore_amrwb --enable-libopenjpeg --enable-libopenmpt --enable-libopus --enable-libplacebo --enable-libpulse --enable-librav1e --enable-librsvg --enable-librubberband --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libsrt --enable-libssh --enable-libsvtav1 --enable-libtheora --enable-libv4l2 --enable-libvidstab --enable-libvmaf --enable-libvorbis --enable-libvpl --enable-libvpx --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxcb --enable-libxml2 --enable-libxvid --enable-libzimg --enable-libzmq --enable-nvdec --enable-nvenc --enable-opencl --enable-opengl --enable-shared --enable-vapoursynth --enable-version3 --enable-vulkan libavutil 59. 39.100 / 59. 39.100 libavcodec 61. 19.100 / 61. 19.100 libavformat 61. 7.100 / 61. 7.100 libavdevice 61. 3.100 / 61. 3.100 libavfilter 10. 4.100 / 10. 4.100 libswscale 8. 3.100 / 8. 3.100 libswresample 5. 3.100 / 5. 3.100 libpostproc 58. 3.100 / 58. 3.100 Hardware acceleration methods: vdpau cuda vaapi qsv drm opencl vulkan If I try the same command with ffmpeg contained in .../thirdparty/ffmpeg-7.0 I get: ./ffmpeg -hwaccels Hardware acceleration methods: vdpau cuda vaapi vulkan So I guess OpenCL; Qsv and drm can only be obtained by manually compiling them. With what exact options in ./configure? (I never know when to use “--with-” and when to use “--enable-”). “drm” can serve in CinGG? Another thing: vulkan is already included in CinGG, but I have never been able to activate the device and get it working. How to do that? With system ffmpeg I can activate it without any problems. I am attaching the part of ffmpeg's documentation regarding hardware acceleration. The following part (regarding decoding) seems important to me: "Note that most acceleration methods are intended for playback and will not be faster than software decoding on modern CPUs. Additionally, ffmpeg will usually need to copy the decoded frames from the GPU memory into the system memory, resulting in further performance loss. This option is thus mainly useful for testing." As usual, I thought it would be a good thing to have playback in hardware but it is not. (However, there is a video of Adam where he manages to get better decoding with his Nvidia: https://www.youtube.com/watch?v=IZdJqrObnik)

HDR10 on radeonsi/EGL
by Andrew Randrianasulu 26 Apr '25

interesting bug report I found. https://gitlab.freedesktop.org/mesa/mesa/-/issues/12669 "radeonsi: Cannot deliver HDR10 0.0-125.0 values to 16 bit float GBM surface, only 0.0-1.0 seems to work. " So, it sort of force-normalized at least in egl ?

OpenCL on CPU
by Andrew Randrianasulu 25 Apr '25

25 Apr '25

note, openCL is different to openGL, mostly being more about more accurate computations. On AMD FX4300, 32bit userspace but llvm probably uses avx? guest@slax:/dev/shm/mesa/BUILD$ RUSTICL_ENABLE=llvmpipe clpeak Platform: rusticl Device: llvmpipe (LLVM 20.1.3, 256 bits) Driver version : 25.2.0-devel (git-845611bb43) (Linux x86) Compute units : 8 Clock frequency : 300 MHz Global memory bandwidth (GBPS) float : 3.72 float2 : 4.08 float4 : 3.59 float8 : 2.81 float16 : 2.09 Single-precision compute (GFLOPS) float : 14.67 float2 : 17.86 float4 : 15.99 float8 : 14.72 float16 : 14.63 No half precision support!

Biggest obstacle for me was that mesa git require some new llvm, and just released two days ago SPIRV-Tools-2024.4 ! And github "release" is of course broken, in sense you need to manually fetch headers at specific commit. Of course "real gpu" will get like >200 GFLOPS , even my puny GF710 was that fast, but possibility of lock up makes this option less attractive ;)
