FranceBB's LUT collection
by Andrew Randrianasulu 17 May '25

17 May '25

forum https://forum.doom9.org/showthread.php?t=176091 it says those LUTs should be usable for ffmpeg's lut3d and therefore for CinGG? github (each *.cube can be several mb's big) https://github.com/FranceBB/LinearTransformation author says they were verified on professional equipment... list includes PAL and NTSC variants for rec. 601....

I tried to add AVC-Intra 100 output profiles
by Andrew Randrianasulu 08 May '25

08 May '25

But not sure if I did this correctly. https://en.wikipedia.org/wiki/AVC-Intra says for AVC-Intra 100: AVC-Intra 100: nominally 100 Mbit/s, size of each frame is fixed CAVLC entropy coding only. All formats are High 4:2:2 Intra Profile, Level 4.1 4:2:2 chrominance sampling frames are not scaled and yeah, this French-language pdf actually says the same: https://web.archive.org/web/20110720215759/http://www.ficam.fr/upload/docum… 50M 100M Standard MPEG-4 part10 AVC/H.264 Profile High 10 Intra High 4:2:2 Intra Level Level 3.2/4.0 Level 4.1 Resolution 1440x1080 / 960x720 1920x1080 / 1280x720 Sampling 4:2:0 4:2:2 Bit rate 54Mbps 111Mbps Block size Y: 8x8, C: 4x4 Intra Prediction Y: 9mode, C: 4mode MBAFF Yes De-block filter No Slice/frame 10 Entropy coding CABAC CAVLC so, I looked up ffmpeg cmd line https://trac.ffmpeg.org/ticket/3597 ffmpeg -v info -i /mnt-data/backup4/vol0/export/CUHK\ 2014-1/V017b.mov -vcodec libx264 -intra -pix_fmt yuv422p10le -vb 100M -x264opts avcintra-class=100 -x264opts colorprim=bt709 -x264opts transfer=bt709 -x264opts colormatrix=bt709 -threads 4 -acodec copy V017b-ffmpeg-git-avcintra100.mov Huh, said I and entered those params in opts file, actually in two files (mp4 and mov containers) mov libx264 cin_pix_fmt=yuv422p10le flags -global_header keyint_min=0 x264-params=keyint=0:colorprim=bt709:transfer=bt709:colormatrix=bt709 avcintra-class=100 bufsize=100000000 level=4.1 mp4 libx264 cin_pix_fmt=yuv422p10le flags -global_header keyint_min=0 x264-params=keyint=0:colorprim=bt709:transfer=bt709:colormatrix=bt709 avcintra-class=100 bufsize=100000000 level=4.1 both for progressive content, for interlace you must add some more flags: https://lists.ffmpeg.org/pipermail/ffmpeg-user/2017-January/035049.html -flags +ildct+ilme -x264opts interlaced=1 Also, there is still lack of (GUI) user notification if file writing failed due to NO SPACE on device :} FFStream::write_packet: write packet failed. file:/dev/shm/avci_new.mp4 err: На устройстве не осталось свободного места FFStream::encode_frame: encode failed. file: /dev/shm/avci_new.mp4 err: На устройстве не осталось свободного места FFStream::flush failed :file:/dev/shm/avci_new.mp4 err: Операция не позволена Render::render_single: Session finished. ** rendered 273 frames in 85.585 secs, 3.190 fps Render::render_single: Session finished. ** rendered 273 frames in 85.485 secs, 3.194 fps Render::render_single: Session finished. ** rendered 273 frames in 82.176 secs, 3.322 fps Profile sort of assumes you set project to some supported resolution, framerate, etc, otherwise libx264 will fail with console error message..... I found some talk about AVC-Ultra, there even was patch for x264, but it was not merged: https://mailman.videolan.org/pipermail/x264-devel/2015-September/011412.html Also, I think sound must be uncompressed, but I'm not sure.

10bit VAAPI encoding test thread
by Andrew Randrianasulu 06 May '25

06 May '25

We branching! I looked at gpu-screen-recorder https://git.dec05eba.com/gpu-screen-recorder/tree/src/encoder/video/vaapi.c it sets AVHWFramesContext *hw_frame_context = (AVHWFramesContext*)frame_context->data; hw_frame_context->width = video_codec_context->width; hw_frame_context->height = video_codec_context->height; hw_frame_context->sw_format = self->params.color_depth == GSR_COLOR_DEPTH_10_BITS ? AV_PIX_FMT_P010LE : AV_PIX_FMT_NV12; hw_frame_context->format = video_codec_context->pix_fmt; hw_frame_context->device_ctx = (AVHWDeviceContext*)self->device_ctx->data; so may be we need to set AV_PIX_FMT_P010LE and not just P010?

I tried to make Appimage out of cinHV!

Is anyone brave enough to test it? :) commit a30bb38bcdb6fe1fabdb534611bc2b9123f70514 (origin/master, origin/HEAD) Author: heroineworshiper <broadcast(a)earthling.net> Date: Thu Oct 10 21:56:45 2024 -0700 + some of my patches (can resend separately)

Two patches hopefully fixing build on NetBSD 10.0/amd64
by Andrew Randrianasulu 18 Dec '24

Currently from that system I still need to set export LD_LIBRARY_PATH="/usr/pkg/lib/ffmpeg6" and set audio output to oss - > /dev/audio but it seems to work. Can you check them by building on Linux? :)

I've tried several tests, but I can't get to the bottom of the problem. On my system I have the following packages involving OpenGL: freeglut 3.6 glu 9.0.3 glslang 14.3 libepoxy 1.5.10 libglvnd 1.7 qt6-shadertools 6.7 and mesa 24.2.3 xf86-video-amdgpu 23.0.0 (for the 2D and opengl) I also have the same errors in Wayland (which, I imagine, uses xwayland) however I have better performance in timeline and no crashes. I too think it is some mesa update or, even more likely, amd drivers. However the problem is not only in the latest CinGG release but also in the previous one and also in a different distro (however always rolling and Arch based).

Mesa 24.3 and Vulkan
by Terje J. Hanssen 15 Dec '24

15 Dec '24

In August this year we had a thread "h264 vulkan encoding" initiated by Andrea https://lists.cinelerra-gg.org/pipermail/cin/2024-August/008517.html Mesa 24.3 is released with many Vulkan Driver Improvement, and implementations are expected around the corner in rolling distributions. Some articles about this in Phoronix https://www.phoronix.com/news/Mesa-24.3-Released https://www.phoronix.com/news/Mesa-24.3-rc2 https://www.phoronix.com/news/Mesa-24.3-rc1-Released https://www.phoronix.com/news/Intel-Vulkan-Video-H264-H265 With ffmpeg (7.1) h264/5 vulkan encoder support, I wonder if Cingg is ready to put them into use? ffmpeg -hide_banner -encoders | grep vulkan V....D h264_vulkan H.264/AVC (Vulkan) (codec h264) V....D hevc_vulkan H.265/HEVC (Vulkan) (codec hevc)

OT: GPU-Viewer - A GUI front-end to glxinfo, vulkaninfo, clinfo and es2_info.
by Terje J. Hanssen 02 Dec '24

02 Dec '24

/"This project aims to capture all the important details of glxinfo, vulkaninfo and clinfo in a GUI. The project is being developed using python 3 pygobject with GTK4. All the important details are extracted using glxinfo/vulkaninfo/clinfo with the combination of grep, CAT , AWK commands and displayed in the front-end. There is no hard OpenGL Programming involved, until glxinfo, vulkaninfo and clinfo works the GPU-viewer will also work" /https://github.com/arunsivaramanneo/GPU-Viewer https://arunsivaramanneo.github.io/GPU-Viewer/ https://linux.softpedia.com/get/System/Monitoring/GPU-Viewer-104591.shtml There are DEB based and Arch packages. Thanks to malcolmlewis at openSUSE Build Service who has build it for Tumbleweed/Slowroll.
