FranceBB's LUT collection
by Andrew Randrianasulu 16 May '25

16 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'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).

New SVT-AV1 release: v2.3.0 from AOM
by Terje J. Hanssen 05 Nov '24

05 Nov '24

As seen on reddit, the Alliance for Open Media - AOM has released SVT-AV1 v. 2.3.0 The Scalable Video Technology for AV1 (SVT-AV1 Encoder) is an AV1-compliant software encoder library. * NEW FAST DECODE MODE * New fast-decode (2) to allow for an average AV1 software cycle reduction of 25-50% vs fast-decode 0 with a 1-3% BD-Rate loss across the presets * Improved fast-decode (1) option to increase its AV1 software cycle reduction by ~10% while maintaining the same quality levels * Improved --lp settings for high resolutions, with CRF gaining a ~4% improvement in speed and VBR gaining ~15% * Further Arm-based optimizations improving the efficiency of previously written Arm-neon implementations by an average of 30% * Address speed regressions for high resolutions first pass encode by tuning the threading parameters, with 1080p showing the biggest gains * Enabled AVX512 by default in cmake allowing for ~2-4% speedup * ...and more https://gitlab.com/AOMediaCodec/SVT-AV1/-/releases/v2.3.0#230---2024-10-28 https://gitlab.com/AOMediaCodec/SVT-AV1/-/blob/master/README.md?ref_type=he…

VAAPI supported Encoding formats
by Terje J. Hanssen 03 Nov '24

03 Nov '24

In hope it may be of some use for Cingg next, I make a summary and supplement to the guide in https://trac.ffmpeg.org/wiki/Hardware/VAAPI#Encoding And instead of adding a tail to already too long recent threads, I start a new thread here. Two additional references are used Developer Reference: Media Capabilities Supported by Intel Hardware https://www.intel.com/content/www/us/en/docs/onevpl/developer-reference-med… Supported Encoding Input Format and Max Resolution https://github.com/intel/media-driver/blob/master/docs/media_features.md#su… to clarify the Encode Features for my own Intel Arc A-series Discrete Graphics HEVC (fixed-function hardware + shader-based) 8-bit, 4:2:0 (NV12) 10-bit, 4:2:0 (P010) 8-bit, 4:2:2 (YUY2, Windows only) 10-bit, 4:2:2 (Y210) AV1 8-bit, 4:2:0 (NV12) 10-bit, 4:2:0 (P010) A short reminder: 8-bit vs 10-bit color depths is 256 vs 1024 color levels of each RGB color, or 16.7 mill. vs 1.0 bill colors. 4:2:0 vs 4:2:2 color sub-sampling is keeping 1/4 vs 1/2 of all 4:4:4 colors or the precision of color compression. https://fujifilm-x.com/en-us/series/the-filmmakers-handbook/8-bit-or-10-bit… An important point to notice is that the VAAPI encoding 'formats' are based on those in the parentheses () above. Three simplified ffmpeg code lines with default bit-rates and without audio are used in the following three examples. Resulting fps encoding counts or speeds are the same in all cases; I don't know why.
