System ffmpeg Vulkan video transcoding fails - while benchmarking works
by Terje Hanssen 26 May '25

26 May '25

I have yet to get my system ffmpeg vulkan video transcoding to work on my machines, while benchmarking works. Therefore I hope get verified if my code line is correct, and how to fix possible syntax errors. ----------------- Dell XPS 13-9370 ultrabook ffmpeg version 7.1.1 built with gcc 14 (SUSE Linux) inxi -CGSz System: Kernel: 6.12.24-1.0.2.sr20250402-longterm arch: x86_64 bits: 64 Desktop: GNOME v: 48.0 Distro: openSUSE Tumbleweed-Slowroll 20250402 CPU: Info: quad core model: Intel Core i7-8550U bits: 64 type: MT MCP cache: L2: 1024 KiB Speed (MHz): avg: 900 min/max: 400/4000 cores: 1: 900 2: 900 3: 900 4: 900 5: 900 6: 900 7: 900 8: 900 Graphics: Device-1: Intel UHD Graphics 620 driver: i915 v: kernel Device-2: Realtek Integrated_Webcam_HD driver: uvcvideo type: USB Display: wayland server: X.org v: 1.21.1.15 with: Xwayland v: 24.1.6 compositor: gnome-shell driver: gpu: i915 resolution: 3840x2160~60Hz API: OpenGL v: 4.6 vendor: intel mesa v: 25.0.3 renderer: Mesa Intel UHD Graphics 620 (KBL GT2) API: Vulkan v: 1.4.309 drivers: N/A surfaces: xcb,xlib,wayland API: EGL Message: EGL data requires eglinfo.

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.

BlendAlgebra plugin and cc="ccache gcc"
by Andrew Randrianasulu 06 May '25

06 May '25

I tried to rebuild cingg Slackware package with my custom Slackbuild and noticed that BlendAlgebra breaks if I left out initial line from year 2016 cc="ccache gcc" it seems that ccache breaks with unknown (for it) arguments like -noabi. Commenting this line from Slackbuild fixed it for me. At some point mass package building was done with ccache, but now probably only two Appimages build manually, so this error was unnoticed.

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?

Updated AppImages for April 2025
by Phyllis Smith 30 Apr '25

30 Apr '25

There are now updated AppImages, Release Notes, and PDF/HTML manuals on the website and Andrey's packages are up to date at: https://github.com/einhander/cin-gg-packages/releases Release notes included below with some concern for the Speed mod as noted with no real concern for Blur and Titler. *GIT for Cinelerra-GG has the following changes from 04/01/2025-04/302025* *Blend Algebra and Blend Program plugins:* An additional SYSLIB Blend Program of tone_mapping.bp has been created by *Andrea* for tonemapping an HDR media and report its values within the range (0, 1.0). For usage, reference Example 6 in the file at: https://cinelerra-gg.org/download/testing/BlendPluginExamples/Examples.txt For netBSD, modifications were added by Andrew to fix shebang-perl and to not use ldl in Makefile. *Other small changes include:* 4.0 cmake requires 3 patches that *Andrew* has provided and Andrea had discovered/tested on Arch for x265 and libsvtav1. A speed bug has been found and was described reproducibly by *Lukas*. A one line change to auto.C seems to fix it, but it is unknown if reverting that line will lead to a previously diagnosed problem reoccuring. The old version of ffnvcodec (Video codec SDK) which was 10.0.26.0 was added back to the source as ffnvcodec-old.tar.xz to accommodate versions before the updated version of ffnvcodec for 12.2.72.0 was installed as the default. Blur and Titler plugins were modified so that these plugins can be used in combination with others (e.g. Blue Banana) without introducing the clipping into the process. Andrew provided the mod and Andrea tested it to ensure it worked without clipping and IgorB tested to make sure there was no impact to current usage of Blur and the Titler. Tiff was updated from 4.6.0t to 4.7.0.

xavc-intra class 480
by Andrew Randrianasulu 28 Apr '25

28 Apr '25

In attempt at speeding up hdr10 4k HEVC video playback I tried to re-encode it into AVC-intra using this guide: https://www.voukoder.org/forum/thread/1163-replicate-sony-s-xavc-i-s-format/ basically either ffmpeg -i input -c:v libx264 -avcintra-class 480 -pix_fmt yuv422p10le -preset ultrafast -x264opts avcintra-flavor=sony -c:a pcm_s24le -ar 48k output.mxf or for half size ffmpeg -i ~/K38_sdcard1/Documents/iPhone11_4K-recorder_59.940HDR10.mov -s 1920x1080 -c:v libx264 -avcintra-class 200 -pix_fmt yuv422p10le -preset ultrafast -x264opts avcintra-flavor=sony -c:a pcm_s24le -ar 48k output-half.mxf Note, line errors out when I tried class 480 for 1920x1080 frame size Both files load into cingg Original file (4k hdr hevc, 59.94 fps) plays at around 22 fps at output x11, project rgba-float. But seeking is sad. Not to mention lack of tonemapping. First 4k avc-intra 4k reencode plays at around 33 fps and seeks much better (no artefacts) 1920x1080 proxy plays at 60 fps, and if I check play every frame and try 2x speed forward - at 83 Fps. But trying two FullHD tracks referencing same "proxy" file set to different fade leves with project set to RGBA-float kills fps back to 2-3 :) Encoding at ultrafast preset was 4.5 fps for 4k version and 12 fps for FullHD version. Filesizes: du -h *.mxf 1.0G output-half.mxf 2.2G output.mxf this is just for frame= 1149 time=00:00:19.15 Well, I guess without some serious GPU upgrade this machine not gonna play HDR 4k :) Regular 8 bit/SDR 4k somewhat plays in firefox (if file just av1, 24 fps), at least on Linux where I can set GPU frequency a bit higher than default on nouveau/libre drivers.

I tried to make sws_scale go multithread ..
by Andrew Randrianasulu 28 Apr '25

28 Apr '25

BUT FAILED. in sense my mod apparently just leaks (swsContext?) so it can't play even 20 sec of 1440*1080 video to completion in termux, running on tablet with 3Gb ram. There seems to be difference if I set thread count manually (on file reading only for now) but it looks negative, in other words higher thread count -> slower total playback .. tried 8, 4,1,16 on 8 cpu tablet. Speed was going down from 18 fps for unaltered cingg to 13 with 8 threads and crash/oom with 16 ;) And if I try to use sws_scale_frame I just got all blank/black frames on timeline .... I think switching to sws_scale_frame is important if we want to try new colormanagement support in ffmpeg.git ... Resources used, apart from that Blender diff: https://github.com/mltframework/mlt/blob/master/src/modules/avformat/filter…
