bug 674 (nested edl crash)
by Andrew Randrianasulu 08 Mar '26

08 Mar '26

Look for file named 0001-EXPERIMENTAL-better-fix-for-nested-edl-load-undo.patch* It fixed crash I was seeing but added massive memory leak or something so we reverted that. Thanks for all bisect work you did!

OCIO filter in ffmpeg.git
by Andrew Randrianasulu 08 Mar '26

08 Mar '26

https://source.ffmpeg.org/gitweb/ffmpeg.git/commit/677cf95ea4be805fa326adb0… looks like it uses standard one input-one output, so it may even work in cinelerra-gg, if nothing else broke.. Not sure how to properly define configuration for such filter - may be Blender have some GUI for this? Random link I stumbled upon while looking at OCIO search results - some notes on digital photography, it seems? https://juraj-notes.tomori.sk/

Forum Out of Sync

Hi, I don't know if it only occurs to me but the pages of the Forum are out of sync. I wrote a post in reply to "Extend a video clip on the timeline" by Chapolin user; if I look at the post without login, today I can see "2 Answers" and my post is hidden. But if I change the option from "Most Voted" to "Oldest", or "Newer", my post is showed and the "Answers" are 3. Same thing for the column of "Recent Posts" on the right of the screen. Links to: https://cinelerra-gg.org/forum/help-video/extend-a-video-clip-on-the-timeli… https://cinelerra-gg.org/forum/help-video/extend-a-video-clip-on-the-timeli… IgorBeg

Settings|Preferences|Performance|Use HW Device: QSV missing
by Terje J. Hanssen 04 Mar '26

I wonder if "Settings|Preferences|Performance|Use HW Device" is meant to set both gpu accelerated decoding and encoding (rendering)? and how does this possibly interact/work with selecting video preset, compression hwaccel methods or not? Use HW Device has available 5 options: none, vaapi, vdpau, cuda, vulkan, while qsv is missing, reason? I ran two av1_qsv rendering tests on Intel AlderLake/DG2 Using HW Device: None and vaapi respectively to exemplify this using the latest Cinelerra Infinity - built: Mar 1 2026 06:30:41 1) Settings|Preferences|Performance|Use HW Device: None file: hdv09_04.m2t compression av1_qsv_8b420.mp4 # Requires specific GPU hardware encoding capability # as well as required software implementation. cin_pix_fmt=nv12 profile=main # global_quality=25 libva info: VA-API version 1.23.0 libva info: Trying to open /usr/lib64/dri/iHD_drv_video.so libva info: Found init function __vaDriverInit_1_22 libva info: va_openDriver() returns 0 libva info: VA-API version 1.23.0 libva info: Trying to open /usr/lib64/dri/iHD_drv_video.so libva info: Found init function __vaDriverInit_1_22 libva info: va_openDriver() returns 0 Render::render_single: Session finished. ** rendered 5972 frames in 18.274 secs, 326.803 fps audio0 pad 64 0 (64) Fast and adequate quality/colors, although global quality may increase it somewhat. 2) Settings|Preferences|Performance|Use HW Device: vaapi (just to test) file: hdv09_04.m2t compression av1_qsv_8b420.mp4 # Requires specific GPU hardware encoding capability # as well as required software implementation. cin_pix_fmt=nv12 profile=main # global_quality=25 libva info: VA-API version 1.23.0 libva info: Trying to open /usr/lib64/dri/iHD_drv_video.so libva info: Found init function __vaDriverInit_1_22 libva info: va_openDriver() returns 0 libva info: VA-API version 1.23.0 libva info: Trying to open /usr/lib64/dri/iHD_drv_video.so libva info: Found init function __vaDriverInit_1_22 libva info: va_openDriver() returns 0 int FFVideoConvert::convert_picture_vframe(VFrame*, AVFrame*, AVFrame*): Error retrieving data from GPU to CPU file: /Videoklipp/AV1/hdv09_04.m2t int FFVideoConvert::convert_picture_vframe(VFrame*, AVFrame*, AVFrame*): Error retrieving data from GPU to CPU file: /Videoklipp/AV1/hdv09_04.m2t int FFVideoConvert::convert_picture_vframe(VFrame*, AVFrame*, AVFrame*): Error retrieving data from GPU to CPU file: /Videoklipp/AV1/hdv09_04.m2t Render::render_single: Session finished. ** rendered 5972 frames in 33.049 secs, 180.701 fps audio0 pad 64 0 (64) Decoder libdav1d does not support device type vaapi.

thirdparty ffmpeg-8.0 vs system ffmpeg-8.0.1
by Terje J. Hanssen 03 Mar '26

03 Mar '26

I build a standard single-user, static bundled Cingg and looked at the thirdparty ffmpeg-8.0 cd /cinelerra/cinelerra-5.1/thirdparty/ffmpeg-8.0 Trying to verify its available hwaccels methods: ./ffmpeg -hwaccels Hardware acceleration methods: vdpau cuda vaapi Verifying the same with my system ffmpeg-8.0.1 on Tumbleweed-Slowroll I get ffmpeg -hide_banner -hwaccels Hardware acceleration methods: vdpau cuda vaapi qsv drm vulkan I wonder why not also the thirdparty ffmpeg-8.0 does list "qsv" and "vulkan"? Seemingly among encoders "--enable-libvpl" and "--enable-vulkan" are listed.

My device not longer support vulkan capabillty
by Terje J. Hanssen 02 Mar '26

02 Mar '26

I had to re-install openSUSE Tw-Slowroll on my Dell XPS-13/9370 with i7/ UHD620 iGPU ( Intel Coffe Lake, gen8, 2017). It worked previously when I tested cin-12-02-2026-x86_64.AppImage and ffmpeg transcoding with h264_vulkan before that. The equivalent tests errors out with h264_vulkan, but works with h264_vaapi and h264_qsv Cingg ------ [h264_vulkan @ 0x7f2f462a0900] Device does not support the VK_KHR_video_maintenance1 extension! FFMPEG::open_encoder err: Function not implemented int FFMPEG::open_encoder(const char*, const char*): open failed h264_vulkan:/home/terje/Videos/hdv09_04_cin_h264_vulkan_8b420.mp4 Render::render_single: Session finished. ffmpeg-8 (system) ----------------- [h264_vulkan @ 0x55c10724c340] Device does not support the VK_KHR_video_maintenance1 extension!

I have verified that the same tests work on my 2 year more legacy Sky Lake with i7/ HD530 iGPU (gen6, 2015) and Slowroll. -------- So far I have not discovered possible missing package, driver or lib that cause this issue, so troubleshooting hints are welcome.

Another test appimage, hopefully this time with onevpl/vulkan/libplacebo/zimg
by Andrew Randrianasulu 01 Mar '26

01 Mar '26

https://disk.yandex.ru/d/Eqvrpylgwvc7Rw I fighted libplacebo and not sure who won - there is no Vulkan device in qemu VM! Try when you can and tell me what works? I did not include 16bpc crash fixes there, but without specifical env. variable those old new formats should not show up
