If we go down to python 3.12/3.9, check for just python3 too might fix build on SuSE's Slowroll distro.

ANV driver Vulkan video encoding
by Andrew Randrianasulu 16 Feb '26

16 Feb '26

Interestingly, I followed to actual merge request from 2024 and https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/27810 Cr channel not encoded As problem in h264 encode case. So, may be this bug was not fixed, or re-surfaced at some point in time? I also do not know how to set those encode modes, via avcodec params ?

Vulkan, again
by Andrea paz 16 Feb '26

16 Feb '26

By enabling libplacebo and using the 0012-Experimental-vulkan-encode.patch patch, I was able to render with a Vulkan preset for the first time. However, decoding with Vulkan still does not work for me.. The fact that ffv1_vulkan (with nv12) works but my other presets for hevc, av1, and h264 do not, does that mean I need to find the right pix_fmt for them? Furthermore, nv12 is not suitable for ffv1, which is generally an archiving codec and requires little or no color compression. ( https://trac.ffmpeg.org/ticket/11515) I tried changing the pixel format (from the render configuration window) of your preset from nv12 to: nv16; nv24, p010,p210,y210 and y416. But the result is the same as nv12. ffprobe indicates yuv420p for the various renders. Note: In ./configure, the “--enable-libplacebo” option does not work for me, but the “--with-libplacebo” option does. Note2: I tried the latest appimage made for Terje, even though I don't have Intel hardware, and rendering with Vulkan doesn't work for me.

Can you check if one or both patches fix crash in x11/direct case for yuva16 colormodels ? If yes, I may have color3way fix for those, too

Procedure and build scripts for Unbundled Builds (Slowroll)
by Terje J. Hanssen 12 Feb '26

12 Feb '26

My purpose is to get some procedure review, clarifications and comments, and possibly also submit a few updates to build scripts for unbundled builds with system ffmpeg. My system is current openSUSE Tumbleweed-Slowroll with FFMpeg-8 installed from Packman community reposistory. My understanding is that this should be a single-user build, dynamic linked and that the following two scripts are actual: * bld_prepare.sh (to install all dependices?) * bld_dynamic.sh (does this complete the build procedure?) Cingg Manual reference: 1.3 How to Build CINELERRA-GG from Developer's Git Repository https://download.cinelerra-gg.org/files/CinelerraGG_Manual/How_Build_CINELE… 1) Installation df -h /home3 /dev/nvme0n1p5 49G 9.7G 37G 21% /home3 cd /home3 # zypper in git # zypper in git # git clone https://git.cinelerra-gg.org/goodguy/cinelerra.git Cloning into 'cinelerra'... remote: Enumerating objects: 23232, done. remote: Counting objects: 100% (23232/23232), done. remote: Compressing objects: 100% (14860/14860), done. remote: Total 23232 (delta 11986), reused 17387 (delta 7999), pack-reused 0 Receiving objects: 100% (23232/23232), 452.29 MiB | 26.58 MiB/s, done.

bld_prepare.sh script and Suse Slowroll
by Andrew Randrianasulu 12 Feb '26

12 Feb '26

Terje, if you replace single [ with two [[ in this suse section of script like this - if [ ! -f /usr/lib64/libtermcap.so && ! -L /usr/lib64/libtermcap.so ]; then + if [[ ! -f /usr/lib64/libtermcap.so && ! -L /usr/lib64/libtermcap.so ]]; then will it run zupper line as it should ? I only tested this on Slackware 15.0 with bash 5.3
