Are you familiar with this project? If I understand it correctly, it is an XOrg layer that works on top of Wayland. It is still in alpha, but it would be interesting to try it with CinGG. I don't really understand the difference with XWayland: "..to host a rootful Xwayland server". https://github.com/wayback-x11/wayback

The waveforms are gone again
by Stefan de Konink 10 Jul '25

10 Jul '25

The embedded waveform seems to be created to only a the first few seconds of the file after which it is blank. For a wav file it does appear. I removed the cached files from .bcast5. Any clue what else I can try? I have attached a screenshot. -- Stefan

64-bit new AppImages but not 32-bit
by Phyllis Smith 06 Jul '25

06 Jul '25

New appimages are now available on the website for the 3 64 bit versions. Although there is not much by way of new work, it was important to make new appimages to revert the FLOAT problem in Titler/Blur mod accidentally introduced last month. Release notes for this is below the next paragraph. The 2 32-bit appimages have a problem in linuxdeploy that I have not analyzed yet. However, neither of the 2 Debian systems, 9.1 and Bullseye, have had zero change made since last setup and are not on the net so could not have been impacted. In addition, I am still using the same linuxdeploy that I have been using since 2021 so I am assuming the binary got too big (although an initial reduction by excluding some libraries did not help). The end of the appimage creation log file is below the release notes. ******** New part of Release Notes GIT for Cinelerra-GG has the following changes from 05/01/2025-06/30/2025 Slackware build needed quotes in the Makefile for the new Blend plugins as noted by Andrew-R. Andrew’s patch was added for libsndfile for gcc15 of the latest Arch as discovered by Andrea. New render formats added include: AVC_Intra_100.mov Andrew created/tested mpeg2hd422p.m2ts – for higher quality at video bitrate > 30Mbp Terje mpeg2sd422p.mkv, mpeg2sd422p.m2ts Terje Vulkan hardware acceleration choice along with tooltip was added by Andrew. Andrew discovered that brender_tmp_delete.sh was not added to Shell Menu items / now fixed. Updated ffmpeg.git.patches for future ffmpeg update to version 8.0. Summarized most useful fixes/features for 2023 and 2024 in the msg/txt file just to keep it manageable. Removed FFmpeg waveform / boxblur filters from Resources Window because crashing/hanging. Unfortunately reversed last release changes to Blur and Titler plugins to be used in combination with other plugins without introducing the clipping into the process as discovered by DeJay when using Float format. **** Error when running linuxdepoy to create appimages on Debian 32-bit ... -- Running output plugin: appimage -- [appimage/stdout] Found appimagetool: /tmp/.mount_linuxdqi2IKy/plugins/linuxdeploy-plugin-appimage/usr/bin/appimagetool [appimage/stdout] [appimage/stderr] Running command: /tmp/.mount_linuxdqi2IKy/plugins/linuxdeploy-plugin-appimage/usr/bin/appimagetool "AppDir" "-g" [appimage/stderr] [appimage/stderr] appimagetool, continuous build (commit 8bbf694), build <local dev build> built on 2020-12-31 11:48:32 UTC [appimage/stderr] fatal: Not a git repository (or any of the parent directories): .git [appimage/stderr] Failed to run 'git rev-parse --short HEAD: Child process exited with code 128 (code 128) [appimage/stdout] /tmp/AppDir/cin.desktop: warning: key "Encoding" in group "Desktop Entry" is deprecated [appimage/stderr] More than one architectures were found of the AppDir source directory "AppDir" [appimage/stderr] A valid architecture with the ARCH environmental variable should be provided [appimage/stderr] e.g. ARCH=x86_64 appimagetool ...
