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 ...

HDR and Manual

29 Jun '25

I changed the manual to correct all the (wrong) references I had made to HDR. Can you check if they are now correct or is it better to remove them altogether?

Record HDV cam Live video with IEC61883 failed
by Terje J. Hanssen 27 Jun '25

27 Jun '25

I tried CinGG-20250430-x86_64.AppImage to record HDV cam Live video connected via IEEE-1394 (Sony iLink, Firewire) using the iec61883 driver. According to the manual: The file format must be Quicktime for Linux and video recording must be enabled for it. Click on the wrench to set the video compression. For the IEC 61883 driver, the compression must be DV. https://cinelerra-gg.org/download/CinelerraGG_Manual/Live_Video.html So I tried first Shift-P FFMPEG and qt, mp4 audio and dv_pal.qt video I also tried FFMPEG mpeg, Audio mpeg_mp2, Video mpeg and mpeg_hdv But got these error messages in both cases using default port 0 or alternative port 1 *AVC1394Control::initialize(): couldn't set port: Invalid argument * int FFMPEG::init_encoder(const char*): bad file format: /home/terje/test.mpeg rom1394_0 warning: read failed: 0x0000fffff0000414 AVC1394Control::initialize(): node 0 int FFMPEG::init_encoder(const char*): bad file format: /home/terje/test.mpeg A control test of the connection with the legacy 'dvgrab' recorded a m2t file ok.

Segmented Recording from input stream
by Terje J. Hanssen 23 Jun '25

23 Jun '25

Is it possible with CinGG's Record utility (via FFMPEG) to record a stream to file segments of same duration or file size and use auto-naming? Typical example: Record a video/audio input stream (i.e from playing a camcorder tape cassette) and encode to output file segments of 10 minutes or 10 GB each and auto-name file numbers. Similar example code using an input file instead at https://unix.stackexchange.com/questions/1670/how-can-i-use-ffmpeg-to-split… Just use what is built into ffmpeg to do exactly this. |ffmpeg -i invid.mp4 -threads 3 \ -vcodec copy *-f segment -segment_time 10:00 \ -reset_timestamps 1 \ cam_out_h264_%02d.mp4* | This will split it into roughly 10-minute chunks, split at the relevant keyframes, and will output to the files *|cam_out_h264_01.mp4|, |cam_out_h264_02.mp4|*, etc. Terje J.

mpeg2sd422p presets
by Terje J. Hanssen 20 Jun '25

20 Jun '25

Attached here are two presets for recording SD raw video to mpeg2video with high 30M bitrate and 422p chroma subsampling. Just a quick working test by me so far. A m2ts (mpegts) container is used as for the previous hd variant, to easy be able to combine with pcm_bluray audio. As progressive video, none of these are Blu-ray compliant, but merely for use with media-players. My thought next is therefore to make additional .mkv variants of both presets. Analyzing the Cingg output file with ffprobe: ffprobe -hide_banner mpeg2sd422p.m2ts Input #0, mpegts, from 'mpeg2sd422p.m2ts': Duration: 00:00:20.94, start: 0.020000, bitrate: 33509 kb/s Program 1 Stream #0:0[0x1011]: Video: mpeg2video (4:2:2) ([2][0][0][0] / 0x0002), yuv422p(tv, bt709/unknown/unknown, progressive), 720x576 [SAR 1:1 DAR 5:4], 50 fps, 50 tbr, 90k tbn Side data: cpb: bitrate max/min/avg: 30000000/0/0 buffer size: 25001984 vbv_delay: N/A Stream #0:1[0x1100](eng): Audio: pcm_bluray ([128][0][0][0] / 0x0080), 48000 Hz, stereo, s32 (24 bit), 2304 kb/s The 422p@ML for SD is accepted by the equivalent fmpeg command line, and profile=422p works (not 'main') in the preset. It would be fine to use both profile name and level in the preset if possible (?)

https://www.cinelerra-gg.org/forum/everything-else/titles-fade-not-working/… I will try to reproduce, but I wonder if it could be due to release notes change of: > 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. > If so I will have to back out this mod.

Discovered problem with future ffmpeg 8.0
by Phyllis Smith 13 Jun '25

13 Jun '25

After applying current ffmpeg.git as of May 25: ae0f71a387f05be7ac90d545af4d3aeb8e1cca89 and applying Andrew's patches: 0001-Add-check-for-nb_inputs-before-calling-avfilter_get_.patch 0002-Same-possible-crash-fix-in-ffstreamaudio-for-dynamic.patch 0003-Do-not-filter-out-dynamic_input-filters.patch 0004-HACK-ffmpeg-8.0-build.patch CinGG builds but none of the ffmpeg plugins work. The Video plugins crash (did not try them all, but a few like F_boxblur) when added to the timeline and then click on "Show Controls. The Audio plugins do not crash but you get the warning tone only when you play them (again, I did not try them all, but F_chorus was one of them). I have not looked at the code yet, but most likely it is just an oversight in trying to get it to compile. Also, line 77 in 0004-HACK-ffmpeg-8.0-build.patch has "#esle" instead of "else".

mpeg2hd422p.m2ts - groundwork for a high-end preset

While the newer h.264 and hevc are known for best compression, mpeg2 may have better quality at video bitrate > 30Mbps This example capture a raw video stream (optional tape playback) from the camera sensor over HDMI out and transcode audio to PCM into a high-end mpeg2hd422p.m2ts -input_format yuyv422 -video_size hd1080 possibly may be commented out, as the encoder default uses the maximum capability it get from the capture card ms2130 and driver v4l2 mpeg2video is difficult to get quit perfect with ffmpeg; muxing overhead: 6.206455% is the minimum I have achieved as in this case.
