Two links on ICC in MP4
by Andrew Randrianasulu 14 Apr '25

14 Apr '25

Starter thread, at least back in time (2022) it was not easy/possible to use ffmpeg for adding custom icc profile to mp4 container but MP4Box from gpac project was up to task: https://superuser.com/questions/1739082/embedding-a-custom-icc-profile-in-a… ===== Creating MP4 video without ICC profile (for testing): ffmpeg -y -loop 1 -framerate 1 -i icc_chelsea.png -vcodec libx265 -t 10 chelsea.mp4 Extracting the ICC profile: magick icc_chelsea.png profile.icc Adding the ICC profile to the MP4 video file using MP4Box: MP4Box -add video.mp4#video:colr=prof,profile.icc -new icc_video.mp4 Testing with FFprobe: ffprobe icc_chelsea.mp4 ===== end of quotation ==== As far as I understand in this case idea was to embed display profile into media. But few apps outside of Final Cut Pro/quicktime can do anything useful about this info? https://forum.luminous-landscape.com/index.php?topic=129232.0 this one from ~2019. It states that instead of more flexible color management video world used few fixed mode monitor color spaces, and whole process was a bit manual if your input image/video was not in one of those. I think we hit crudest form of this limitation when we try to fade titler's text over png image. It sort of flashes, due to missing (unapplied) 2.4 gamma step?

Libtheora encoder/cingg <->ffmpeg interop?

13 Apr '25

I was testing our libtheora encoder/muxer after updating to libtheora 1.2.0 and noticed that ffmpeg complains about "(non)keyframe not correctly marked" ~/cinelerra/cinelerra-5.1 $ ffmpeg -i ~/svt_t.ogg -f null /dev/null ffmpeg version 7.1.1 Copyright (c) 2000-2025 the FFmpeg developers built with Android (12470979, +pgo, +bolt, +lto, +mlgo, based on r522817c) clang version 18.0.3 ( https://android.googlesource.com/toolchain/llvm-project d8003a456d14a3deb8054cdaa529ffbf02d9b262) configuration: --arch=aarch64 --as=aarch64-linux-android-clang --cc=aarch64-linux-android-clang --cxx=aarch64-linux-android-clang++ --nm=llvm-nm --ar=llvm-ar --ranlib=llvm-ranlib --pkg-config=/home/builder/.termux-build/_cache/android-r27c-api-24-v1/bin/pkg-config --strip=llvm-strip --cross-prefix=aarch64-linux-android- --disable-indevs --disable-outdevs --enable-indev=lavfi --disable-static --disable-symver --enable-cross-compile --enable-gnutls --enable-gpl --enable-version3 --enable-jni --enable-lcms2 --enable-libaom --enable-libass --enable-libbluray --enable-libdav1d --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libgme --enable-libharfbuzz --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenmpt --enable-libopus --enable-librav1e --enable-librubberband --enable-libsoxr --enable-libsrt --enable-libssh --enable-libsvtav1 --enable-libtheora --enable-libv4l2 --enable-libvidstab --enable-libvmaf --enable-libvo-amrwbenc --enable-libvorbis --enable-libvpx --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxml2 --enable-libxvid --enable-libzimg --enable-libzmq --enable-mediacodec --enable-opencl --enable-shared --prefix=/data/data/com.termux/files/usr --target-os=android --extra-libs=-landroid-glob --disable-vulkan --enable-neon --disable-libfdk-aac libavutil 59. 39.100 / 59. 39.100 libavcodec 61. 19.101 / 61. 19.101 libavformat 61. 7.100 / 61. 7.100 libavdevice 61. 3.100 / 61. 3.100 libavfilter 10. 4.100 / 10. 4.100 libswscale 8. 3.100 / 8. 3.100 libswresample 5. 3.100 / 5. 3.100 libpostproc 58. 3.100 / 58. 3.100 [ogg @ 0xb40000710c40f4d0] Broken file, keyframe not correctly marked.

Some changes for testing purposes for clipping and speed
by Phyllis Smith 13 Apr '25

13 Apr '25

An x86 AppImage for older Operating Systems AND with the alternative shortcut set is at: https://cinelerra-gg.org/download/testing/cin-x86_alternative.AppImage Hoping *IgorBeghetto* might get a chance to test this weekend. Changes included are for - Blur plugin should prevent clipping (Andrea has tested successfully) - Title plugin should prevent clipping (Andrea has tested successfully) - Because BT #672 (https://www.cinelerra-gg.org/bugtracker/view.php?id=672) was fixed without real understanding of the underlying problem, testing of Speed and especially Bump Autos (which is what I think that the original blunder fix addressed) would be helpful. Explanation of Bump Autos is still online at: https://cinelerra-gg.org/download/testing/bump_autos.pdf Feedback welcome. Thanks, Phyllis

Can you re-add old ffnvcodec archive?
by Andrew Randrianasulu 11 Apr '25

11 Apr '25

but under different name like may be ffnvcodec-old.tar.xz ? I tried my Slackware 15.0 x64 + nvidia 470.xx proprietary drivers and h264-nvenc only works with old headers (at around 100 fps for 720p) Downloading and replacing archive is not big deal, but can be surprizing for user less versed in intimate relation between driver version and ffmpeg/ffnvheaders. ref: (kdenlive and GF630) https://www.linux.org.ru/forum/desktop/17219674

static hdr metadata generation ....
by Andrew Randrianasulu 11 Apr '25

11 Apr '25

Found this code on github via some comment discussion https://github.com/HDRWCG/HDRStaticMetadata ah, such a mix of opencv/qtgui! but may be it exposes enough to make it into pure c++ pass? Still no idea how dynamic metadata work .. there are standarts but they a bit hard to read for me: https://pub.smpte.org/pub/st2094-10/st2094-10-2021.pdf https://pub.smpte.org/pub/st2094-40/st2094-40-2020.pdf Tonemapping using those already supported by ffmpeg's libplacebo filter, but this one need Vulkan driver/device! And how to *construct* those types of metadata is not clear for me .....

Update on Blend Algebra / Blend Program plugins
by Phyllis Smith 11 Apr '25

11 Apr '25

*SGE* "no user impact" patch applied in GIT source checkin for increased robustness which you can see if you want at: https://www.cinelerra-gg.org/bugtracker/view.php?id=670 For those who take advantage of *Andrey*'s package releases for automatic updates, they are building and are at: https://github.com/einhander/cin-gg-packages/releases Also, checked into GIT Manual a few minor changes to the wording, punctuation, and removing commentary that I found interesting but would not help the user in usage (for example, "there is proof that any program has infinite number of undetected bugs"!!). Modified the Developer's section to put these plugins' workflow here so that developers can follow this methodology to in the future to add additional effects, because as was stated "one can more quickly test different combinations without spending time to restart Cinelerra, recompile it, reload project, and reattach plugins, etc.". Section is "*Unique Blend plugins workflow*". After I do some more checking, I will at least update the PDF document on the website. *Andrea *had provided some latex fixes for other plugin figures that were out of whack that I checked in too. And if he has time, could he check that I got them right? I spotted another figure that needed fixing but I can not remember where it was. *IgorBeg* - curiosity question -- does the white line on the bottom of the Blend Algebra icon represent the fact that it combines its tracks? or does it represent the fact that there are multiple tracks? or something else?

libsvtav1 2.3.0 patch for cmake 4.0
by Andrew Randrianasulu 09 Apr '25

09 Apr '25

Again, tested only on Arch, but should be safer because we only build libsvtav1 on Linux distros where cmake > 3.16 ? sorry for 2.3.9 typo, must be 2.3.0 (harmaless)

Alternative patch for x265 and cmake 4.0
by Andrew Randrianasulu 09 Apr '25

09 Apr '25

Use it instead of my previous patch? Tested on updated today Arch linux, it will be nice if it will not break ubuntu 16.04 (i tried to set cmake version to 3.5.1)

Paste without the remainder moving
by Stefan de Konink 08 Apr '25

08 Apr '25

Is there an option to copy paste everything (track, keyframes, etc.) so it would overwrite, instead of move the remainder of the track to the right? -- Stefan
