So, because I learned about sbopkg tool, installing packages from Slackbuilds.org semi-automatically I had field day compiling stuff: /tmp/Catch-2.13.10-i586-1_SBo.tgz /tmp/audacity-3.2.5-i586-1_SBo.tgz /tmp/avidemux-2.8.1-i586-1_SBo.tgz /tmp/cppy-1.2.0-i586-1_SBo.tgz /tmp/cppzmq-4.10.0-i586-1_SBo.tgz /tmp/flowblade-24564a-i586-1_SBo.tgz /tmp/gst-editing-services-1.18.5-i586-1_SBo.tgz /tmp/gst-python-1.18.5-i586-1_SBo.tgz /tmp/kiwi-1.9.29-i586-1_SBo.tgz /tmp/libopenshot-0.3.2-i586-1_SBo.tgz /tmp/libopenshot-audio-0.3.2-i586-1_SBo.tgz /tmp/libsbsms-20220812_e6c9c3b-i586-1_SBo.tgz /tmp/mlt-bindings-7.4.0-i586-1_SBo.tgz /tmp/openmpi-4.1.4-i586-1_SBo.tgz /tmp/openshot-3.1.1-i586-1_SBo.tgz /tmp/pitivi-2023.03-i586-1_SBo.tgz /tmp/portaudio-19.7.0-i586-1_SBo.tgz /tmp/portmidi-2.0.2-i586-3_SBo.tgz /tmp/portsmf-234-i586-1_SBo.tgz /tmp/protobuf3-3.20.1-i586-1_SBo.tgz /tmp/python3-cycler-0.11.0-i586-1_SBo.tgz /tmp/python3-kiwisolver-1.4.1-i586-1_SBo.tgz /tmp/python3-matplotlib-3.4.3-i586-2_SBo.tgz /tmp/python3-pyzmq-25.1.0-i586-1_SBo.tgz /tmp/shotcut-21.12.24-i586-1_SBo.tgz /tmp/soxr-0.1.3-i586-1_SBo.tgz /tmp/unittest-cpp-2.0.0-i586-1_SBo.tgz /tmp/zeromq-4.3.4-i586-1_SBo.tgz You see, bunch of editors and their dependencies. Avidemux 2.8.1: compiles with va-api, then promptly crashes :) LIBVA_DRIVER_NAME=none avidemux3_qt5 this way it works, at least video playback part. I also learned Cmake 3.21 at least can't find X11 libs in their /usr/X11R7/lib hidden place, even with pkg-config. So, few symlinks did the job. Flowblade (some git version) : Wanted MLT 7.0.4 obviously and then worked on video playback Just ..main window much longer than 1440 px I have! shotcut - 21.12.24: A bit old, but shows up for work. Need sip/pyQt5. openshot-3.1.1: Promised better stability and performance. Plays clip at least .. www.openshot.org/ru/blog/2023/04/20/new_openshot_release_311/ pitivi : Pity it does not work on 32-bit :) bash-5.1$ pitivi Отсутствующая необязательная зависимость: — GSound не найден в системе -> включает звуковые уведомления по завершении сборки Отсутствующая необязательная зависимость: — элемент GStreamer cvtracker не найден в системе -> позволяет отслеживать объекты Отсутствующая необязательная зависимость: — librosa не найден в системе -> включает возможность обнаружения тактов OverflowError: Python int too large to convert to C long The above exception was the direct cause of the following exception: Traceback (most recent call last): File "/usr/lib/pitivi/python/pitivi/utils/pipeline.py", line 633, in _bus_message_cb if message.type == Gst.MessageType.ASYNC_DONE and\ SystemError: <built-in method get_value of gi.FieldInfo object at 0xf45a1e60> returned a result with an error set OverflowError: Python int too large to convert to C long The above exception was the direct cause of the following exception: === https://sebhastian.com/python-int-too-large-to-convert-to-c-long/ apparently 32-bit problem. New Audacity 3.2.5 crashed once, not sure why (their playhead manipulation a bit different by default) KiCAD 7.0.6 (modded Slackbuild) failed to load wxPython - no python scripting ... { Not really video editor, but can make 3d models of PCB (printed circuits board). 3d models for it weight like 5 Gb unpacked :) } Freecad 0.20 apparently can make short animations - installed but not tried. https://wiki.freecad.org/Release_notes_0.20 This is why I am not big fan of Python - it breaks in non-obvious ways ... So, I think CinGG still best idea around* when it comes to video :) *on my machine :) Thanks everyone! I'll try to watch new video 'soon', as fast as I report (re-report) this wxPython / kiCAD bug ..
