SUMMARY STEPS TO REPRODUCE 1. select a set of images 2. generate video slide show OBSERVED RESULT DebugView output [28140] digikam.general: Failed to open muxer EXPECTED RESULT SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
I just create a few short video slideshows on Windows and can't reproduce any problem. We do not check in depth whether the selected video settings are possible or useful. Which settings did you use exactly? Maik
I ran the same test on LINUX and it works fine, so windows specific. The UI interaction behaves better on LINUX also. Tx
Apiszcz, As Maik said, i also tested under Windows, and i cannot reproduce the problem. Please explain better the dysfunction... BEst Gilles Caulier

Git commit 2eb84eeb93994d93c4b3f4bdb001cba2fba67fb1 by Gilles Caulier. Committed on 04/01/2024 at 11:26. Pushed by cgilles into branch 'master'. Complete isolation of QtAv code. Tested with Qt5 and Qt5. Tested with and without mediaplayer cmake option. The linking problem with QtAv was the auto reccursive parsing of header file in whole source repository. QtAv was always parsed and add to the compilation rules. Not qtav and qtmm are removed from the parse and add at the demand when necessary. Continue to port VideoSlideshw to FFmpeg CLI tool to drop QtAV (Qt5 and Qt6).

Git commit dd325854d3021dacb139d387bd37544bf89d3df8 by Gilles Caulier. Committed on 05/01/2024 at 14:45. Pushed by cgilles into branch 'master'. First version for testing of the new video slideshow tool based on FFmpeg CLI tool to encode images as video. A small demo is available here: https://drive.google.com/file/d/1posBo2rqkatU7N6qkbZWGBbOELsUGdgg/view?usp=sharing It still plenty of features to restore, as to adjust the codecs, the size, the frame rate, the format. The audio track must be supported too. Currently the temporary directory containing frames to encode is not yet deleted at end, it's for debuging. It's planed to remove temp dir when all features will be completed.
