SUMMARY
Sometimes I still like to use Macromedia Flash 8 for nostalgia reasons, but I'm sure this issue applies to anyone using CS3->CS6 as well. If you click to import a video clip or image sequence, and select filter to "All supported files", the swf file will show up. Yet it prints back "cannot open [filepath].swf"

I've tested this on Microsoft Windows build, the GNU/Linux appimage as well as the Flatpak build. All 3 give the same results. I'll attach here a zip file containing the swf example which is just a simple motion tween and the log if there is anything of value in it.


STEPS TO REPRODUCE
1. Click "Add clip or folder" button
2. Go to the directory where the swf file is located.
3.  Double click it.
4. See resulting message.

OBSERVED RESULT


EXPECTED RESULT
The .swf file was imported and I can use the video contents in kdnelive

swf support comes from FFmpeg. Unfortunately, only some swf files are supported. For example this one works:
https://filesamples.com/samples/video/swf/sample_640x360.swf

I think some swf files contain audio/video streams readable by FFmpeg, some do not. Nothing we can do here, sorry.
