Can't open video files

I’m new to Shotcut. I’d like to create a video (for Youtube) from videos that I made with my camera. However, when I click “Open File” and select a .MOV, it just says it “failed to open”, without giving any reason. It this normal? What am I doing wrong?

It can’t be all about camera specifics or filename extension, as I get the same error from a random MP4 from the Web, as well as with .AVI files.

Due to an obscure forum restriction, the second screenshot must be in a separate post…

This is just a guess, but do you have any special characters in the file name/path? I.e. letters with accents, umlauts, or anything else (like á, ü, or ß)? If so, try removing those characters and see if you still run into the same issue.

No. You can see the path and filename in the screenshots. Even with the underscore removed, it does not work.

Is there a sensible error message in the logfile ViewLogfile?

Your problem appears to be one of a bad package or build or missing dependencies. How did you get and install Shotcut for Linux?

@shotcut: No Linux here. I installed Shortcut via FreeBSD ports.

@Elusien: My menu entry is named “Application Log…” instead of “Logfile”, and it doesn’t reveal much on file-open:

[Debug  ] <MainWindow::open> "/f/video/MVI_3937.MOV" 
[Info   ] <MainWindow::showStatusMessage> "Failed to open /f/video/MVI_3937.MOV" 

But there is a warning at startup:

[Warning] <MLT> mlt_repository_init: failed to dlopen /usr/local/lib/mlt-7/  (/usr/local/lib/ Undefined symbol "usenglish_init")

This error made it to the FreeBSD bugtracker a couple of times, and they obviously still haven’t managed to fully resolve it.

Reinstalling flite didn’t help, but removing flite support from ffmpeg (and removing flite altogether) did the job. I can now open video files in Shotcut and in Kdenlive (where I had the same problem, because it also uses MLT). Thanks.

I assumed I had to compile more things in when a particular file type can’t be opened, but the opposite was true.
