The last mlt bump was reverted because of #411302, would you please check if the problem persists? If so, we probably can't backport this PR.

How to reproduce the original issue #411302?
nix-build -I nixpkgs=flake:nixpkgs/e4633ab26454 --expr 'with import <nixpkgs> { }; pkgs.mlt.override {cudaSupport = true;}'
just succeeds.

Does nix-build -I nixpkgs=flake:nixpkgs/e4633ab26454 --expr 'with import <nixpkgs> { config.cudaSupport = true; }; pkgs.mlt' work for you?

I see, it fails.

But it succeeds with nixpkgs=flake:github:woffs/nixpkgs/shotcut-25.05 (this PR) and even with nixpkgs=flake:github:woffs/nixpkgs/shotcut-25.05-bpo (this PR, backported to release-25.05). 🙂

Working hard or hardly working?

Heads up: 25.08.16¹ was just released

I am using Shotcut 25.01.25 on Unstable.

I was unable to create any simple text filters, and rich text filters are absent from the filter list. I infer this may be related to #420054 which I also experienced.

#420054 can be worked around by using ffmpeg to convert the image to a looped video. Example:

ffmpeg -loop 1 -i dt_far_resized.png -c:v libx264 -t 5 -pix_fmt yuv420p -vf "format=yuv420p" dt_far_resized_video.mp4

I ran:

nix run github:woffs/nixpkgs/shotcut-25.05#shotcut

This version allowed me to create text filters and the absent filters were present.

I also tested the ability to drag .png files onto the timeline. That is fixed as well.

Great work thank you @woffs

Can this PR be merged? It can fix build with cmake 4 for shotcut and simplify my life ;)

@wegank thank you for merging. I do not understand why the movit commit has been inserted here though.
