Linux mentioned, but not possible to get working?

[spacelama]

There's several mentions on Linux/ubuntu etc in eg README.md, but judging from requirements.txt, this is never going to work with the dependency on pywin32 and inherent dependencies on things such as mpv-2.dll. Looking at git log/git blame, it looks like linux has been an afterthought since well before 4420ee3 and maybe all the way back to v2.1.4 (which I couldn't get pip3 install -r requirements.txt to run anyway).

If it's no longer a consideration, maybe that should be clarified in README.md.

[dfaker]

The win32 module is only used for supporting long and network hosted files on Windows, and the import is skipped on other platforms.

And yes on Linux it's the .so version of the library not the .dll, support for either us handled by pythonmpv.

Looks like removing the win32 line from the requirements.txt should get it all installing for you. I'll see about adding in a Linux specific requirements.txt

[spacelama]

OK, I had further problems when I tried that originally, but didn't realise most of the python stack dumps were from code paths that were try/excepted. Still unable to test probably because of my libmpv version (libmpv1) - I can't test that until I'm in a position to update my workstation from debian oldstable.
(install instructions for linux could probably do with a note to ensure apt install libmpv2 or equivalent if available)

[hanami117]

Is it still not possible to run this on Linux? I recently put Manjaro and I'd love to have this on it. I really like the tool.

[dfaker]

@LeKite I've added a requirements-linux.txt now skipping the win32 dependency, that along with libmpv2 should be all you need, give it a go and if you get any failures we'll see what additional guidance we need to add to a linux install note.

[hanami117]

Mmm im very stupid to know how to make it run though. An AUR package would be awesome

[broconut123]

Haven't used this program in a while but I cloned it today and i'm unable to get it to work. Using arch linux.

@broconut123 That background property was renamed in the last mpv release, patched now in #111

[broconut123]

@dfaker thanks!

[hanami117]

@broconut123 hey buddy I saw you're using Arch.. would you help me make this run? ;w;

[broconut123]

@broconut123 hey buddy I saw you're using Arch.. would you help me make this run? ;w;

Sure. Install tk and possibly mpv with aur helper yay or paru

paru -S tk mpv

cd into the webmgenerator folder

make a virtual environment https://wiki.archlinux.org/title/Python/Virtual_environment
python -m venv envname
then activate environment with
source envname/bin/activate
then
pip install -r requirements-linux.txt
then run it with
python webmGenerator.py

python webmGenerator.py

I will try this asap. Is mpv from AUR needed? I think I run it from arch repo

Holy it worked! Thanks! This should be added as a Linux installation guide by @dfaker Imo! Thanks a lot I really missed this on Arch :)

I have to add, I made webms previously with this method on Arch...

[dfaker]

@LeKite not really enough to go on there apart from ffmpeg is failing to produce a file.

"previously with this method" could mean anything!

Is this for all encode types? (mp4 and VP8 webm too for example), do you have any filters applied?

What ffmpeg version do you have installed?
