Pixiv Ugoria - ffmpeg not working

[subash-ganesan]

I'm trying to download pixiv ugoria and convert them to mkv using ugoria-copy postprocessor. I get below error

As we can see, it is clearly showing gcc is not found. But I can confirm it is installed

gcc --version  1 ✘

It would be helpful if someone could help reolve this

Something is very off here..

You definitely don't need GCC (a compiler) to simply run ffmpeg.

Does ffmpeg work as expected for you? What is your output for ffmpeg -version, for example?

Here's what i got

I can reproduce this error:

ffmpeg: /tmp/_MEIgUt8so/libgcc_s.so.1: version `GCC_13.0.0' not found (required by /usr/lib/libhwy.so.1)

I initially thought this might have been caused by building on an Ubuntu VM (4ccdba8), but even older binaries yield this error:

Probably something related to PyInstaller and its bundled libraries.

You definitely don't need GCC (a compiler) to simply run ffmpeg.

"version 'GCC_13.0.0' not found" relates to the GCC version a .so library was built against and requires to load, I think.

I found the cause and solution to this by accident when looking through yt-dlp code. PyInstaller modifies LD_LIBRARY_PATH such that external programs try to load PyInstaller libraries instead of system libraries first: https://github.com/pyinstaller/pyinstaller/blob/develop/doc/runtime-information.rst#ld_library_path--libpath-considerations
