Can't run PyScenedetect, error related to FFMPEG.

[gphg]

After get it installed then run it.

This is the error:

$ scenedetect -h

CANNOT LINK EXECUTABLE "ffmpeg": cannot locate symbol "eglDestroySyncKHR" referenced by "/system/lib64/libgui.so"...

RuntimeError: No ffmpeg exe could be found. Install ffmpeg on your system, or set the IMAGEIO_FFMPEG_EXE environment variable.

It works normally on Ubuntu termux-proot, but slow and it consumes extra spaces for its dependencies.

I'll post my Termux info if asked.

Edit: ffmpeg is installed.

Edit 2:
Got the environment variable set to ffmpeg binary. It runs, but error during process. I got this on help option:

$ scenedetect -h

Edit 3: it detects, but cannot split video. Not video files has been written

I'll test and report the mkvmerge on Ubuntu termux-proot later.

The issue has been fixed on termux/termux-packages#23067 (tied to that reported issue).

I have to update (or install if not installed) the libandroid-stub package and it is working normally as expected. 👍
