av1an: builds but has no console output

[LigH-de]

I built a static Win64 EXE and tried to run it. But there is no console output. I also tested av1an.exe --help but there is no console output either. Does it require additional DLLs in the same directory to start at all? Or how may I proceed to search for a reason?

Also mentioned upstream in Av1an issue #883

[1480c1]

Did you try double clicking from file explorer to see if it gives a dll not found error window?

[LigH-de]

When I double-click it in the Explorer, a console windows opens and closes.

Originally I tested it in a console emulation in the "Far manager".

@Uranite told me in the upstream issue:

you need ffmpeg shared and vapoursynth

So I am not sure whether there are basic issues with a static build. I'll test the shared build as well...

[LigH-de]

Despite selecting av1an=2 it is still built as static EXE, judging by its exactly same size of ~18 MB in both cases.

[Uranite]

I think you just need to install vapoursynth so that you're able to run av1an, I would've said that you need the dlls of ffmpeg shared in your PATH or in the same directory as av1an.exe, but it doesn't seem to be necessary with av1an that is built via media-autobuild_suite, but worth trying nonetheless

I put all the shared FFmpeg DLLs (and more probably unnecessary files) and the Vapoursynth DLLs in the same directory:

Still, no console output. It seems to close already before it is able to print messages about anything missing.

Rust is not automatic installed

update: below is probably just some weird bug, I can't reproduce it now
and FFmpeg.exe is gone after building static linked av1an, and this will not trigger "missing files" next time (if ffmpeg git is not updated)

[L4cache]

master-of-zen/Av1an#885

Currently the newer code of FFmpeg will cause this strange bug, originally tested with av1an latest release (exe upload date 2024-10-03) + FFmpeg 7.1 dlls download from gyan.dev but also apply to the latest git version built by m-ab-s.
(I didn't have this no console output problem...)

Av1an not outputting anything to the console is due to Python and Vapoursynth not being installed. I was under the assumption that they weren't required for runtime, so I hadn't included a disclaimer saying so -- that's my bad

Still, av1an could stand to include an error message like Python not found or Vapoursynth not installed instead of displaying nothing
