I'm unable to reproduce this on Ubuntu 18.04 (kernel 4.15.0-143) using the same v4l2loopback version with/without running `ffplay /dev/video0`. Do you see the issue even without having an app connected...

Also, if you choose a specific device you will see a better error message, for example: ```py with pyvirtualcam.Camera(width=1280, height=720, fps=20, device="/dev/video0") as cam: ``` This must match the device...

Not exactly sure what's going on. How do you create the device? Are you using `exclusive_caps=1` by any chance? Even if, it should still work...

On my end I still can't reproduce it with the same modprobe line you've given, with `exclusive_caps=1`. For me, before running the pyvirtualcam script, `v4l2-ctl` shows "Video Output". While running...

Thanks for looking at it. No I didn't want to use parallel IO but it seems that netcdf-fortran has a hard dependency on those functions, see https://github.com/Unidata/netcdf-fortran/blob/78a9839366cf8cdc929da450ebba9fad941c3341/fortran/nf_nc4.f90#L61. This file is...

I use the mingw64 shell from the MSYS2 package. Note that the person from the [linked issue](https://github.com/Unidata/netcdf-fortran/issues/48#issuecomment-277710507) used the Intel Fortran compiler on Windows and had the same problem. Make...

OK great, I didn't know that about the PGI compiler. On their [feature comparison page](https://www.pgroup.com/products/feature-compare.htm) it says that the free version doesn't have Visual Studio integration. Feel free to contact...

Here are my steps: - Download/Install 64bit MSYS2 from http://repo.msys2.org/distrib/x86_64/msys2-x86_64-20161025.exe - Inside the MSYS shell: - `pacman -Syu` (system upgrade) - Forcefully close and reopen MSYS shell - `pacman -Syu`...

Some more details on why this happens on Windows and not on Linux: - Windows only exports functions in a shared library if they have the correct export markers defined...

@edhartnett I just tried it but get the same errors still. I saw you modified include/netcdf_par.h but this file is not included from `dparallel.c` which is where the implementation resides,...
