FFMpeg.JoinImageSequence Input Sample Rate is locked at 25 FPS

[Nashnir]

From my tests the input frame rate at which the images are processed into video is seems to stuck at 25 FPS.

If I have 25 images and I use FFMpeg.JoinImageSequence, I get 1 sec long video irrespective of if I set framerate in the function to 25, 30, 60.
If I have 30 images and I use JoinImageSequence, I get 30/25 seconds indicating it is still processing at 25FPS

Was able to fix this on my end by creating a new JoinImageSequence function.

with the changes

return FFMpegArguments
.FromFileInput(Path.Combine(text2, "%09d" + text), verifyExists: false, delegate (FFMpegArgumentOptions options)
{
options.WithFramerate(30);
})
.OutputToFile(output, overwrite: true, delegate (FFMpegArgumentOptions options)
{
options.ForcePixelFormat("yuv420p").Resize(width.Value, height.Value).WithConstantRateFactor(1).WithFramerate(30);
}).ProcessSynchronously();
