Option to add ffmpeg arguments to settings

The FfmpegRecorderSettings class could benefit from having a field where users can declare their own arguments they want to pass to ffmpeg.

In my use case I'm getting flipped video in the linux editor

Alpha channel

Hey!

Can FFmpegRecorder export the alpha when using the HAP Alpha codec?
My camera clear flags is Solid Color with black and alpha 0.
Since for image sequence, PNG alpha is only enabled for Targeted Camera, I tried that too, no Alpha option appears.

Thanks,
Roger

Editor freezes after recording a few ten seconds when frame rate conversion is enabled

vertical flip issue still happens

There is also no option to flip it if you use game view.

Unity Recorder 2.2.0

With Unity Recorder 2.2.0 the OutputWidth and OutputHeight are exposed, so there's no need to use GetOutputWidth() in FFMpegRecorderUtil.cs.

FfmpegRecorder.cs, line 35 can be changed from
+ " -video_size " + input.GetOutputWidth() + "x" + input.GetOutputHeight()
to
+ " -video_size " + input.OutputWidth + "x" + input.OutputHeight

Missing executeable?

Where do you have to install FFmpeg to use this script? I have FFmpeg build installed and PATH variables set up. Thanks
Console Error:
Failed to initialize an FFmpeg session due to missing executable file. Please check FFmpeg installation.
UnityEngine.Debug:LogError(Object)

Output resolution does not overwrite Game View resolution

Reproduction:

Add Ffmpeg recorder in recorder window
Set Output Resolution to for example 1080p
Open Game window
Set resolution in Game window to for example 60:40
Hit start recording
The output video will be 1080p but stretched from 60:40 (blurry)
