Add option for --no-audio and crop options

[bruno-dogancic]

Dear Kenny,

Thank you for such a great peace of software!

My friends and I have been using it for quite some time and one of them recently got into some encoders errors.

( bug reported on Genymobile/scrcpy#3859 )

I've found a simple workaround, use --no-audio flag.

Can you please add option for this (my friend would be extremely thankful!) 😸

I, on the other hand ,would be grateful to have an option to "crop" the stream (as per https://github.com/Genymobile/scrcpy/blob/master/doc/video.md#crop ). I find this quite useful when using the software as whiteboard for giving lectures to students with my Galaxy Tab S8+; but the software I use for drawing (Noteshelf) doesn't support full screen drawing, so I'm always left with lot's of borders around the screen. This way I can nicely lock the paper size and trim everything not needed to declutter the working space (e.g color palette and arriving notifications).

I've already seen someone requesting saving last used settings, but if this would be combined with the option to save presets (e.g, "Lectures" with "scrcpy --no-audio -b 6M --max-fps=15 --crop=1752:2800:140:0 --display-buffer=50 -m 1024") it would be a real killer feature. This was the line of code I had to copy each time starting scrcpy, and would love to see this behind the GUI of SCRCPY+ 🤗

Once more, thank you and have a great day!
Bruno
