Add keyframes and additional video encoder codec settings

[Uzver123]

Please add additional video encoder settings especially the keyframe interval, right now ScrCpy records all-intra videos without any keyframe which is very wasteful in terms of bitrate because bitrate is split across every frame (not compressed at all, each frame same size).

I understand this is probably done to keep resources usage lower on the phone, but not always a desired method. really need ability to specify keyframe interval.

Also need ability to control ISO/exposure etc.

Would be nice if you could add command line to the video encoder so we can pass custom command line options to codec without need to request each individual one as feature.

Hmm, no, it is set to 10 seconds:

scrcpy/server/src/main/java/com/genymobile/scrcpy/SurfaceEncoder.java

Line 17 in 206809a

private static final int DEFAULT_I_FRAME_INTERVAL = 10; // seconds

Would be nice if you could add command line to the video encoder so we can pass custom command line options to codec without need to request each individual one as feature.

This option already exists: --video-codec-options:

    --video-codec-options=key[:type]=value[,...]
        Set a list of comma-separated key:type=value options for the device
        video encoder.
        The possible values for 'type' are 'int' (default), 'long', 'float' and
        'string'.
        The list of possible codec options is available in the Android
        documentation:
        <https://d.android.com/reference/android/media/MediaFormat>

For example:

scrcpy --video-codec-options=i-frame-interval=1

or as a float (since Build.VERSION_CODES.N_MR1):

scrcpy --video-codec-options=i-frame-interval:float=1.5

cf https://developer.android.com/reference/android/media/MediaFormat#KEY_I_FRAME_INTERVAL

Tested, you correct keyframe is there its just every 20 seconds not 10 in my case and i never waited so long on my test.

Oh nice

Is there way to disable auto focus and or set manual focus distance, i know this is probably not done trough the codec.
