Add --no-video (to mirror audio only)

[rom1v]

As a first step, rename --no-display to --no-mirror:

• the option impacts both video and audio playback, so "no display" is not an appropriate name
• it is confusing with the option --display= which is totally unrelated (it refers to the device display)

Using the short version -N works as before.

Using --no-display still works, but generates a warning:

WARN: --no-display is deprecated, use --no-mirror instead.

Then add a new option --no-video:

scrcpy --no-video

And adapt recording to audio files:

scrcpy --no-video --record=file.opus
scrcpy --no-video --audio-codec=aac --record-file=file.aac
# .m4a/.mp4 and .mka/.mkv are also supported for both opus and aac

To record only:

scrcpy --no-mirror --record=file.opus

The opus muxer has been added to the prebuilt FFmpeg for windows releases: https://github.com/rom1v/scrcpy-deps/commits/6.0-scrcpy-3

Fixes #3842

Just tried the --no-video, it works great.
I have no need to test other features of this PR, but if you want I can.

@Piripe Thank you for your tests 👍

If you could test recording only the audio to .opus and .aac and play it with some player (vlc, firefox, other…) to confirm that everything is ok, that would be great :)

[Piripe]

I tried recording only the audio with and without the mirroring, it works great!



I also made a little AHK script (I edited the script in the autoadb issues) using autoadb and scrcpy, I really like this way to mirror my phone 😀

(Note: I'm REALLY unorganized, as you can see in my taskbar)

The script:

#NoTrayIcon
#Persistent

global hAutoadb

/* Setup Tray icon and add item that will handle
 * double click events
 */
Menu Tray, Icon
Menu Tray, Icon, icon.ico
Menu Tray, Add, Show / Hide autoadb, TrayClick
Menu Tray, Add, Mirror Display, DisplayClick
Menu Tray, Default, Mirror Display

;// Run autoadb hidden
DetectHiddenWindows On
Run autoadb scrcpy --no-video,, Hide, PID
WinWait ahk_pid %PID%
hAutoadb := WinExist()
DetectHiddenWindows Off
return

TrayClick:
OnTrayClick()
return

DisplayClick:
Run scrcpy --no-audio --turn-screen-off --stay-awake --show-touches -b 30M,,, PID
WinWait ahk_pid %PID%
hScrcpy := WinExist()
WinHide ahk_id %hScrcpy%
return

;// Show / hide Autoadb on double click
OnTrayClick() {
	if DllCall("IsWindowVisible", "Ptr", hAutoadb) {
		WinHide ahk_id %hAutoadb%
	
	} else {
		WinShow ahk_id %hAutoadb%
		WinActivate ahk_id %hAutoadb%
	}
}

Hi, will this work with v4l2? Currently, v4l2 with no display with --required-audio doesn't stream audio

I plan to add --no-mirror-video and --no-mirror-audio later (where --no-mirror would be an alias for both), so that you could use:

scrcpy --no-mirror-video --v4l2-sink=…

[rom1v]

Question about the option name: in this MR, --no-display has been renamed to --no-mirror.

I'm wondering if it should be called --no-playback instead (and --no-video-playback/--no-audio-playback for individual streams)?

For example, if we use a V4L2 think without a scrcpy window (scrcpy --no-mirror --v4l2-sink=/dev/video2), then we can consider we are still "mirroring" the device?

What do you think?

[Piripe]

Yeah, it would be more intuitive
