How to get audio?

WARN: [FFmpeg] track 1: codec frame size is not set

This warning is "expected" (MediaCodec does not provide the audio frame size), and is harmless.

Records video fine, but never any audio

Do you have audio when you don't record?

What player do you use to play your recorded file? Try with VLC (or even Firefox).

I have tried this on my Oppo phone and Samsung S8 tablet. Different microphones with cable and bluetooth connections.

When I just run scrcpy from Terminal I get the video on screen, but where am I going to see an audio signal/feed to know if I have audio? There is nothing except MacBook Microphone as input options in Sound Preferences. I thought the only place would be in the scrcpy recording, but theres no audio in VLC, quicktime or just quick preview is there any audio. Load a recording into a video editor and there is nothing in the audio track.

MP4 is being saved to MacBook, which seems to be against readme description of it being saved onto android device.

Sorry if I’m just not understanding how to use scrcpy, but am left screen mirroring to macbook and recording audio on that directly.

Audio forwarding means that the Android device audio output (for example if you play a video on your device) is played on your computer on the default audio output.

OK so it seems your audio is not recorded on your device for some reason. Do you have any bluetooth earphones connected on the device (they might disable audio capture on the device)?

In scrcpy, the file is recorded on the computer.

Okay, Samsung S8 doesn’t have 3.5mm jack so have been using bluetooth headset, but I will try using its own microphone and perhaps a USB-C connection? Not sure. I will let you know how that goes. Its true the bluetooth headset does not record audio on numerous android voice recorder apps, but today I was using 4 different cabled mics into oppo and none of them gave me audio.

Oppo phone usb connected to MacBook Run scrcpy Nothing in 3.5mm jack on phone, headphones in MacBook Audio forwarding Playing a video on device, audio is routed to MacBook headphones

Open voice recorder on phone Plug another earphone with mic into phone. Hit record It’s recording voice through earpiece mic, not phone mic But when I playback, its playing back though earpiece headphone, not routing through usb to MacBook

Ultiimately i am trying to record the screen of the tablet while talking about what I am sketching. The app being used is a drawing app, so I’m not sure what will be listening to the phone mic, or cable of routing it because no apps are running to do that.

I have the phone in developer mode, usb audio routing is not disabled. Not sure if any of that is relevant. I will continue to use it as screen monitoring only and record the audio from the MacBook running a screen grab app.

Do not connect any bluetooth earphone, and use:

scrcpy --audio-source=mic --record=file.mp4

(you will get the device screen capture with the audio capture from your phone microphone)

macasas commented 12 months ago

Okay thanks, technically this is now passing the tablet microphone through to the MacBook, but the tablet microphone is not useable to record my voice, its extremely sensitive picking up every little noise and movement, so because the S8 does not have a microphone input connection except bluetooth, or usb (but that’s in use with scrcpy), and scrcpy only seems to work with the built in mic, I guess I’m back to the start. Android does seem to have many issues with bluetooth microphones which makes me wonder why Samsung chose to leave out the 3.5 connector. I do still love the screen mirroring, so easy to use, no lag, better than all the other apps I tried.

I have the same warning but my Galaxy S23 Ultra does record audio and video fine.

Screen res 1080x2312 for reference.
