USB microphone

[samsungcoho]

Hi,

I hope you are all well!

Just installed ZM today and so far I love it. I have connected my RPI camera via motioneye. Motioneye doesn't support audio recording so I want to add a USB microphone to ZM so that I have the video with audio. Is this possible? I can do this in ispy but I see no options in any menus in ZM.

If you know if this is possible please let me know!

Thanks!

James

You're going to have to figure out how to mux the video and mic on the Pi and then stream it to ZM.

If it is not too lat; may I ask what your settings are in ZM and MotionEye to get the video stream to be shown in ZM?

In 1.35 will come the ability to mux a separate audio stream.

is microphone recording usable now in the dev version? does it work for locally attached camera via usb with integrated microphone?

[iconnor]

no

Hi
I have similar issue, in my case, i use an uvc webcam with mic integrated, so in ZM (1.32 from my distro (mageia 7.1)), i set as local and /dev/video0, so i don't have sound, my workarroud is like this :
ffmpeg -thread_queue_size 512 -f v4l2 -i /dev/video0 -f pulse -i alsa_input.usb-Sonix_Technology_Co.__Ltd_USB_2.0_Camera_SN0001-02.analog-mono -ac 1 -ar 44100 -an -pass 1 -profile:v high -pix_fmt yuvj420p -level:v 4.1 -preset ultrafast -tune zerolatency -vcodec libx264 -vpre medium -b:a 180000 -bt 180000 -r 10 -b:v 2048k -s 1920x1080 -acodec aac -strict -2 -ac 1 -ar 44100 -ab 256k -listen 1 -f mpegts -flush_packets 0 http://127.0.0.1:8081
and in ZM ffmpeg source and audio passthrough.
with VLC stream is ok, in ZM live view too, but in ZM log i see ZM can't save mp4 event file because of incorect input!
I don't know the litlle arguments whose need to be adjusted!
which debug output i need to provide ?

hum, intersting, changing ffmpeg by cvlc : cvlc v4l2:///dev/video0 :size=1920x1080 :v4l2-standard=525_60 :input-slave=alsa://hw:0,0 :live-caching=300 --sout '#transcode {vcodec=theo,acodec=vorb,samplerate=48000}:std{access=http,mux=ffmpeg{mux=ogg},dst=0.0.0:8083}'

give me an different issue, first in ZM log i got :
