Hi,

I'd like to display the current audio1 input level on the left side of video1, and audio2 input level on video2.
I'd like to query the db from amixer like this:

awk -F "[][]" '/dB/ {print $2}' <(amixer sget DEVICE)

But there are a lot of output as device if I type in amixer in the encoder.

Could you help me out of which device name corresponds to in1 and in2?

And if I got the db number I'd make a script that created a symlink in every second pointing 0-100 prearranged gifs, and that symlink would be set as overlay image.
This way when I record, I hope I could have a nice green dot moving constanty accordingly the current input level

Could I modify the firmware by inserting into the gstreamer pipeline to get something like his on the side of the video?

Please help me out a bit with this.

Thanks

Zolee
