Is it possible to access Audio buffers to retrieve info for a VUMeter? about streampack HOT 8 OPEN

Hello :)

I was kind of expecting this request.
There is a branch where you can get peak and/or rms value of each audio channels: https://github.com/ThibaultBee/StreamPack/tree/feature/vu-meter. I just rebased it. Is it what you are looking for? Are you going to use rms and/or peak value?

The only things missing for now is that when preview is running, you won't get any value cause audio capture is not running and I still don't really know how to implement this part.

Hello :)

this is great! exactly what I wanted! thanks :)

I don't need the values while previewing but from what I can understand you can just startRecording on the AudioRecord and discard the Frames after getting the measurements.

Hi,
This is the issue: there aren't any audio frames when encoder is not running. It means that you can only access audio frame when StreamPack is live streaming.

Yes, I know. To get audio frames you need to start recording when preview starts and discard audio frames instead of streaming them. But in my case this isn't an issue at all.

Another question on a different matter: Is it possible to get any metrics from streaming? just wondering :)

What metrics do you have in mind?

from streampack.

latency, bandwidth, frame rate, bitrate. I am not sure if those are possible at all.

Do you use SRT or RTMP?
I guess it is quite easy to return latency, bandwidth and network bitrate with SRT, not sure about RTMP.
