Thank you for your response.
I am working on an rtsp server that uses V4l2 to get frames from mipi-csi2
and then it will encode with ffmpeg Apis (C/C++ language). As I said with
the ffmpeg command line it is able to encode 1920x1080@29 fps, so now I
need the similar process with C/C++ to encode 108

Hi, thanks for the response.

I've attached ebur128.jpg. It's only 37 k-bytes.
Do you see that first 'shelf' just below LU = -13? I want to boost that the most by percent, maybe
double the power (3 dB). I want to boost LU = 9 not at all, and I want to boost everything below LU
= -14 not at all.
So the transform I want wou

Howdy,
Maybe I don't need 'abitscope'. It's just an experiment when I found that 'oscilloscope' didn't
display audio levels.
I have a 5.1 channel DTS soundtrack. It's the only soundtrack. I want to mux in a new, 2 channel AC3

Howdy,

I need to stream a static image with information on a network to Tv's.

play it as well the TV's. ffplay does play it but complains about

effect. Note t
