If I understand correctly what you want to achieve, I think you are
misunderstanding what videomixer is doing.
It will mix uncompressed streams. So, from the pipeline you showed, you
will have v4l2src -> decoding -> videomixer -> encoding -> stream.
And the RPi is clearly not able to do that.

You want to have multiple streams in one so, mpegts is one of your answers.
And you will have one channel per h264 stream. I think it is doable with
the RPi.

JM
