Since I'm not familiar with meson build system, I'll prepare it after studying
about it :)

MSE is one of my future use-case. However, the most urgent use-case on my side
is MPEGDASH/HLS based streaming/broadcasting with playbin but without
adaptivedemux element. For that services, I've used external module. A role of
the external module is to download fragmented MP4/MPEGTS media segment, and
feed it to playbin pipeline. It can be imaged that like generic DASH/HLS
pipeline but adaptivedemux is omitted.

Anyway, content providers asked dynamically changing streaming environment
nowadays, such as 
- video/audio codec change (e.g., with AD insertion)
- insertion of subtitle track during playing (e.g., broadcasting). 
And maybe, unexpected removed track can be possible especially broadcasting
system.

So, to support that features, we need very flexible source element.
