Crash when running example missing gstreamer plugin

[FerroEduardo]

System: Ubuntu 20.04.6 on WSL 2
Kernel: 5.15.90.1-microsoft-standard-WSL2
Script: primeiro-joao/01sync.ncl

Terminal

$ ginga examples/primeiro-joao/01sync.ncl
**
ERROR:PlayerVideo.cpp:95:ginga::PlayerVideo::PlayerVideo(ginga::Formatter*, ginga::Media*): '_audio.pan' should not be nullptr
Bail out! ERROR:PlayerVideo.cpp:95:ginga::PlayerVideo::PlayerVideo(ginga::Formatter*, ginga::Media*): '_audio.pan' should not be nullptr
Aborted

I don't know if this is related to WSL, but I was able to run others scripts:
Pacman

Luarocks

Many thanks @FerroEduardo. Did you have instaled the gstreamer1.0-plugins-bad package in WSL (see here)?
Some decoders are dynamic loaded by gstreamer.

After installing gstreamer packages, I was able to run with success!
Thanks a lot! :)

If helps somehow, I also got this output

This JackShmReadWritePtr is probably a lock issue in the PuselAudio server of WSLg.

This is related to Jack, not PA, and can be safely ignored.
