Play mpeg2 without hw acceleration in rapsberry pi 3B +

[calanor]

I running vlc 3.0.3 Vetinari in raspberry pi model 3 B+.

Vlc plays perfectly videos and streams x264 to full Hd using the mmal hw acceleration
But it is not capable to play SD videos in mpeg2 format correctly. I see that vlc try to use mmal for mpeg2 reproduction but my raspberry pi do not have the license for mpeg2 hw decoding.

It is assumed that the 3 B+ model has enough cpu to decode mpeg2 streams by sofware but I can not find the option in commandline to deactivate the hw acceleration. Vlc uses always mmal decoding.

I'ts possible play mpeg2 without hw acceleration in rapsberry pi 3B +?

Thank you,
