It is (probably) rarely used part of h264 MVC standard. As such, I doubt there is any available decoder who can even read it.

Furthermore to my knowledge, dependent view MVC elementary stream is not supported by MKVToolNix.
Author said in past that he will implement it if there will be demand but he wants to do it right.
Nowadays with decline of 3D I'd say there won't be any demand anymore. There are also no more mediaplayers capable of 3D.
Pity...

Thanks for your answer.
