Can not play MKV

[Mikl]

Hello, Duncan


Thank you for the answer.


I can play back video using gst-play-1.0.


Can you be more specific, please,  about how to "them dump the resulting pipeline to a dot file".

It is no options at gst-play-1.0 to dump constructed pipeline in console.

There's a few potential problems here. Rather than figuring out what they are, I'd suggest you just try playing it with gst-play-1.0 first, rather than manually constructing the pipeline. You can them dump the resulting pipeline to a dot file and view it if you'd like to get an idea of how to manually construct.
