How to split a mkv(AVC+AAC) file to pure video and audio files by using gst-launch?

[Raymond18]

Thanks a lot.

BUT..
# gst-launch-0.10 filesrc location=/home/test.mkv ! matroskademux !
h264parse ! matroskamux ! filesink location=from_matro_h264.mkv 

The above command will generate a mkv format file as following.
------------------------------
$ mediainfo from_matro_h264.mkv

It doesn't work.
