How hard can it be to change filesrc location runtime

[marc lievens]

Hi
I already tried this with posting a message and change the pipeline status
to ready and unlinking/linking the decodebin and change of file location
and set back status of pipeline to playing.
I also tried this with unlinking/lining the filesrc with/without previous
one.

Thx ,
marc
