How to save file from filesink in dynamic pipeline

[Dimitrios Katsaros]

What you can do is add a buffer probe to the sink pad of the queue hen you
intend to disconnect once you signal stopping a file. On the next buffer
recieved you trigger the eos event and then do the pipeline cleanup. If you
need to reset the elements for a new recording you can put them to NULL
state and then back to ready/paused/playing. NULL state will ensure that
the EOS flag gets reset and any resources connected with the pipeline (like
the recorded file) are released. Remeber to change the location parameter
on the filesink before setting the pipeline to a higher state than NULL!
