Pausing the pipeline from within a plugin element

[Konstantin Miller]

Dear all,

I am working on a plugin that receives streaming video data and buffers them
in a queue element, which is connected to decodebin. I would like to set the
pipeline to the PAUSED state whenever the queue becomes empty and then
periodically query its current-level-bytes property until enough data is
accumulated to restart playback.

Is it a good practice to call gst_element_set_state on the pipeline from
within a plugin element?

Thanks!

Best,
Konstantin
