change uri from uridecodebin3

[Jon bae]

Hello everybody,

when I use a playbin in python I can switch the input uri with:

playbin.connect('about-to-finish', on_about_to_finish)

I saw that uridecodebin3 have also an "about-to-finish" signal... But when I try with that to switch the input I get only errors and nothing is happen.

Is it not possible to switch the uri in uridecodebin3?

Is it not possible to switch the uri in uridecodebin3?

I can answer my self now: first I have to change the state from uridecodebin3 to READY, and then I can change the uri.

For me this feels strange that I have to set the state from the whole bin to READY, that means for a moment the element stops playing?! Does this not end up in very little breaks, every time my script change the uri?
