tee won't go in playing state

[philippe renon]

Adding async=false to the filesink works. The pipeline goes to running state.
I will try the other suggested solutions.

The problem here is that by default, x264enc has ~3 seconds of latency
and queue only has space for 1 second.

Either increase the queue limit (at the non-x264enc branch) to more
than 3 seconds (and disable the buffers/bytes limits), or change the
x264enc settings to have a lower latency (e.g. tune=zerolatency).
