How can i force to end all streams (or pipeline) at a specific timestamp

[Nicolas Dufresne]

That's because this pipeline is not live, the video data will be
accumulated in the queue, so when you send eos, you may be ahead of
time on the audio. You may drop the queues (might not be perfect, but
it's simple), or use a pad probe to monitor each src position. When the
time of the produced buffer is passed the range you want, you can send
eos on that branch.

The being said, you need to track segment event, and use that segment
to convert the timesteamp in something meaningful (running time or
stream time, depending on what you really want).

good luck,
Nicolas
