Playback speed and playbin - do they work together?

[Alexandru Palade]

Thank you, Sebastian. Thanks for pointing me to
gst-plugins-base/tests/examples/playback.
It is extremely interesting, it has the exact same problem I have. If I
tick the loop option the seek bar and position is reported correctly, but
the image is stuck at the last frame from the previous loop. It gets
unfreezed the moment I modify one of the options (like the playback rate or
whatever).

Seeing that you are one of the authors of that example, could you give me
some hints on why that happens?

I appreciate your time.
