I should polish this by adding more checks on GStreamer and tweaking defaults.

What's the implication of disabling this in playbin? In the player we set a custom text-sink to collect in-band text cues, should that code be ifdeffed now?

Text sink pads get not connected to anything in playsink so text dies there.

So this unsets the default flags too, which is not a great idea, the default is "soft-colorbalance+deinterlace+soft-volume+text+audio+video". Can you get the previous flags before and preserve them please?
