[gst-devel] stopping decodebin before it decodes to raw video

[Michael Smith]

Not with decodebin, no. You can use decodebin2 for this - it has some
signals that the app can connect to to control the autoplugging
process, or for simpler cases you can just tell it what caps it may
output (via a property).
