openjpegenc: store stripe offset when encoding image

The decoder can simply read this offset after decoding

openjpegenc: take subsampling into account when calculating stripe height

We calculate minimum of (stripe height * sub sampling) across all components
to ensure that all component dimensions are consistent with sub-sampling.
The last stripe for each component is simply the remaining height.

adaptivedemux: Don't calculate bitrate for header/index fragments

They are generally substantially smaller than regular fragments, and therefore
we end up pushing totally wrong bitrates downstream.

adaptivedemux: Store QoS values on the element

Storing it per-stream requires taking the manifest lock which can apparenly be
hold for aeons. And since the QoS event comes from the video rendering thread
we *really* do not want to do that.

Storing it as-is in the element is fine, the important part is knowing the
earliest time downstream.

If an error happened switching to a new variant, we switch back to the previous
one ... except it will be unreffed when settin git.

In order to avoid such issues, keep a reference to the old variant until we're

When switching variants, try to re-use existing streams/pads instead of creating
