gst_query_set_nth_allocation_pool() requires there to be a pool in the
query already. This is not always the case when we get the query from
upstream.  Use gst_query_add_allocation_pool() instead in such case.

Use the mapper to set the delta-unit flag.

When we get a new buffer, always call the parse function, even if it is a 0
sized buffer. For theora we need to also decode 0 sized buffers.
Ideally we would like to make theoradec be packetized but that fails currently
because of oggdemux and because of the assumptions that the base class makes.

Should not be empty but might be when we actually pass and decode the 0 packets
later.

Instead, remember we need a keyframe, and we will force the encoder
to emit one next time we submit a new frame.
Since libtheora does not have an API to request a keyframe, we reset
the max keyframe interval to 1 temporarily.

This has the advantage that the rate control keeps its history,
and that the encoder won't choose different quant tables or
somesuch, thus requiring new streamheaders (although this is
probably only a theoretical possibility). Should also be a
bit faster than resetting the encoder.

Clamp timestamp interpollation to 0 to avoid going negative. This should not
happen, really, but until the interpolation is improved this seems better.

When doing reverse playback the positino advances from timestamp_end to
timestamp.

This allows getting a pad for a specific encoding profile, which can
be useful when there are several stream profiles of the same type.

Also update the encodebin unit tests so that we check that the returned
pad has the right caps.

Use only one matrix function pointer, let the implementation cast the pixels to
the right size.

Use only one temporary array for pixels.

This makes sure that they're unlnked and don't cause any errors or
block the pipeline.

Pass them to all possible sinks and the current sinks to
allow elements to chose a more optimal initial caps.

This allows playbin to answer the CAPS query with the possible sink
caps for example, and allows decoders to chose more optimal caps.

This can happen if a demuxer does not provide fixed caps from the
beginning but only sets them later.

Before it was done the other way around and that can trigger the assert that
already is in place. This also makes more sense; when seeking to time x, we want
then sample that is <= that pos.

This allows elements to specify a function to upload
a buffer content to a specific OpenGL texture ID. It
could be used by the vaapi elements to provide a way
for eglglessink or WebKit to upload a VA surface to
an GL texture without the respective sinks knowing
anything about VA.

The test now passed a few rounds of nice -n19 make elements/adder.torture.

Packing is supposed to happen on the amount of lines specified in the format
info. It's currently all set to 1 but that will change.

Try to select the conversion that would result in the minimal amount of quality
loss. Quality loss is calculated rather arbitrarily but it avoids doing
something really stupid in most cases.

This is dead since ~6 years.

Drop channel-mask as we only do mon/stereo and channel-mask is optional in these
cases.

Add GST_RIFF_TAG_note for wavparse.
