e7515971a8 opusdec: Update sink pad templates 
We always require the channel-mapping-field. If it's 0 we require nothing
else, otherwise we need channels, stream-count and coupled count to be
available.

7ec953e085 opusenc: Create an empty taglist if there is none 
There always have to be 2 buffers in the streamheaders, even if
the comment buffer is basically empty.

8a837c6715 opusdec: Handle GstAudioClippingMeta instead of the pre-skip field in the OpusHead 
oggdemux is outputting the meta now, and only outputs if it should really
apply to the current buffer. Previously we would skip N samples also if we
started the decoder in the middle of the stream.

483cb05af1 opusenc: Disable granule position calculations by the base class 
It is doing the wrong thing because of the Opus pre-skip: while the timestamps
are shifted by the pre-skip, the granule positions are not shifted.

oggmux is doing the right thing here already.

f66afc47ac opusenc: Encode exactly the amount of samples we got as input and put correct timestamps on it 
The first frame has lookahead less samples, the last frame might have some
padding or we might have to encode another frame of silence to get all our
input into the encoded data.

This is because of a) the lookahead at the beginning of the encoding, which
shifts all data by that amount of samples and b) the padding needed to fill
the very last frame completely.

Ideally we would use LPC to calculate something better than silence for the
padding to make the encoding as smooth as possible.

With this we get exactly the same amount of samples again in an
opusenc ! opusdec pipeline.

need to check, just let it negotiate and create a new decoder if
needed.

711589ebde opus: Copy metadata in the (de)payloader, but only the relevant ones 
The payloader didn't copy anything so far, the depayloader copied every
possible meta. Let's make it consistent and just copy all metas without tags or
with only the audio tag.

a595874aac opusdec: Fix PLC frame size calculations 
Previously, PLC frames always had a length of 120ms, which caused audio
quality degradation and synchronization errors. Fix this by calculating an
appropriate length for the PLC frame.

The length must be a multiple of 2.5ms. Calculate a multiple of 2.5ms that
is nearest to the current PLC length. Any leftover PLC length that didn't
make it into this frame is accumulated for the next PLC frame.

While Opus always uses 48kHz internally, this information from the
header specifies which frequencies are safe to drop.
