328f9088f3 opusenc: Add GstAudioClippingMeta to buffers that need to be clipped

6b751360ae 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.

4df2ffaad6 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.

7cadfcb0b0 opusenc: Place 48kHz first in the caps 
For all the other sample rates the encoder will have to resample internally.

54a5859960 opusdec: remove check for number of channels 
opus decoder can convert from different number of channels, no
need to check, just let it negotiate and create a new decoder if
needed.

Safer, easier to understand, and more portable. Also, skip
all this if the log level is too low.

e5409361b8 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.

ef29b92990 opusdec: Take output sample rate from the stream headers too 
This way we let opusdec do the resampling if needed and don't carry
around buffers with a too high sample rate if not required.

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

80df2cb063 opusenc: increase max payload size to 4000 bytes 
1275 is the maximum size of a frame, but the encoder may return
up to 3 frames, and we need a few extra bytes for TOC, etc. We
use 4000, which is a bit more, and suggested in the libopus docs.
