rtpldacpay

Payload LDAC encoded audio into RTP packets.

LDAC does not have a public specification and concerns itself only with bluetooth transmission. Due to the unavailability of a specification, we consider the encoding-name as X-GST-LDAC.

The best reference is libldac and the A2DP LDAC implementation in Android's bluetooth stack [Flouride] (https://android.googlesource.com/platform/system/bt/+/refs/heads/master/stack/a2dp/a2dp_vendor_ldac_encoder.cc).

Example pipeline

 gst-launch-1.0 -v audiotestsrc ! ldacenc ! rtpldacpay mtu=679 ! avdtpsink

This example pipeline will payload LDAC encoded audio.
