Description Bastian Krause 2022-11-10 08:27:35 PST

GStreamer 1.16 brought support for planar (non-interleaved) raw audio. Let's use that to simplify the "1 appsrc per channel + audiointerleave" approach to a single appsrc with non-interleaved layout.

We do not need to keep the appsrcs and mapped buffers per channel around which lets us drop a bunch of code.

This approach cuts the overhead the GStreamer pipeline causes on the WPEWebProcess in half on an NXP i.MX 6 DualLite.
