Does anyone know if one can use GStreamer v 1.20.2 instead of GStreamer 1.16.2 for Processing 4.08b? (video library 4.2.1).

[https://gstreamer.freedesktop.org/releases/1.20/#1.20.2](https://gstreamer.freedesktop.org/releases/1.20/#1.20.2)

bugfixes include: \*\*\* nvh264dec, nvh265dec: Fix broken key-unit trick modes and reverse playback\*\*

I have installed GStreamer yet the P4. video library does not detect it.

Any help is appreciated.
