Missing element: MPEG4-GENERIC audio RTP …
https://stackoverflow.com/questions/59854620/missing-element-mpeg4-generic-audio-rtp-depayloader-gstreamer
There are two different MPEG4 audio RTP formats in the wild. MP4A-LATMand MPEG4-GENERIC. See RFC 3016and RFC 3640respectively. Looks like GStreamer only supports MP4A-LATM. So basically, yes, the format you are trying to receive is not supported. Share.

Authors: B. Grill, S. Quackenbush. MPEG-1 Layer I or II Audio is a generic subband coder operating at bit rates in the range of 32 to 448 kb/s and supporting sampling frequencies of 32, 44.1 and 48 kHz. Typical bit rates for Layer II are in the range of 128 …
Advanced Audio Coding - Wikipedia
https://en.wikipedia.org/wiki/Advanced_Audio_Coding
The MPEG-4 audio coding algorithm family spans the range from low bit rate speech encoding (down to 2 kbit/s) to high-quality audio coding (at 64 kbit/s per channel and higher). AAC offers sampling frequencies between 8 kHz and 96 kHz and any number of channels between 1 and 48.
MPEG Audio FAQ: MPEG-1 - Massachusetts Institute of Technology
https://sound.media.mit.edu/resources/mpeg4/audio/faq/mpeg1.html
MPEG-1 audio aims for generic sound waves, i.e. it is not restricted to e.g. speech signals, but codes all types of sound signals. It performs perceptual audio coding rather than lossless coding. In lossless coding, redundancy in the waveform is reduced to compress the sound signal, and the decoded sound wave does not differ from the original ...
