I recently tried some of SomaFM's new HLS streams on MacOS. The stream fails with this error:

../gst-plugins-base-1.18.6/gst/playback/gsturidecodebin.c(1027): no_more_pads_full (): /GstPlayBin:pipeline-1-pipeline/GstURIDecodeBin:uridecodebin0: no suitable plugins found: ../gst-plugins-base-1.18.6/gst/playback/gstdecodebin2.c(4720): gst_decode_bin_expose (): /GstPlayBin:pipeline-1-pipeline/GstURIDecodeBin:uridecodebin0/GstDecodeBin:decodebin1: no suitable plugins found: Missing decoder: application/x-hls (application/x-hls) 

The stream URL is: https://hls.somafm.com/hls/groovesalad/FLAC/program.m3u8

While that is a FLAC stream, any of the HLS streams fails whether they be AAC or FLAC. The non-HLS AAC streams work great as they always have. Based on the error, it appears the HLS bit is the issue.

I'm guessing that some plugin isn't being bundled into the MacOS distribution.
