When playing current unity games like Desperados 3 gstreamer complains about
missing a decoder for h264.

Missing decoder: MPEG-4 AAC (audio/mpeg, mpegversion=(int)4,
framed=(boolean)true, stream-format=(string)raw, level=(string)2,
base-profile=(string)lc, profile=(string)lc, codec_data=(buffer)1190,
rate=(int)48000, channels=(int)2)
Missing decoder: H.264 (Main Profile) (video/x-h264, stream-format=(string)avc,
alignment=(string)au, level=(string)4.1, profile=(string)main,
codec_data=(buffer)014d4029ffe10019674d4029965280f0044fcb3501010140000003004000000ca101000568e9093520,
width=(int)1920, height=(int)1080, framerate=(fraction)25/1,
pixel-aspect-ratio=(fraction)1/1)

Probably the packages need to depend on the proper gstreamer package or at
least reccomend them.

This was experienced in Ubuntu 20.10.
