These HLLs play .mpg movie files (later games use .alm file extension, but the format is the same, i.e. MPEG-PS) that contain MPEG1 video and MP2 audio streams. pl_mpeg.h is the PL_MPEG library (https://github.com/phoboslab/pl_mpeg) imported from commit 5aeef4d07593be1960a0e4c7fe204809cfae30bd. This adds a few mixer functions (mixer_stream_*) for playing custom audio streams under the master mixer.
