PMF

PMF or "Playstation Movie Format" (or "Playstation Media Format") is a media container used for in-game FMV as well as for icon animations in VSH.

The PMF container consists of a 2KiB header and an MPEG-2 Program Stream containing h.264 video and optionally audio in ATRAC3plus format.

ffmpeg has support for demuxing PMF files and they can also be played in VLC.

To play these videos on the PSP, the libpsmfplayer.prx library can be used
