What is the PSS file format?
A .pss file is a video stream container used in PlayStation 2 game discs to store pre-rendered cutscenes and full-motion video (FMV). It is an MPEG-2 Program Stream variant with Sony-specific audio multiplexing, decoded in real time by the PS2's IPU (Image Processing Unit) hardware.
The file begins with the standard MPEG-2 Pack Start Code (00 00 01 BA), identical to MPEG Program Streams and DVD .vob files. The PS2 variant is distinguished internally by custom audio blocks preceded by an SShd header that specifies audio type (PCM 16-bit or SPU2-ADPCM), sample rate, channel count, and interleave size.
Video resolution is bounded by PS2 IPU hardware at 720×480 (NTSC) or 720×576 (PAL). Audio is typically encoded at 44,100 Hz or 48,000 Hz. A small number of PS2 games use WMV2 video instead of MPEG-2, though this is rare.
.pss files are extracted from PS2 game disc images (ISO) using tools such as PSS Plex. VLC media player and the PCSX2 emulator can play most .pss files directly. The format was succeeded by PMF on PlayStation Portable and PAM on PlayStation 3.
Security & safety
RISK: LOWVideo data only, no executable code. PSS files extracted from trusted game ISOs carry no malware risk.
Format details
in a nutshell- Adobe Type Manager PostScript Stub - db_name in our database was 'Adobe Type Manager PostScript stub file' - this is incorrect; that format uses .pss as a PostScript printer description stub, a completely separate and very rare use-case.
Programs that open PSS files
Windows4 apps
VLC media player
Open-source File → Open File, select .pss. VLC handles MPEG-2 PS; audio may partially fail if SPU2-ADPCM. 
PCSX2
Open-source PS2 emulator - plays the full game including FMV sequences; does not open .pss directly but renders them in-game. 
macOS1 app
VLC media player
Open-source File → Open File, select .pss. Same limitations as Windows version for SPU2-ADPCM audio.
