RCO menu objects are authored in the PSP movie player's 854x480 FWVGA
framebuffer, not the 480x272 LCD. The renderer was laying everything out in
the wrong coordinate space, which is why no menu items were visible.
- Playlist.streamForPlayListNumber maps the 1-based playListNumber to the
actual stream entry; stream names are not sequential across discs
(The Dark Knight: 00001/00003/00004; The Day After Tomorrow has
duplicate 00002 names).
- CLI menu playback now resolves the correct .MPS file for every region.
- ui module: JavaFX via org.openjfx.javafxplugin + PlayerApp smoke test
(window verified on this display).
- Validated menus + playback on 4 discs: Batman Begins (USA), Jackass
(Australia), The Dark Knight (Europe), The Day After Tomorrow (Japan).
RCO IMG entries hold PNG images (magic 89 50 4E 47), decodable directly
by ImageIO/JavaFX. RcoFile now reads pImgData and stores raw image
bytes in ImageObject; the CLI reports the first image's magic.
- Type system: BaseType (+Int/Float/Unknown) and BaseReferenceType
(+Event/Image/Text/Ref/Object/Model) for typed record fields.
- Object model: BaseObject/BasePositionObject and all 25 object classes
(Page, Plane, Button, UButton, Text, Model, Icon, Group, Action,
XMenu/XMList/XList/XItem, MList/MItem, LList/LItem, IList/IItem,
Progress, Scroll, Spin, ItemSpin, Edit, Clock) with reflection-based
field deserialization.
- ObjectFactory + RcoContext materialize 89 objects and 81 images from
the RCO; RcoFile resolves references and wires entry.obj/vsmxObject.
- Resource builds the live pagetable/animtable/soundtable/texturetable
into the VSMX tree; Controller tracks input focus.
- Validated on Batman Begins: onAutoPlay still drives playback
(stream 00003) with the object tree populated.
The CLI 'rco' command now runs the full pipeline headlessly: parse RCO,
execute the VSMX script, invoke onAutoPlay, and decode the selected
stream via PlaybackEngine. Batman Begins autoplays playlist 3 (the
anti-piracy warning) and decodes 23 frames from stream 00003.
- NativeFunctionFactory resolves script method calls to native Java
methods via reflection; VsmxNativeFunction wraps them for the VM.
- Native objects: Controller, MoviePlayer, Resource, Math, Timer,
GlobalVariables, decoupled from the UI via a MenuHost interface.
- BaseNativeObject.callCallback invokes script callbacks like onAutoPlay.
- CLI 'rco' now wires the full menu and executes onAutoPlay headlessly.
- Validated against Batman Begins: onAutoPlay computes stream IDs and
issues play(playList=3, chapter=1, video=0xE000, audio=0xBD00,
audioFlag=1, subtitle=-1, subtitleFlag=0) — the anti-piracy warning
clip with English video/audio.
- VsmxInterpreter: stack machine executing all 74 VSMX opcodes
(arithmetic, comparisons, bitwise, jumps, calls, arrays, objects).
- Object model: VsmxBaseObject/Undefined/Null/Boolean/Number/String/
Object/Array/Function/Reference/LocalVarReference/Method/CallState/
NativeObject, plus BaseNativeObject for future native objects.
- CLI 'rco' now runs the menu script headlessly and prints the 172
resulting global variables (state, chapter/language config, focus).
- Validated against Batman Begins: script runs with zero unimplemented-
opcode warnings and defines all menu functions (on_cancel, mm_on_push,
trans_to_play, play_movie_beginning, ...).
- Lzr: RLZ decompressor ported from JPCSP (for compressed RCO data).
- RcoFile: parses RCO header, entry tree (labels, VSMX blob, image/
sound/font/object/animation tables, text), and event name table.
- RcoEntrySizes: fixed binary sizes of the 26 object and 11 animation
record types, needed to locate entries with entrySize=0.
- Vsmx: parses VSMX bytecode (code groups + string tables) and
disassembles to human-readable opcodes; VsmxCode holds the opcode
table.
- CLI 'rco' command dumps events, entry tree, and VSMX disassembly.
- Validated against Batman Begins EN/FR menus: full scene graph
(pages/planes/buttons/groups) and 5585-bytecode scripts decoded.
- AnnexBSplitter incrementally splits the Annex-B stream into access
units, holding partial slices across packet feeds.
- VideoDecoder exposes feedAccessUnit and the decoded frame rate.
- PlaybackEngine demuxes and decodes in lockstep, tagging video frames
and audio chunks with 90 kHz PTS (audio from PES headers, video from
PES anchors interpolated by decoder frame rate).
- CLI 'play' command runs the engine headlessly and reports A/V drift.
- Validated against Batman Begins: 95 frames in 4.0s, max drift -78.6 ms
(video trails audio at stream start), avg frame duration 3833.6 ticks.
- Tests for AnnexBSplitter.
- MpsDemuxer parses MPEG-PS packs (0x1BA) into video (0x1E0-0x1EF) and
audio (0x1BD) PES packets with PTS/DTS at the 90kHz clock.
- VideoDecoder decodes Annex-B H.264 via JavaCPP FFmpeg 8.1.2, splitting
the stream into access units (one slice NAL per packet) so each send
yields a frame.
- CLI 'decode' command dumps frame metadata (720x480 YUVJ420P).
- Validated against Batman Begins: 72 frames decoded.
- Parse PS packets, PES headers and PTS/DTS timestamps
- 'mps' CLI command samples packets from a stream
- Validated on Batman Begins 00001.MPS (Annex-B H.264 + 2-channel ATRAC3+)
- Add little-endian readers to UmdIsoFile
- Playlist parser (streams + chapter markers) ported from JPCSP
- dump command now lists streams, durations and chapter markers
- Unit test for chapter/timestamp mapping
