PS5 titles pass a 0x230-byte SceAvPlayerInitDataEx: auto start is the
byte after debug_level at 0x74, nine 0x30-byte thread parameter blocks
fill 0x78-0x228 and the output video frame buffer count is at 0x228.
sceAvPlayerInitEx read both fields at their PS4 offsets: auto start at
0xa8 is the video decoder thread priority and the buffer count at 0xa4
lies in the audio decoder block. PPSA25063 (Poppy Playtime: Chapter 4)
sets every thread priority to 700, so its intro video started on its
own and stopped at once; it writes auto start 0 and starts playback
itself.
With this_size 0x230 or more both fields are read at the PS5 offsets;
smaller structures are read as before. The layout follows KytyPS5,
prosper, SharpProspero and sharpemu and is recorded in TechnicalDebt.
guest_avplayer builds a 0x230-byte structure with auto start 0 and
nonzero thread parameters, then with auto start 1, and checks when
playback starts and how many video buffers are allocated.

Replace the decoder-less AvPlayer with a player that demuxes MP4 sources
with FFmpeg (opened by path or through the title's file replacement),
decodes H.264 and AAC on their own threads, and hands out NV12 frames and
interleaved 16-bit PCM in buffers from the title's allocators, presented
on a media clock that audio drives when it is enabled.
Both libSceAvPlayer and libSceAvPlayer.native are built from the same
sources and link the shared ffmpeg target. The struct size checks stay,
next to the types in SceTypes.hpp. ChangeStream and GetStreamInfoEx are
implemented; Init without allocators, StartEx, SetAvailableBandwidth,
SetLogCallback and negative trick speeds succeed as before and are listed
in TechnicalDebt. HLS sources throw.
guest_avplayer plays an embedded 6 KB MP4 (H.264 plus two AAC tracks).
Replace the stub AvPlayer export set with a general-purpose player state
machine covering the full API surface: sceAvPlayerInit/InitEx/PostInit,
AddSource/AddSourceEx, Start/StartEx, Pause/Resume/Stop/Close, IsActive,
CurrentTime, JumpToTime, SetLooping, SetAvSyncMode, SetTrickSpeed,
SetAvailableBandwidth, StreamCount/EnableStream/DisableStream/ChangeStream/
GetStreamInfo(Ex), and GetVideoData(Ex)/GetAudioData.
No real decoder is wired up: the player tracks lifecycle and timing state
and serves a fixed-length blank clip on a wall-clock media clock, firing
the READY/PLAY/PAUSE/STOP event callbacks a title expects from a real
playback session. This is enough for titles that gate progression on
AvPlayer's polling/event surface rather than on decoded frame content.
The non-native libSceAvPlayer/Export.cpp now forwards to the native
implementation via #include rather than carrying its own duplicate stub
definitions, consistent with how other libSceX/libSceX.native pairs in
this tree share one implementation.
