In SCE_AVPLAYER_AV_SYNC_MODE_NONE every decoded frame was handed out in
order, so a title that requests video slower than the film's frame rate
fell behind its audio (about 52 s by the end of the PPSA12544 intro).
While the title pulls audio, frames the audio clock has already passed are
now skipped; frames that are not late are handed out as before.

A paused player returned no video at all. Unity's video player prepares
a clip by starting it, pausing, jumping to the start and polling
sceAvPlayerGetVideoDataEx until the frame at the jump arrives, and only
then resumes; PPSA12544 waited there forever on a black screen in its
intro cinematic. While paused, the first frame after a jump is now
delivered (the paused clock rebased to it); other frames are still held
until the player resumes. The guest test pauses, jumps and expects that
one frame and nothing after it.

When an application requests only 2 video buffers and holds one during playback, decode-ahead frames allow the decoder to stay ahead and prevent stalls under SyncModeNone.

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).
