Queue demux loop epochs and report each once when audio or video first delivers that pass. Discard pending loop boundaries on seek and restart. Add playback regressions and record unverified console callback timing.
AI-assisted: yes (Codex).
Clock::Reset left the paused flag set by Clock::Pause, so a Start issued
from the paused state (stop and restart of the source) kept the clock
frozen at the start position. Only the frame at that position was
delivered; later frames were held back by the default A/V sync.

Waits on eventCondition go through libkernel's TimedWait::Condition (precise
timed waits on Windows) instead of std::condition_variable::wait_for, as
requested in review.
AnyPS5's libc heap registered every block with GPU access, so every
address-based build imported or mirrored each malloc block the title had
made. The console's libc.prx maps its heap with protection 3 (CPU read
and write, no GPU bits), so the GPU never sees it there either.
Heap blocks are now registered without GPU access; reallocating keeps the
block's access. The AvPlayer fallback for a title that passes no texture
allocator stands in for that allocator, which hands out memory the GPU
reads, so it allocates through a new GuestHeapAlignForGpu.

sceAvPlayerAddSource queues an auto start for a player created with auto
start or without an event callback. When the title enabled its streams
and called sceAvPlayerStart before the controller thread ran it, the auto
start called Start again on the playing player, which stopped it, released
every video buffer, including the frame the title held, and started the
film over. guest_avplayer occasionally caught this as "video frame is not
a texture allocation"; right after the test's own start, 8 texture
buffers were released in 15 of 15 runs.
The auto start now starts the player only while it is still ready, and
checks that under the player lock together with the start.
TestAutoStartKeepsStartedPlayback starts a callback-less player itself and
checks that no texture buffer is released afterwards and that the frame
it holds stays allocated. It fails on every run without the fix.
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).
