A RELEASE_MEM with an interrupt select drained the device: the queue
worker submitted everything recorded and waited for the GPU before it
stored the label and delivered the interrupt. PPSA21564 issues about 300
of them per frame, so the worker and the GPU took turns.
The label is now recorded like any other (on the GPU behind the work, or
as a completion action behind pending write-backs), and the delivery
becomes a completion action of the batch holding the work before the
packet (Recorder::AfterRecordedWork, after the batch's earlier
completions). It is counted with the completion labels, so idle workers
and pollers reap it, and it starts the label flush deadline. With draws
or dispatches recorded since the last submit the batch is submitted at
once. A batch holding only label stores stays open and goes out with the
next work, at the label flush deadline, at a wait, at a flip or at the
end of the submission, like any other pending label. A label the GPU
cannot store, or one that does not decode, still drains.
The interrupt so never arrives before the work ahead of it completed and
its label landed; it can only arrive later, by at most the flush
deadline plus the work recorded into the same batch.
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).
Decode VOP3 0x14d and translate it as the per-byte average of S0 and S1,
rounded up where bit 0 of the matching S2 byte is set and truncated
otherwise.

Decode VOP3 0x15a, 0x15b, 0x15c and 0x171 and translate them as the
unsigned sum of absolute differences over the byte or word fields of
the first two sources, accumulated into the third. v_sad_hi_u8 shifts
the sum into the high half first, v_msad_u8 skips the fields whose
reference byte in the second source is zero.

sceKernelSyncOnAddressWait parks the calling thread while the 32-bit word
at the address still holds the expected value, until
sceKernelSyncOnAddressWake releases it or the timeout expires.
sceKernelSyncOnAddressWake releases up to the requested number of threads
parked on the address, in arrival order.
The libc.prx bundled with SDK 9 titles imports both for its once
primitive, so those titles stopped at load with an unresolved import.
# Conflicts:
# docs/dev/TechnicalDebt.md
libkernel did not export sceKernelMapNamedFlexibleMemoryInternal, which
the libc bundled with SDK 9 titles imports. It now forwards to
sceKernelMapNamedFlexibleMemory: the mapping counts against the flexible
budget, gets the range name and is released by sceKernelMunmap. Older
libc builds call the public function at the same sites with the same
arguments and result handling.
The known callers pass flag 0x8000, whose meaning is unknown. It is
still rejected as an unsupported mapping flag and is recorded in
TechnicalDebt.

scePngEncQueryMemorySize, scePngEncCreate, scePngEncEncode and
scePngEncDelete encode R8G8B8A8 and B8G8R8A8 images with a pitch into
RGB or RGBA PNGs using the shared encoder in core/Decoder/Png.
Decoder::Png::Encode takes optional compression level and filter
options so the encode parameters are honoured.
