Apply an aggressive set of ultimately deterministic optimizations to
raster image files where an actual file size reduction of not less than
50% was possible without the removal of intrinsic properties such as
alpha channels. Rendered image dimensions were always left unchanged.
The primary mechanisms employed during optimization are:
- PNG color mode conversion from TrueColor to indexed palette
+ Accomplished using NeuQuant neural-net color quantization algorithm
- Stripping of data blocks containing irrelevant information, such as:
+ XMP metadata fields
+ Embedded comment fields
+ ICC color profiles (simple graphics with basic color schemes only)
+ EXIF profiles
- Re-compression using "best" or "smallest" profile presets
All modifications are performed on lossless image formats and closely
visually inspected after processing to ensure no loss of apparent
details or introduction of new, unwanted artifacts.
Toolset used:
- RIOT (Radical Image Optimization Tool), v2024.1.0 64-bit
- AdvanceCOMP (part of the Advance Projects), v2.6 64-bit
- optiPNG, v7.9.1 64-bit
- PNGOUT, v2015.02.13 32-bit

add mic usage to info.plist
enable micorphone in xcconfig
mic device selection macos
snapshot
revert ios driver
macos only driver, doesn’t deadlock now
macos driver seems to be doing something
looooooop
well, at least it doesn’t spin lock, no audio
audio capture working!
seems to be working now
cleanup some extra logging
clean up some extra logging
rename ios driver for clarity
remove some locks
better performance, but some noise
remove unused fifo_lock
clear the fifo
fix noise in buffer
some improvements, might not need
remove superfulous silent check
reduce latency

* Actually read CLI args in emscripten
* Fix fetchfs manifest parsing, increase download chunk size
The chunk size should probably be made a parameter in the future. The
larger chunk size trades longer hitches for fewer hitches.
* Add exec command driver and API functions for emscripten.
Under WASMFS, stdin/stdout can't be customized the way they can with
the JS FS implementation. Also, this approach frees up stdin/stdout
and simplifies interaction with the command interface for web embedders.
* fixup upload paths, show use of new emscripten cmd interface
* Add JS library function names to EXPORTS as well as EXPORTED_FUNCTIONS for older emsdk versions
