pseudocode scraped off H.264 spec (2024/08)

h264-pseudocode.js

// pseudocode contained in H.264 spec syntax tables:
// - category column becomes a /* C = ... */ comment
// - descriptor column becomes `= DESC('...')`
// - added missing { or } in a few places
// - remove space in "| |" "= =" "! =" "- -" "< =" "> ="
// - prepend _ to 2 identifiers beginning with "3d"
// - prepend "function" to each table
