Re-introduce after the iter5b-α' revert. Helper maps VAProfile to V4L2 OUTPUT-side FOURCC, used at CreateConfig in commit B to populate the previously-dead object_config->pixelformat field. β reads from there at CreateContext (commit C). Single source of truth for the profile→pixelformat mapping; mirrors the per-profile probes in config.c::RequestQueryConfigProfiles (lines 138-188). Register codec.c in meson.build sources, codec.h in headers. Signed-off-by: claude-noether <claude-noether@reauktion.de>
