Per-axis size caps let AV1 accept 65536x65536 frames (over 8 GiB of luma)
and did not count references or pictures in flight. A shared budget module
in deckcraft-bitstream sizes a picture with checked arithmetic, and the
AV1, VP9, HEVC and H.264 decoders refuse a picture size whose current
picture, reference slots and in-flight pictures would exceed 4 GiB (1 GiB
on 32-bit), before allocating. set_memory_budget lowers it for hosts and tests.

- crates/media: probe (duration, rate/channels, size/fps; WMA/WMV recognised), audio decode to
f32 PCM (MP3, AAC M4A/ADTS, ALAC, WAV, AIFF, CAF, FLAC, Vorbis via symphonia; Opus with our
decoder in Ogg/WebM/MKV), video decode (MP4/MOV/WebM/MKV) with YUV->RGBA, poster frames,
trim/fade/volume, Player mixer + per-voice clock (device-clocked or wall-clocked), VideoFeed.
- Codec crates ported from FilmCraft: bitstream, h264, hevc, vp9, av1, isobmff, matroska, ogg, opus.
- insert.audio/insert.video probe and store duration/size and a poster frame; unplayable media
is embedded with a warning. New media.play/pause/toggle/stop/seek/info/posterFrame.
- UI: MediaHost (cpal output injected by the desktop app), control bar under media, video frames
on canvas and in the show; autoplay, click to play, loop, rewind, across slides, hide, full screen.
- Tests with in-code WAV/AIFF and CC0 self-generated fixtures (make.sh, ATTRIBUTION.md rows).
