dasVideo

Video playback for daslang: decode a video file to frames plus audio and hand them to your renderer, with A/V sync. A native C++ module plus a small daslang surface — MPEG-1 (pl_mpeg), AV1 (dav1d, as a raw .ivf or in a WebM container alongside Opus audio via nestegg + libopus). Royalty-free, permissively-licensed codecs only.

The design in one breath: the player owns the decoded data, the consumer borrows it through RAII block accessors; audio is the master clock and video is paced to it.
