Module decode 

Decoders for the client camera uplink, and for the checks that read a session’s own output back.

Clients send whatever their browser can produce: H.264 (WebCodecs or the WebRTC media track), VP8/VP9/AV1/HEVC (same sources), or MJPEG from the canvas fallback. Every codec lands in the same I420 view so the rest of the pipeline is codec-agnostic. H.264 decodes through Cisco OpenH264, VP8 and VP9 through libvpx, AV1 through dav1d, HEVC through libde265, and MJPEG through TurboJPEG, which pixelflux already uses for its own JPEG stripes. Decoding is software here; a hardware decoder only changes which Decoder is constructed.

Structs

ColorTags

The color a decoded stream declares: the matrix as ISO/IEC 23091-2 codes it (1 BT.709, 5 BT.470BG, 6 SMPTE 170M, 2 unspecified) and whether the range is full.

JpegDecoder

TurboJPEG decoder: 4:2:0 JPEGs decode straight into I420 planes; other subsamplings take the RGB route and are converted.

VideoDecoder

A software decoder for one of the inter-coded codecs.

Functions

sniff_keyframe

Whether an encoded frame is a key frame, read from the bitstream itself: every codec here declares it in its first bytes or NAL types.
