Crate rff_codec 

rff-codec — the codec abstraction layer (FFmpeg’s libavcodec core, minus the codecs themselves).

It defines:

• the Decoder and Encoder traits, using the same send / receive shape as modern FFmpeg (avcodec_send_packet / avcodec_receive_frame),
• a Codec descriptor that advertises a codec’s identity and which directions (decode/encode) it supports,
• a CodecRegistry that individual codec crates register into.

Concrete codecs live in their own crates (rff-codec-h264, …) and are pulled together by the rff facade.

Structs

Codec

Static description of a codec and the implementations available for it.

CodecParams

Stream parameters handed to a decoder before the first packet. Self-describing codecs (AV1, PNG, …) can ignore these; raw/parametric codecs (PCM, and codecs that carry config out of band like H.264 SPS/PPS) need them.

CodecRegistry

Holds every codec known to a running engine. Codec crates call register to add themselves.

Traits

Decoder

Decodes compressed Packets into raw Frames.

Encoder

Encodes raw Frames into compressed Packets. Mirror of Decoder.

Type Aliases

DecoderFactory

Factory function producing a fresh decoder instance.

EncoderFactory

Factory function producing a fresh encoder instance.
