Detailed Description

Zero-copy JPEG passthrough codec backend.

Tag: [Ring 4 / Service] {World: NS}

A source which already produces complete JPEG frames should not be decoded and re-encoded. This codec validates that the input format is JPEG and returns an exact view of the same bytes without using output storage.

ra8_err_t ra8_camera_codec_passthrough_init ( ra8_camera_codec_t * codec )

nodiscard

Bind the zero-copy JPEG passthrough codec.

Parameters

[out] codec Caller-owned codec handle to bind.

Returns: ra8_err_t Error code.

Return values

k_ra8_ok	Codec bound.
k_ra8_err_null_ptr	codec was NULL.

Precondition: codec out-lives every codec operation.; The caller does not mutate the handle while encoding.

Postcondition: On success JPEG input is returned byte-for-byte without copying.; On error no state is modified.

Note: Stateless; independent handles are thread-safe.
