Constants

AVIF_ADD_IMAGE_FLAG_FORCE_KEYFRAME	Force this frame to be a keyframe (sync frame).
AVIF_ADD_IMAGE_FLAG_NONE
AVIF_ADD_IMAGE_FLAG_SINGLE	Use this flag when encoding a single image. Signals “still_picture” to AV1 encoders, which tweaks various compression rules. This is enabled automatically when using the avifEncoderWrite() single-image encode path.

AVIF_DECODER_SOURCE_AUTO	If a moov box is present in the .avif(s), use the tracks in it, otherwise decode the primary item.
AVIF_DECODER_SOURCE_PRIMARY_ITEM	Use the primary item and the aux (alpha) item in the avif(s). This is where single-image avifs store their image.
AVIF_DECODER_SOURCE_TRACKS	Use the chunks inside primary/aux tracks in the moov block. This is where avifs image sequences store their images.

avifEncoderSetCodecSpecificOption ^⚠	Codec-specific, optional “advanced” tuning settings, in the form of string key/value pairs. These should be set as early as possible, preferably just after creating avifEncoder but before performing any other actions. key must be non-NULL, but passing a NULL value will delete that key, if it exists. Setting an incorrect or unknown option for the current codec will cause errors of type AVIF_RESULT_INVALID_CODEC_SPECIFIC_OPTION from avifEncoderWrite() or avifEncoderAddImage().
