Macros
Video Codec Bitmask Constants
Bitmasks for video codec capabilities Each codec is represented by a single bit, allowing multiple codecs to be advertised simultaneously in the codec_capabilities_video field.
#define	VIDEO_CODEC_CAP_RGBA ((uint32_t)(1 << VIDEO_CODEC_RGBA))
	Bit 0: RGBA support.

#define	VIDEO_CODEC_CAP_H265 ((uint32_t)(1 << VIDEO_CODEC_H265))
	Bit 1: H.265 support.

#define	VIDEO_CODEC_CAP_JPEG ((uint32_t)(1 << VIDEO_CODEC_JPEG))
	Bit 2: JPEG support.

#define	VIDEO_CODEC_CAP_ALL (VIDEO_CODEC_CAP_RGBA \| VIDEO_CODEC_CAP_H265 \| VIDEO_CODEC_CAP_JPEG)
	Default video codec capabilities (all codecs supported)

Audio Codec Bitmask Constants
Bitmasks for audio codec capabilities Each codec is represented by a single bit, allowing multiple codecs to be advertised simultaneously in the codec_capabilities_audio field.
#define	AUDIO_CODEC_CAP_RAW ((uint32_t)(1 << AUDIO_CODEC_RAW))
	Bit 0: Raw PCM support.

#define	AUDIO_CODEC_CAP_OPUS ((uint32_t)(1 << AUDIO_CODEC_OPUS))
	Bit 1: Opus support.

#define	AUDIO_CODEC_CAP_ALL (AUDIO_CODEC_CAP_RAW \| AUDIO_CODEC_CAP_OPUS)
	Default audio codec capabilities (all codecs supported)

#define	VIDEO_CODEC_SUPPORTED(cap, codec) (((cap) & (1 << (codec))) != 0)
	Check if a video codec is supported in capabilities bitmask.

#define	AUDIO_CODEC_SUPPORTED(cap, codec) (((cap) & (1 << (codec))) != 0)
	Check if an audio codec is supported in capabilities bitmask.
