common internal API header
#define NULL_IF_CONFIG_SMALL(x)
Return NULL if CONFIG_SMALL is true, otherwise the argument without modification.
uint64_t channel_layout
Audio only.
enum AVMediaType codec_type
General type of the encoded data.
enum AVCodecID codec_id

This structure stores compressed data.
int64_t pos
byte position in stream, -1 if unknown
This structure contains the data a format has to probe a file.
unsigned char * buf
Buffer must have AVPROBE_PADDING_SIZE of extra allocated bytes filled with zero.
AVCodecParameters * codecpar
Codec parameters associated with this stream.
int64_t duration
Decoding: duration of the stream, in stream time base.
int64_t start_time
