This struct describes the properties of an encoded stream.
enum AVMediaType codec_type
General type of the encoded data.
int block_align
Audio only.
uint8_t * extradata
Extra binary data needed for initializing the decoder, codec-dependent.
enum AVCodecID codec_id
Specific type of the encoded data (the codec used).

Audio only.
This structure stores compressed data.
This structure contains the data a format has to probe a file.
int buf_size
Size of buf except extra allocated bytes.
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
Decoding: pts of the first frame of the stream in presentation order, in stream time base.
