typedef void(RENAME(mix_any_func_type))
Describe the class of an AVClass context structure.
const char * class_name
The name of the class; usually it is the same name as the context structure type to which the AVClass...
int extradata_size
Size of the extradata content in bytes.
enum AVMediaType codec_type
General type of the encoded data.
int profile
Codec-specific bitstream restrictions that the stream conforms to.
uint8_t * extradata

int64_t pts
Presentation timestamp in AVStream->time_base units; the time at which the decompressed packet will b...
int64_t dts
Decompression timestamp in AVStream->time_base units; the time at which the packet is decompressed.
New fields can be added to the end with minor version bumps.
unsigned int nb_stream_indexes
unsigned int * stream_index
AVCodecParameters * codecpar
Codec parameters associated with this stream.
int64_t nb_frames
number of frames in this stream if known or 0
int id
Format-specific stream ID.
