Function Documentation

AVVorbisParseContext* av_vorbis_parse_init ( const uint8_t extradata,
int  extradata_size 
)

Allocate and initialize the Vorbis parser using headers in the extradata.

void av_vorbis_parse_free ( AVVorbisParseContext **  s)

Free the parser and everything associated with it.

int av_vorbis_parse_frame_flags ( AVVorbisParseContext s,
const uint8_t buf,
int  buf_size,
int flags 
)

Get the duration for a Vorbis packet.

If flags is NULL, special frames are considered invalid.

Parameters
sVorbis parser context
bufbuffer containing a Vorbis frame
buf_sizesize of the buffer
flagsflags for special frames

int av_vorbis_parse_frame ( AVVorbisParseContext s,
const uint8_t buf,
int  buf_size 
)

Get the duration for a Vorbis packet.

Parameters
sVorbis parser context
bufbuffer containing a Vorbis frame
buf_sizesize of the buffer
