Function Documentation

int ff_asf_get_packet ( AVFormatContext *  s,
ByteIOContext *  pb 
)

Load a single ASF packet into the demuxer.

Parameters:
s demux context
pb context to read data from
Returns:
0 on success, <0 on error

int ff_asf_parse_packet ( AVFormatContext *  s,
ByteIOContext *  pb,
AVPacket *  pkt 
)

Parse data from individual ASF packets (which were previously loaded with asf_get_packet()).

Parameters:
s demux context
pb context to read data from
pkt pointer to store packet data into
Returns:
0 if data was stored in pkt, <0 on error or 1 if more ASF packets need to be loaded (through asf_get_packet())
