Define Documentation

#define AVSEEK_SIZE   0x10000

Passing this as the "whence" parameter to a seek function causes it to return the filesize without seeking anywhere.

Supporting this is optional. If it is not supported then the seek function will return <0.

int av_url_read_pause ( URLContext *  h,
int  pause 
)

Pause and resume playing - only meaningful if using a network streaming protocol (e.g.

MMS).

Parameters:
pause 1 for pause, 0 for resume

Definition at line 232 of file avio.c.

int64_t av_url_read_seek ( URLContext *  h,
int  stream_index,
int64_t  timestamp,
int  flags 
)

Seek to a given timestamp relative to some component stream.

Only meaningful if using a network streaming protocol (e.g. MMS.).

Parameters:
stream_index The stream index that the timestamp is relative to. If stream_index is (-1) the timestamp should be in AV_TIME_BASE units from the beginning of the presentation. If a stream_index >= 0 is used and the protocol does not support seeking based on component streams, the call will fail with ENOTSUP.
timestamp timestamp in AVStream.time_base units or if there is no stream specified then in AV_TIME_BASE units.
flags Optional combination of AVSEEK_FLAG_BACKWARD, AVSEEK_FLAG_BYTE and AVSEEK_FLAG_ANY. The protocol may silently ignore AVSEEK_FLAG_BACKWARD and AVSEEK_FLAG_ANY, but AVSEEK_FLAG_BYTE will fail with ENOTSUP if used and not supported.
Returns:
>= 0 on success

int udp_set_remote_url ( URLContext *  h,
const char *  uri

If no filename is given to av_open_input_file because you want to get the local port first, then you must call this function to set the remote server address.

url syntax: udp://host:port[?option=val...] option: 'ttl=n' : set the ttl value (for multicast only) 'localport=n' : set the local port 'pkt_size=n' : set max packet size 'reuse=1' : enable reusing the socket

Parameters:
