When you create your wav player, with pjsua_player_create, you can also
register a callback function, from pjmedia. This function will be
automaticaly fired when the end of file is reached.
pjsua_player_id player_id = PJSUA_INVALID_ID;
pjmedia_port *media_port;
// create player
pjsua_player_get_port(player_id, &media_port);
// register end of file callback
pjmedia_wav_player_set_eof_cb(media_port, args,
&on_wavplayerEof_callback); ("args" is void* pointer, if you want
to send data, available in the callback function)
This End Of File callback function has to be written this way:
static PJ_DEF(pj_status_t) on_wavplayerEof_callback(pjmedia_port*
media_port, void* args)
{
...
return PJ_SUCCESS;
}
Note that if you want to destroy the player, directly from the callback
function, you need to return anything but PJ_SUCCESS (example: -1).
