aye...here mark should chime in and provide that information.
what we did was basically:
<snip>
m_file = bgav_create();
if(!m_file) return false;
m_opt = bgav_get_options(m_file);
if(!m_opt) return false;
bgav_options_set_seek_subtitles(m_opt, 0);
bgav_options_set_sample_accurate(m_opt, 1);
bgav_options_set_log_callback(m_opt,
log_callback, this);
if(!bgav_open(m_file, filename)) {close(); return;}
</snip>
and we never survived the last line...
