An EPG 'slave mode' could check the file timestamp of the EPG file from
time to time and reload EPG on written updates, eg. once a hour or on
master VDR shutdown. Would be a nice low-tech EPG distribution method.
This could even be done by a plugin: VDR runs with -E-, and the plugin
watches the real epg file. From the main loop, the plugin could do
something like this:
time_t lastModified = LastModifiedTime(WatchedFile);
if (lastUpdate < lastModified) {
cSchedulesLock SchedulesLock;
if (cSchedules::ClearAll() && cSchedules::Schedules(SchedulesLock)) {
cSchedules::SetEpgDataFileName(WatchedFile);
cSchedules::Read();
cSchedules::SetEpgDataFileName(NULL);
lastUpdate = lastModified;
}
}
(untested, though)
Now just someone has to write the plugin around it. ;)
Cheers,
Udo
