EMS operation

1: Currently if we restart Evostream and any Stream not working for that moment from the configured list then it discard and doesn’t play later if stream works fine and it removes that stream from PushpullSetup.xml file. We wanna keep that stream saved in file so that we don’t need to add it again and again. 2: Some times due to network latency / interruptions we get delayed ( buffered ) stream but in case if we want to view only live stream and don’t want to buffer while its coming from evostream to us via RTMP then how to configure. 3: If we want to keep recorded video files for particular time like 1 hour then is it possible in evostream ? if yes then how to configure. 4: Is it possible to get thumbnail image from any stream ?
