Hi,
most of DVR's have the function to stream live video, you can mostly view this video online in your browser.
But how you can see the playback stream? I need to integrate the playback data with my system, i need to build web app which allow me to play recorded video, based on choosed time, for example this Monday from 7 to 8 i need to play something like 10.0.0.200/playback.htm?from=2015-12-01 07:00:00&to=2015-12-01 08:00:00.
Can somebody suggest me the right DVR or some linux app which could stream this data for me? All DVR's are linux based, can you give me some tips? how to achieve something what i need?
