Encoding videos for MPEG-DASH
I would get as far away from EE as possible. Using the x264 tool, and mp4box, you can convert and segment out the files which are ready to be streamed to any dash compatible players. Especially since you mentioned using batch scripts, this is a great solution I think.

This is a good guide: http://www.dash-player.com/blog/2014/11/mpeg-dash-content-generation-using-mp4box-and-x264/
