Hi again Travis,
I got it working in the end. When I originally tried to review video footage from my Canon 600D on my Google Nexus 7 (2013) I was prompted to install the free version of “MX Player” from the Play Store (it has the usual ads but nothing too bothersome) I assume MX Player is required to stream video from the camera to my tablet but I was only getting black and an eternally spinning wheel.
MX Player – Settings – Decoder (Hardware AND Software)
MX Player needed the correct hardware and software decoder configuration settings for my setup, so I played around with various options and arrived at success through trial and error. I’m not sure of what all the settings options do and It’s probably the case that different cameras paired with other tablets may need alternative settings but the defaults on MX Player did not work in my case.
The streaming playback is very good and easily found in the menus of DSLR Controller.
There is also a DSLR Controller option to transfer the footage from the camera to the monitoring device if needed.
Hope this helps if you still have a need for this function.
Dave
