I noticed that there are Roku solutions that use a Windows PC to run a 
transcode to h.264 and serve as a go between for the Mythtv and Roku.  I 
don't see why I can't setup an automatic job to transcode and leave the 
files in place as a part of the database on the backend.  I would just 
need a Roku frontend that could talk to the mythtv backend.  I find that 
commercial detection is about 90% effective and that last 10% can drive 
you crazy during playback, so having the 30 second skip is about all I need.

I find all the transcode scripts that use Handbrake or ffmpeg are broken 
in 0.28 and have reported the bug in mythtranscode, so I will have to do 
this in 0.27. I could modify the script at: 
https://www.mythtv.org/wiki/Transcode_Mpeg2_to_H264

or https://forum.mythtv.org/viewtopic.php?f=2&t=1261

but these scripts transcode lossless mpeg2 to mpeg2 to another location 
and apply commercial detection prior to mpeg2 to mp4 transcoding with 
Handbrake/ffmpeg.  mythtranscode with the -o option is where the bug is.


Because I have a Logitech Harmony Smart Control I think I can setup a 
one button control to switch between, my Kodi frontend computer and the 
Koku.  I have the Harmony completely controlling the Kodi. If I can do 
the same with Roku, I could make this seamless for the wife and avoid 
the transcode
