Encoding settings for direct play
Posted 13 April 2014 - 08:16 PM
Recently, I noticed that all of my movies are transcoding to the roku. Has anyone had success with settings for direct play on roku?
I want the best quality possible for both DVD and blu ray titles.
I don't have much horsepower on my server, so avoiding transcoding to the roku is important.
Thanks for all the help.

Default bit rate in the MediaBrowser settings is roughly 3 Mbps. Increasing this if you can will help reduce the transcoding needs. If you're using a wired connection, you can go up to 20 Mbps. If you have audio passthru, set the Roku to surround sound. You do this in the Roku's settings. Otherwise, you want to make the 2 channel AAC track the default audio in the container.

Thanks for the quick replies. I do have the max bit rate set to 20 mbs (I have a roku 3 on ethernet)
here is some info for LOTR: the return of the king (DVD):

It still seems to be transcoding.
I want to work on re ripping my entire library to MKV files this summer. Then I want to make new h.264 mp4's for the roku and mobile clients (Since the server now supports multiple versions of each video/episode). Re encoding is going to happen eventually, I would just prefer not to have to do it multiple times for over a TB of MKV's.
I may just have to do some trial and error when I get some free time.

If it is still transcoding when you just click play, can we get the media info from the item. Goto the admin area of the web client. From there select the "Advanced" tab and make sure enable debug logging is checked. If it isn't, check it and save. Not sure if it requires a reset of the server, but it might. Then in the system tray on your server's computer, there is the Media Browser icon running. Right click it and select "Open Library Viewer". Then find that item and copy the Media Streams array. It will look something like this:

Roku is transcoding because it is not capable play back of 59.94006 frame per second content (it is likely that the content is not actually 59.94006 fps it is more likely it is 29ish and interlaced or at least the original source was and that value wasn't changed during your conversion)

TBH I am not sure. I don't know if ffprobe is calculating that value or reading it from the embedded metadata in the file.
You could try running it through mvkmerge gui and changing the fps to see if it makes a difference. (the fps section in the below image)

I'll give that a try. I also noticed that even my DVD MKV's are transcoding. This doesn't have the same frame rate error. Any thoughts?

So I decided to re encode a test file (from the previous MKV). I put it on a flash drive, and it played with the Roku Media Player Channel. Though, when I play it with media browser, it is still transcoding.
The media info is attached.
Thanks for being so patient with my noob questions.
