Max video bitrate for direct play on Roku?

Recommended Posts

Hi,

 

Though my MediaBrowser app on Roku is set to 20.0Mbps, any movies with bitrate above 14 get transcoded.

Is this the expected behavior?

What would be the maximum bitrate supported by Roku direct play?

 

 

I have browsed the forum but did not find any mention of transcoding due to this scenario.

As a test I joined audio streams of the suspect movie files (the ones with higher bitrates) to low video bitrates and they got played directly.

Also as a test I extracted the audio streams and left only the high bitrate video streams: movies get transcoded.

 

I am running app version 1.78 and server version 3.0.5490.2.

 

Does anybody confirm this behavior?

Luke,

 

Thanks for the quick answer. But let me see if I got it right: video bitrates above 14.0 would be supported on roku IF other aspects were ok.

Is that correct?

 

Would you see any aspect on the mediainfo of such a file that would cause the transcode?

@@EduardoSantos - Since Max Bit rate have been expanded have you tried changing it to 30 Mbps in preferences

 

I think this option will only be available on the new app version (1.79).

I will wait to see if it does the trick...
