Help figuring out why this file is being transcoded
Posted: Sat May 07, 2016 2:35 amVery strange behavior. I tested the file and it plays without transcoding. I can't figure out what it the profile is triggering the transcode. This is for a Roku 2 XS. It supports MKV and MP4 containers with AC3 or AAC audio and H.264 video. Here's the transcoding section of the profile. I've commented out everything I can think of that could be triggering a transcode, but it still does it. This file was created using VideoReDo from a WTV recorded TV file, saving the file as a MKV with H.264 video.
And here's the media Info:

Must have been half asleep. Yeah, that's my excuse!
