I' streaming to a Samsung BluRay player with the Samsung C/D Profile. I having some issues with some 1080p rips. They are getting transcoded and I can't figure out why. Here is a comparison of one that works and one that doesn't:

Works:

I see the one that doesn't work has that atom error and the "compatible brands portion is different. Anybody have any idea what the issue is.

One major difference is the one that doesn't work has a captions track. There's some minor differences in the video and audio codecs, but nothing that I think would cause an issue. Try enabling the debug log and see if it identifies the error in more detail.

Ok I removed the captions and it's still getting transcoded. Logs don't provide any details.

Does the compatible_brands line have anything to do with it?

Ok I figured it out, the video has an h264 level of 5.0 and the profile is set to transcode anything greater than 4.2.

I didn't see that in what you posted, only showing High. Yep, if they're 5.0 that profile will transcode. in fact, most profiles will, as there aren't a lot of devices that support levels above 4.1. Those are most likely 4K capable devices.
