Unnecessary Transcoding to Xbox 360

[nrlulz]

Hi, I seem to be having a small issue with streaming hd h264/aac content to my xbox 360... it supports that format natively (that is, if I tick "disable transcoding for all devices" and restart the media server, it still plays just fine) but the server seems to be transcoding it anyway. Most of the time I wouldn't mind but it disables seeking so any time I try to skip or ff or accidentally bump a button I get kicked back to the beginning of the movie, so I'm wondering how I would modify my device profile to make it stream those straight over rather than transcoding them.

Here is my ffmpeg output:

Thanks for reporting this. Just to confirm this, please right-click on the video in Mezzmo and click Properties. On the Properties dialog, go to the Transcoding tab and delete any transcoded files listed there. With transcoding turned off, restart your Mezzmo server and try streaming the file to your Xbox 360. If it plays fine, then email us at support [at] conceiva [dot] com and we'll tweak the Xbox 360 device profile to pass this type of video file directly through to Xbox 360s.

Yep, it still works fine. I sent an email. Thanks!

Thanks - got your email. We'll email the updated device profile to you shortly.
