Video Corruption on Remux

[JeremyG 30]

I have a number of UHD videos with TrueHD.   TrueHD needs to be remuxed to be played on my Roku Ultra.    For some movies this works just fine.   For others, i get video corruption when the audio is being remuxed (but video is direct).   With the exact same file, if I choose an audio track like "English Stereo" it goes to directplay and everything is fine (but sounds like crap)

If i fast-forward into the movie, so parts get remuxed with no video corruption...but other parts do. 

This happens whether Hardware transcoding is enabled or diasabled.

Any idea what this happens?

HI, this may be improved following the 4.7 release of Emby Server. Thanks.

Is there some way to force them to transcode (instead of remux) so that i can watch them at least?

Specify a lower quality in the client.  If you specify a bitrate lower than that of the media, transcoding is used to generate a stream at the lower bitrate.

If you bring up the OSD during playback and click the gear you should have an option called Playback Correction that changed playback method depending on how many times clicked.  But for a remux one click should change to transcode.

Awesome things, I didnt know this!

You could also just replace your playback device?

But there are topics on every client/app having some sort of issue in a HEVC audio transcode environment.  Or just ensure your media is Direct Playable per your owned device.

 I don't want to lose the TrueHD audio track (cause one day hopefully it will be supported on players).   But I guess I *could* take all my videos and re-package them and include one track where TrueHD is recoded as 5.1   But that would be a very time-consuming process!

I don't believe there are any for the Shield, nor for PC, but I could be wrong and it would not be the first time.  Though I do agree to ensure that your media is Direct Playable on your devices.

What are you using to remux the files ?

In using the latest mkvtoolnix (v63/v64), I have not had any experience in adding/remuxing THD or DTS-HD including adding an AC3 default track - which is I suspect what you are trying to do / need to do ?

But as all above have said, transcoding any form of UHD is a lucky dip - so the 'time consuming process' may be your only option if you want hassle free UHD playback - or buy clients that can natively play the HD Audio (Shield Pro etc..).

Hi.  If you are running the beta server then you can test if this is improved with the current beta of the Roku app.

Please let us know.

Thanks.

Still not right, but "getting better".  Will provide some specific feeback in the Roku beta area.
