I kinda new to this but I have a 4K tv, a LG 77UH, I can use UMS for every 1080P file, but I cannot play 4k.
If I plug the HDD to the TV the 4K file plays np.

You can try to add to your LG-WebOS.conf the
Code: Select all
MaxVideoWidth = 3840
MaxVideoHeight = 2160

Please can you reproduce the bug (trying to play the 4K video) and provide the log? I would like to see the communication between UMS and TV.

The problem is that your 4K video has DTS-HD audio which is not supported by the TV (is not set in the .conf) and the video is transcoded. There is also other other problem because there are two video streams in the media file and both are transcoded into one output stream with the FFmpeg parameter
which in fact should be
. This is a bug in the UMS.
Can you try to use the .conf I provided and after test send the log?

Sorry to bother you with this =(.
Same deal but this time the TV was "loading" for a bit longer before showing the error.

OK. Now the TV is asking for the video without transcoding. If the TV still shows error could mean that this media format is not supported via DLNA but is supported from HDD which is common problem. There could be also problem somewhere else. Seems to me that even if the video file extension is
in fact it is an
format. Can you provide the MediaInfo output for that file? Do you have any other 4K video you can test?
