Cool

nice work as always subjunk look forward to it going final.
Cheers, it should be very soon, I'm hoping to also include the fix for external subtitles on Samsung TVs in this release if we can narrow it down in time. I have to go away for a few days on Wednesday so hopefully we can squeeze in the release before then

Thanks for the info Wolfgan

I checked in 3.6.4 and it also detects mp4 as mov initially so I don't think that's related, from what I can see we update our information later on and correctly realize it's mp4 and not mov. Does the version I posted (

Thx, but it didn't work for me. In fact the logs submitted were generated with that specific build and I have no clue on why UMS refuses to serve the file instead opting for transcoding it.
I'll try to investigate it further and feed back. Thanks!

Can you post logs for it? If it's on PS3 then it's a different possible issue

The PS3 supports MP4s with the following combinations:
mp4 or h264 video with ac3 audio
mp4 or h264 video with aac audio with only 2 channels
So possibly your MP4 has AAC audio with more than 2 channels?

the issue that Wolfgan is describing might be the same as a new issue I have raise in the tracker.
I've noticed that some MP4 files with AAC audio are incorrectly being detected as LPCM, and therefore they end up getting unnecessarily transcoded.

I reinstalled UMS from scratch with latest 4.0.x build from Master branch and now it seems to work as expected based on the formats supported (both PS3 and WDTV tested). I'll keep testing and report if anything sounds suspicious.
Thx, Wolf
