Unnecessary Transcoding

nickp85nickp85 Posts: 18Members ✭✭

Within the past few versions of PMS, I am seeing an issue with my Apple TV where an mkv file which should play just fine with direct stream is being transcoded from H264 to H264 and audio from AAC to AAC. I end up having to stop it, optimize the file for TV and it just converts it to mp4 but video and audio all look the same. How come direct stream seems to have gotten flakey in the last few releases?

Here's an example video file info:
Original MKV:

Now can someone tell me why this wouldn't directstream and instead attempted to transcode? My little QNAP can't handle transcode so i rely on Direct Play and Direct Stream for everything. This issue is with my Apple TV 4 and now my new Apple TV 4K. iOS has the same issue with the original MKV. I have my quality settings to maximum in all places.

Attaching my PMS logs too taken right after attempting to place this MKV file and it failing. Other MKV work fine, not sure why some are being finicky.

Thanks

    I am having the same problem.
    After switching to an Apple TV 4k I started getting transcodes all the time!
    I verified this with old videos that I know didn't transcode on my old ATV, and now they do.

    Really annoying!

    Nope

    @dragonmel thanks, hopefully there’s updates coming to fix this stuff. Been very disappointed in Plex lately after at least three years of use.
