Unable to play 1080 PVR (.ts) with Audio Unknown - Stutters

1st Official Post

    Hi folks,

    Sorry if this is a repeat of a post - couldn't find where.

    I'm noticing a number of my DVR recordings (from PLEX 1.11.3.4803 on Ubuntu 16.04 LTS 4.4.0-112 generic x86_64 with HDHomeRun Connect and DUAL) are completing with Video 1080P/I - H264 & Audio Unknown - MP2 Stereo.

    Turns out my KODI devices (S905X Chipsets x3) on Libreelec 8.2.3.1 with Plex Add-On 0.1.3 are unable to play these files without stuttering... They're not watchable.

    Otherwise Libreleec / KODI will play pretty well any codec you throw at them with ease (love it!)..

    Any help available to identify why this is the case - or how to determine what the problem is..

    Log file can be found here:

    Perhaps the problem starts here?

    The PLEX client on the PC plays the troublesome files okay.

    Any clues?

    Okay it's not just unknown audio files...

    Recorded one @ 576p with English - MP2 Stereo Audio - it also stutters.

    Same time recorded another @ 1080P - H264 Audio Unknown - MP2 Stereo and it plays fine now.

    PC plays all files no problem.

    Any clues?

    Anyone out there?

    just thinking with you.. have you rulled out the read write speeds of your media? meaning older sdcards have low write speeds especialy when hd stuff...

    Hi!

    I've installed the O/S onto the onbard memory - not the SD Card. There is a noticeable speed difference between the two for sure.

    Thanks for the suggestion though.

    It doesn't seem to be all that uncommon - but there are a number of different resolutions out there, each with subtle nuances.

    I guess I'll have to keep researching. It could very well be memory related though - although it does sometimes happen with 576p content too. At the same time other codecs at 4K are okay.

    Pity, had hoped a guru might be able to decipher the logs and point in the general direction of a resolution.

    Thanks for replying.

    MAYBE solution 1. update to LE9/Milhousebuild (still Alpha!)

    should work solution 2. convert the ts files to mkv (mkvtoolnix) or directly record to mkv

    Hi Folks.

    Okay have done some testing...

    If I load 8.1.8 do a factory reset (delete everything) - everything works properly. MPEG2 files work flawlessly (gee it looks good too!). I use the Plex add-on to test with.

    If I upgrade to 8.2.3.1 it breaks (per the above)..

    I've not done exhaustive testing with other versions - bit frustrated at the time, was just happy to get it going!

    I've tried a few times and I can repliocate it - which is actually a good thing!

    So I'm back onto 8.1.8 (905.arm) which works a treat.

    Sorry for the delay in responding - I'm keen to sort this out. I'll be more diligent in future.

    I guess there's a better thread to post that information into?

    Might get the attention of a broader audience and perhaps get it looked at officially?

    Thanks again folks - I really do appreciate the responses.

    If it was up to me i stay with the best working one.. and if possible make a new image with the latest version 9 on a sdcard and test it, if it works fine, if not, easy to go back..
