Hi, I’m facing some real issues when watching a movie with a high bitrate (e.g. 1536) EAC3 audio track in, transcoded to 5.1 AC3 by my Linux PMS. The video gets played smooth, but the audio stutters continuously, and the movie is totally unplayable. I tried to install another PMS from scratch on a…

Version 1.41.4.9463 did not solve this issue.

Version 1.41.5.9522 did not solve this issue.

ALL: You’ve NOT been forgotten. We are testing the new FFMPEG 6.1 for PMS. With this upgrade , we FINALLY should be able to play the high bitrate EAC-3 Might someone be able to provide me a few sample files I can test with? Specifically, I’d like files from normal → high bit rate in increasin…

@deusxanime @lohrtron Might either of you have a high bitrate file for me to use which replicates this? I ask because we think we found the root cause of the problem. We are currently making a special build of the EAE to confirm. I can’t remember, because I didn’t note in the ticket, if this w…

@ChuckPa does this file you submitted with the ticket work? also see the comment above this one i am replying to. the two files still seem active for download.

Thank you. I’ll get on this after dinner Note: 2a27az.mkv, played at 8 mbps, perfectly recreates the stammering problem.

Sounds like you got what was needed then to test it out? I don’t think it was Atmos related as the stuff I noticed the problem with before was just regular EAC3 without Atmos.

We’re good to go now, thanks. We’re making a special debug version of the code so we can track where it’s failing
