Rocketman playback keeps halting

[Lonald 10]

Hi all,

 

The Rocketman Blu Ray keeps halting during playback, though it plays fine using external players like Leawo and Kodi.  This is occurring with both the Emby theater app for Windows as well as through the Web app on Google Chrome.  The Theater app is using Direct play and the web app is using Direct Streaming.

 

Is this a known problem - I don't see it referenced on a search here?  Media information attached.

 

Thanks!

As it's happening on two different players, you'll need to attach your server log. But how have you set up your library addresses? What path(s) are you using for your folders?

[Lonald 10]

Thanks, I have two Synology NAS devices.  The one being used for this movie is named in the library as \\Diskstation\Blu-Ray Movies\Rocketman (2019)

 

Server log is attached.

Does it always stop at the exact same spot?

[Lonald 10]

There are a couple of spots that I've noticed, though I haven't tried to go too deep.  One is early and during the credits and the other is at 3:19.

 

Thanks!

[Luke 40063]

And they are consistent?

[Lonald 10]

Yes, they are.

[Luke 40063]

And it's only this file? Is it an mkv?

[Lonald 10]

Hi,

 

Yes it is an MKV and this is the one file I've encountered this behavior with.  Does play fine with Kodi.

Would you mind trying it in mpv for windows and see how that compares?

You should be able to just drag the file onto the window. thanks.

[Lonald 10]

Hiya,

 

MPV plays the file without any problems - at least through the first couple of spots where there's been halts.

 

And just to check, the playback halts on Emby at 3:19, which is the usual spot.

 

Thanks!

Try disabling audio bitstreaming and hardware acceleration in theater.

Couldn't find the audio bitstreaming, but with hardware acceleration off the playback is working!

 

Thanks!

 

Is there any other information that would help?

[Lonald 10]

Spoke too soon.  The playback stopped at 5:32 into the movie.

 

Grrr....

[Guest asrequested]

Can you follow this and post the log, please?

Did you stop playback when it paused itself? Or did you resume?

[Guest asrequested]

I think the audio is the problem. You're using optical and it's trying to output 7.1. What do you have the audio channels set to in Theater? You should have that set to auto. And if using audio bitstreaming, only select AC3 and DTS. mpv will decode all other audio, but multichannel audio will be converted to stereo. Optical only supports stereo raw audio. There is a way to have mpv convert everything that's not supported to AC3, which will support up to 5.1.

Interesting.  I do have Theater set to "Auto" for the audio.

 

I enabled audio passthrough for DTS & AC3 and the recording stopped at the same spot.

 

I also tried switching the speaker layout to Stereo without improvement.

 

Thanks!

[Guest asrequested]

Something is wrong. mpv by default should downmix to stereo with 7.1 audio over optical. In a little while I'm going to have you replace mpv, and try again. I just need to get to my computer.

[Guest asrequested]

How do you have your windows audio, configured? It should be stereo.

[Lonald 10]

Just checked.  Windows is set up as stereo.

[Guest asrequested]

OK, I'm going to give you something that should 'workaround' the issue, and possibly give you something that you'll prefer.

 

First, your audio settings should look like this:

 

 

 

Then add this line as the first line of the mpv.conf that you made for logging.

af=lavcac3enc=yes:384:3

[Lonald 10]

Got it.  Now the movie plays, but no sound.
