Opus multichannel audio still doesn't work on Roku

I won’t belabor the issue as it has already been addressed in at least 2 closed threads.

Plex for Roku Opus audio sounds choppy/warbly

Server Version#: 1.18.3.2111 Player Version#: 6.4.8.6145-8164e1910 74529.txt (2.9 KB) This 602kbit HEVC/80kbit Opus file I created from a DVD I had laying around (remuxed and used h265ize with --he-audio --normalize-level 4), along with many others I have floating around using Opus, the audio sounds choppy and unlistenable on Roku Streaming Stick+ (3810rw) when direct playing. Works fine on PC direct play as well as android direct play. Unfortunately I have a lot of things I’ve encoded with…

Plex for Roku Opus audio sounds choppy/warbly

Server Version#: 1.20.1.3252 Player Version#: Roku Ultra Player 6.6 Build 8 I have video in HEVC that has OPUS 5.1 audio that the Roku client attempts to direct play which results in choppy weird audio. If I disable direct stream the issue is resolved once the audio is transcoded. Any tips to fix this without having to disable direct play every time for this content?

Basically it sounds horrible with direct play. If it is forced to transcode, which is obviously not ideal for the video, then PMS transcodes the audio to AC3 which plays fine.

Whether the implementation of opus support is broken or if Roku just can’t handle it, I don’t know. It would be nice if at least for Roku PMS would transcode the audio if Roku can’t handle it natively. If the Roku can handle opus, like my Fire stick can, then it would be nice to be able to actually direct play it. But one of those two things should really happen. Having to manually change the device settings just for those files is not ideal. Reencoding and remuxing is not really a fair suggestion either.

Bump…

@ljunkie - sorry to tag but odd that 3 threads on this and no apparent feedback. Would be fine with me to just make PMS transcode opus for Roku. At least it would be functional.

I can upload a file to the cloud for testing if need be. Or should I just starting tagging a bunch of people?

[ljunkie]

A sample file is always best so we can reproduce in house and isolate the issue.

[SkylerWolfe]

Sure. Here is one. Again, I think it would be fine to even just have PMS handle these files my transcoding audio for Roku but just leave the video alone.

If you were able to download that file, let me know and I will remove it from my cloud storage.

[SkylerWolfe]

Was anyone able to recreate the issue?

[ljunkie]

Yes. We have been able to replicate the issue. We’ll update this thread when we have a solution. Thanks for the report and sample.

[ljunkie]

From what we can tell this only affects OPUS having more than 2 channels. I think we’ll limit the workaround to OPUS having more than 2 channels. Do you have any stereo OPUS streams that replicate this behavior?

[SkylerWolfe]

I don’t have anything that is opus stereo, but it would be easy to use handbrake to reencode it and down mix the 5.1 file to stereo opus. I can do that and upload it to dropbox if you would like.

[ljunkie]

We have already tested opus stereo and it seems to work just fine over here. I just wanted to check in to see if you could verify. No worries! thanks.

[SkylerWolfe]

I tested it anyways and, yes, it did work once down mixed to stereo opus as you said.

[SkylerWolfe]

Sounds like it has been fixed in 6.7.18. I’m out of town so I can’t test till the weekend. Edit - fixed.
