Mezzmo Issue With Subtitles (always on)

**DMViolator** · 05-09-2013, 03:36 AM

Hi

Been using Mezzmo for a good while now with no issues, until yesterday.

I have Mezzmo 3.1.1.0 installed, streaming to an Oppo 93/Sony KDL-EX653. Basically the problem I have now is that whenever I stream a movie (BDMV container) that has subtitles in it, they are always displayed on-screen. I can only turn these off by selecting Subtitles on the Oppo (which shows off by default), selecting any subtitle track, then choosing off again. Then they disappear.

I have turned off every subtitle setting I can find in Mezzmo, and unticked the boxes in the file properties. Still the same.

If I hook up an external drive directly to the Oppo and play the same files, there's no subtitles displayed. And up until yesterday, there weren't any when I was streaming.

Not made any changes to Mezzmo that I'm aware of. Have uninstalled/reinstalled with same result.

*edit* I should mention that if I stream directly to the TV, there's no subtitles shown either.

Any help please?

Hi DMViolator,

Try this: Go to the Media Devices dialog in Mezzmo and edit your device. In the Device Settings dialog, go to the Subtitles tab and turn off the "Stream external subtitles", "Stream embedded subtitles" and "Burn subtitles" checkboxes. Next, go to the Transcoding tab and delete all your transcoded files. Click OK and restart your Mezzmo server. Try streaming now and see how you go.

Tip: We also have a subtitles FAQ that may provide more information if the above does not help - http://forum.conceiva.com/showthread...titling-Basics

Hi Paul

Thanks for the response. I have already tried that. Also turning off all subtitles in Global settings, going into file properties and unticking all subtitles and clearing transcoding cache. The Oppo doesn't and never has used transcoding in any case, as it handles all my media files natively.

It's best we see a set of logs and we'll see what Mezzmo is delivering to your device. Turn on logging (see http://forum.conceiva.com/showthread...nostic-logging) and restart your Mezzmo server. Stream a video to your device and when the subtitles appear, stop your Mezzmo server and exit Mezzmo. Zip up all the logs and email them to us at support [at] conceiva [dot] com.

Thanks Paul. I was in the process of doing this. Turned on Logging, stopped/started Mezzmo server etc. Played one of the films to test. And most bizzarely, no subtitles appeared!. Tried another 2 films that were showing before and they don't show either now.

Turned off logging, and even reset Oppo device back to defaults (as this is what it is usually on), and same result. No subtitles now.

I'd like to say there was some magic fix involved, but that's literally it

Interesting. The likely reason for this is that your Oppo device was caching its previous requests that it made to Mezzmo server. These requests would have had subtitle information in them and Mezzmo server responded accordingly (i.e. provided video with subtitles). Turning off/on your Oppo device or resetting it may have forced it to re-read the folder/playlist information from Mezzmo server (and this folder/playlist information would not have included subtitle information since you turned it off). Anyway, glad you are up and running. Thanks for posting your results for other Oppo owners to learn from.

And it's doing it again!. On version 3.2.0.0 now. Turned off all subtitle settings in Mezzmo general settings, and under each device. Stopped/restarted server. Rebooted. Reset Oppo. Still forces the subs!!!

If you have subtitles burnt into your transcoded files, then that would be the reason you still have subtitles displayed on your Oppo. Even though you have turned off subtitling features, Mezzmo is streaming the already transcoded file to your device and this transcoded file has subtitles burnt from previous streaming.

Go to the Media Devices dialog and edit your Oppo device. On the Device Settings dialog, go to the Transcoding tab and delete all transcoded files. Now try streaming. Let us know how you go.

Hi Paul

Thanks for the feedback. These files have played before no problem with no subtitles displayed and they are not burnt or transcoded in any way. The oppo is playing them direct.

Understand. My guess is that the subtitles are embedded into the video as a subtitle channel. Mezzmo is streaming the video directly without transcoding as you say, and your Oppo is probably finding the subtitle channel within the video and displaying it automatically. To confirm this, please post the FFmpeg information for one of the videos that has this problem. Right-click on the video in Mezzmo and click 'Get FFmpeg Information'.
