Mezzmo Issue With Subtitles (always on)

[DMViolator]

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'.

Hi Paul

Thanks. Attaching FFmpgeg info below for one of the movies :

Well after a fair bit of trial, error and testing I have found something interesting. Bearing in mind this is now a clean reinstall of Mezzmo, recreated Playlists and once again turned off subtitles (apart from burned, I left those on this time). This test is repeatable.

If I fast-forward the movie at all from the beginning, it will display subtitles. If I do not fast-forward, it does not display subtitles.

Does Mezzmo pick up certain settings at a certain time from when the file is played? It's the only thing I can think of.

Thanks for the FFmpeg information. It shows that the video file has 1 video channel, 5 audio channels and 8 subtitle channels. As you say, the Mezzmo is streaming the video file directly to your Oppo. The fact that your Oppo is displaying subtitles means that it is reading them from your video file's embedded subtitle channels. So, your Oppo's firmware is reading and displaying the embedded subtitles from within the video file. If you don't want these embedded subtitle channels delivered, then you will have to pre-transcode the video to another format. See this FAQ to pre-transcode videos - http://forum.conceiva.com/showthread...nscoding-Files.

If you are still having problems, turn on logging (see http://forum.conceiva.com/showthread...nostic-logging) and restart your Mezzmo server. Stream the video to your Oppo and when subtitles are displayed, then stop your Mezzmo server and exit Mezzmo. Zip up all the logs and email them to us at support [at] conceiva [dot] com.

Can you please look at my post above regarding fast-forwarding the movie and let me know your thoughts. The Oppo does not display the subs if I do not fast-forward the movie.

Yes, I read your feedback. It's strange the Oppo does this. To confirm Mezzmo server is not at fault, please email us a set of logs to support [at] conceiva [dot] com. We'll need to two sets: when you play the movie normally and no subs are displayed, and when you play the movie with fast forwarding and subs are displayed. Once we get the logs, we will check both scenarios to confirm who is at fault - Mezzmo or your Oppo's firmware.

Hi Paul. Thanks, I will provide logs as soon as I stop the MezzmoMediaServer process eating up 500MB of memory which it's currently doing (and hanging in doing so). Reinstall number 8 on the way.....

Log Files sent Paul, would be interested to see what the findings are.

Thanks - we'll report back after we analyse the logs.
