Thanks, Paul!!

I've noticed this issue again with the TC-L58E60. It will transcode mkv files, when in fact it doesn't need to. The TV can handle it fine. So what I've done for now is to "Turn off transcoding for all connected devices".

What is the proper profile for this Viera. I see 2 profiles Panasonic Viera (2013 Base Models), which is what it defaulted to. And then there is Panasonic Viera (2013 Models). What's the difference? In either case, it will transcode mkv files that don't necessarily need to be transcoded.

Please post the FFmpeg information for the MKV that your Viera model can play (but Mezzmo transcodes). Right-click on the MKV and click 'Get FFmpeg Information'.

Here you go. Thanks for your help.

Another video that it will transcode, but doesn't need to:

The 'Panasonic Viera (2013 models)' device profile should not transcode either of these MKV files. One reason the MKV may be transcoding is to burn subtitles into the video.
The 'Panasonic Viera (2013 Base models)' device profile is designed for lesser featured Viera TVs (Panasonic change their DLNA streaming file format support depending which model you have from that particular series). It will transcode both these MKV files.

So, given you can play these MKV files without transcoding, then you should be using the 'Panasonic Viera (2013 models)' device profile.

The subtitles are embedded for the 3+hour video.

In the attached screenshot, I unchecked all 3 options, and tried again. It still transcodes the video as shown in the second screenshot.

Any ideas on this? For now, I will go with having transcoding turned off. For those that need transcoding, which should be seldom, I'll just pre-transcode it ahead of time.

Thanks.

Sorry for the delay in getting back to you. It's still strange that these MKV files are transcoding. One possible reason: Edit your Viera TV on the Media Devices dialog and go to the Advanced tab on the Device Settings dialog. Click the Default Settings button and save your changes. Try streaming your MKVs now. If they still transcode, then stop your Mezzmo server. Turn logging on (see http://forum.conceiva.com/showthread...nostic-logging) and start your Mezzmo server. Stream the MKV again and when it starts transcoding, stop your Mezzmo server and exit Mezzmo. Zip up all the logs and email them to us at support [at] conceiva [dot] com.
