    Default Transcoding & TC-L58E60 (TC-LXXE60)

    I have a Panasonic TC-L58E60. Mezzmo saw this device as a Viera 2011 device. The screenshots show 2 different mkv files, one at 1280/720 AC3, and another at 1920/1080 DTS. Neither of these files need to be transcoded. The TV will play them as is.

    However, with the 2011 profile, Mezzmo attempts to transcode both files.

    I changed the device profile to Viera 2013. That changed it such that the 1920/1080 mkv file did not get transcoded. However, the 1280/720 AC3 mkv file does. Why? Is there more control over how/when transcoding works? I still have yet to look at the xml structure for the profile - maybe something there can be changed.

    Thanks

    Try the "Panasonic Viera (2011 models, DTS)" device profile and you may have more success.

    Thanks. That only partially works in that the DTS file doesn't get transcoded (which is the same as what the 2013 profile does). However, the 720p AC3 file still does and it doesn't need to. I'm wondering if there is a different way of controlling when/how transcoding works.

    Thanks

    Understand. Please post the FFmpeg information for the 720p AC3 file. Right-click on the video in Mezzmo and click 'Get FFmpeg Information'.

    Also, does this file play natively on your TV? To test this, right-click on the video in Mezzmo and click Properties. On the Properties dialog, go to the Transcoding tab and delete any transcoded files listed there. Then click the 'Use Original File' button and choose your Viera TV in the Choose Device dialog. This tells Mezzmo to stream the file natively without transcoding. Now stream the video on your TV. If it plays fine, let us know and we'll tweak the Panasonic Viera TV (2013 models) device profile accordingly.

    Thanks, Paul. Yes, I've been deleting the transcoded files. I've also used another media server to test. Thanks for pointing out those settings.

    So the setup now is to use the 2013 profile.

    MKV
    The 1080p file streams just fine.
    The 720p file will get transcoded, but it really doesn't need to. So to be sure, I set it up to 'Use Original File'. With that the file doesn't transcode (Don't see anything in the transcode status window and I check the directory to see if a file is created). Below is the FFmpeg information on that file.

    Got the updated profile - seems to work. I did a diff with the previous file and saw that level="51" was changed to level="41". I was wondering what this controlled?

    Thanks.

    Glad that works Thanks for confirming it.

    The level attribute in the device profile controls what H.264 profile level your device is able to decode and play. All devices can only play up to a certain H.264 profile level, and Mezzmo should transcode files beyond that profile level so they can be played on your device. 41 = level 4.1. 51 = level 5.1.
