    Default Some mkv files play video and some others don't

    Hi there,

    I am having problems when streaming mkv files to my media player. Some mkv files play normally (no transcoding done) and some play sound but no video. I guess those that won't play are not supported by my media player and due to the device profile selected no transcoding happens. I am using a "bright-view cinematube" device profile, as proposed by Mezzmo when connecting, because my media player (OKI Soundbar 1G) is not supported. This is the FFmpeg information for two examples:

    This first file doesn't play video (audio OK):

    This second one, plays fine, both video and audio:

    Is there anyway I can fix this using a specific device profile, forcing transcoding for that particular file or so?

    Thanks a lot.
    Antonio.

    Can you please send us a message to support (at) conceiva (dot) com and we'll send you another device profile to try (it's not part of the currently released Mezzmo yet). We can also make a new device profile for your unit - to do that we need some logs, so can you please turn on logging (see this thread: http://forum.conceiva.com/showthread...nostic-logging) then browse Mezzmo using your device and try to play one file. After that stop the server and send in the logs as well.
