    Default Playback MOV from Canon EOS 7D on Samsung

    Context : Canon EOS 7D, Samsung TV UE37C6820, Windows 7 (64bit), Mezzmo V2.1.9.0
    Mezzmo works fine i.e. I can browse photos from/on the PC and display them on the TV, idem for video and audio.

    Behaviour : The MOV files recorded with the Canon are copied on the PC's Harddisk. They can be perfectly watched with Quicktime on the PC.
    When I playback a MOV file on the TV, it plays for 2-3 sec. and then switches to the next one, it plays again 2 sec. The 3rd MOV file (sometimes the 2nd) makes the TV reboot i.e. TV switches off and on again!
    MOV files (not recorded with Canon) play well.
    When I browse the PC's folder containing those MOV files, the thumbnails appear correctly.
    Playback of a MOV file takes 2 minutes or more to start.
    MOV file size = 200-500KB

    Question : Does somebody have a similar experience?
    Does anybody have a solution so that "I can see my kids play" on my TV screen in HD?

    Can you please FFmpeg information about one of those MOV files (in Mezzmo right-click on the file and use the "Get FFmpeg Information" command)?

    Here is the FFmpeg info you asked for.
    One thing to mention also, the TV has a wired connection to the LAN via a D-Link router/switch.

    45 Mbits, 1920x1088 is probably using High Profile @ Level 5.1, which is rarely supported by TVs (as this is BlueRay quality). Usually, Level 3.1 or 4.1 is the highest that can be played through DLNA, at a few Mbits (check your TV specifications for details).

    You can confirm the file profile by using Mediainfo: http://mediainfo.sourceforge.net/en

    I can see the Format profile is Baseline@L5.0.
    This is info I found in TV's manual :
    Samsung_Decoder_specs.jpg

    Does this mean I cannot play these MOV files on a Samsung UE37C6820 at all?

    The only way would be through transcoding. Unfortunately, Mezzmo is currently unable to determine the H264 profile and level used by a file, so it can't tell if a given H264 file needs transcoding or not. Conceiva is aware of the issue and are actively working on a solution.

    One possible workaround would be to modify your device profile to force transcoding any H264 file that has a video size larger than 1,280×720 (since Level 5.0 only supports 1920x1080 or higher, it means that you would be transcoding anything susceptible of being Level 5.0 or higher). This is something Conceiva can help you with after the weekend if you aren't comfortable with editing device profiles Send them an email about this at support (at) conceiva (dot) com mentioning this, and they should be able to send you back an updated profile for you to try.

    For reference, the resolutions supported by various profiles can be seen on Wikipedia, under "Levels": http://en.wikipedia.org/wiki/H.264/MPEG-4_AVC

    Mezzmo 2.1.10 will be profile-aware (already implemented and being tested right now), so hopefully that'll solve these issues
