Thread: Transcoding Resources

  1. #1

    Default Transcoding Resources

    Hi all, im using mezzmo on my pc streaming over a wired network (100mbit) to my 3dtv, which is working fine as far as the tv as dlna is concerned.
    the issue i have is when mezzmo needs to transcode it cant seem to do it quick enough.


    im running a i7-930 with 16 gigs of ram running of a ocz SSD, so would have thought that the power required to transcode on the fly is there.

    when i try to play a movie being transcoded i get the jittery,pausing problems and if i look at the transcoding status of mezzmo its sits around 20fps drops to as low as 10 (too slow error) im wondering what i can do if anything to smooth this out at all.

    im currently pre transcoding a movie and i suspect this will play fine, but will let you know shortly when it is finished.

    any help would be appreciated.

    Your computer spec and home network are fine. My guess is that ffmpeg.exe is just slow transcoding some of your files. Mezzmo uses ffmpeg.exe for transcoding video and music files and it can be quite slow to convert certain formats (whereas of other formats it is very fast). That could be the reason. Can you post the FFmpeg information on one of the (slow to transcode) files? Right-click on the file in Mezzmo and click 'Get FFmpeg Information'.

    We will be releasing a minor update in the next 1-2 weeks and that will contain the latest build of ffmpeg. This new build may help as the ffmpeg developers can often fix certain bottlenecks.

    OK - that's great that you can watch the video without stuttering via Mezzmo pre-transcoding features. I suggest we wait for the new Mezzmo update to see if that improves your transcoding speed. If not, then we'll look into it further for you.

    The 'Panasonic Viera' device profile may be a better match for your TV model - so that's great you are up and running now

    Please try this: Stop your Mezzmo server. Go to Media Devices dialog in Mezzmo and delete all devices listed. Start you Mezzmo server again and you should see your TV get added back into the Media Devices dialog again. Make sure it is using the Panasonic Viera device profile as before. Try streaming a few files and see how you go now.
