Thread: Just about to buy mezzmo but I have encountered an audio problem

    Default Just about to buy mezzmo but I have encountered an audio problem

    Hi, I have been trialing Mezzmo and thought all was OK, until this evening.

    When Mezzmo started to play an avi movie file, it said the audio was not supported and so there was no sound. The same movie file plays OK with the sound, using VLC media player on my PC.

    All other files Mezzmo has trans-coded have been fine without any problems. The Device Profile I am using is Samsing B (MPEG-2).

    If Mezzmo cannot trans-code avi to MPEG-2 then this is a problem that will prevent purchase. How I do to fix this problem, please?

    Thanks, Chris

    Thanks, Chris. This file should play fine (i.e. the format & codecs are supported by Samsung B-series TVs). The problem will be that the audio channel is encoded in such a way that your TV's firmware cannot decode and play it. VLC can decode and play it since it has better format and codec support as compared to your TV's firmware.

    The best thing to do is to re-encode the video so that it fixes the audio channel. You can do this with a video converter tool or you can do it by pre-transcoding the file in Mezzmo. To pre-transcode using Mezzmo, right-click on the video in Mezzmo and click 'Pre-transcode Files'. Select your TV and then click 'Choose Formats'. On the Pre-transcoding Formats dialog, select the bolded format and select the 'Force full transcode of all channels' checkbox. Click OK. Select the 'Pre-transcode files even if they match the devices supported formats' checkbox. Click OK and wait until the file has been fully transcoded. Then try streaming the video again. More information about pre-transcoding can be found here - http://forum.conceiva.com/showthread...nscoding-Files
