Hi motoko,

Try this:



<avcontainer id="matroska" name="matroska,webm" encode="0" mimetype="video/x-matroska" preferredtranscoded="0" format="matroska" supportschunked="0" level="51">
<video>
<format id="mpeg4" encode="0">
</format>
</video>
<video>
<format id="h264" encode="0" videoprofile="100">
</format>
</video>
<video>
<format id="mpeg2video" encode="0">
</format>
</video>
<video>
<format id="vc1" encode="0">
<maxbitrate>15000000</maxbitrate>
</format>
</video>
<audio>
<format id="ac3" encode="0">
</format>
</audio>
<audio>
<format id="aac" encode="0">
</format>
</audio>
<audio>
<format id="mp3" encode="0">
</format>
</audio>
</avcontainer>


You will see that I have removed the "dca" section (which is ffmpeg's keyword for dts). This will tell Mezzmo server to remux/transcode your video files that have dts audio to mpegts (h264, ac3) so that your video will play on your LG TV. Let us know how you go.

Thanks for replying Paul, I tried what you suggested and the TV still didn't recognise the sound format. If it's any help, I only want the DTS audio transcoded as the tv can play h264 video perfectly. The normal LG profile tries to transcode the everything into a mpegts file, which is too much for my pc to handle. Also before all these updates it worked perfectly.

Hi motoko,

Please post the FFmpeg information for one of the video files that you are having troubles with. To do this, right-click on the file in Mezzmo and click 'Get FFmpeg Information'.
