Transcoding when muxing possible

Postby heddhunter » Thu Jun 04, 2009 7:12 am

I just discovered this piece of software today and I am very impressed.

One question though - how does it decide when to transcode and when to remux? I ask because I have files that I know are remuxable (mkv2vob says transcode not needed, and creates working files), yet PMS is transcoding the same files when I select them. Obviously I want to avoid transcoding whenever possible.

Post the MediaInfo (http://mediainfo.sourceforge.net) for the file and we'll tell you why... :)

Also check the preference of your transcoders ;)
If mencoder is the first one and not TsMuxer, then all MKV files will be trancoded by MEncoder instead of remuxing by tsMuxeR.
tsMuxeR is visible from #TRANSCODE# folder in this case 8-)

I have "Switch to tsMuxer when H264 video is ps3 compatible and there's no configured subs" checked. Does the presence of subtitles in the original count as "configured subs"?

Unless they are hardcoded into the video (meaning that you can't toggle them on and off when playing the file in player on the PC like VLC or MPC), then yes, they count as configured subs.

Also, I can't seem to view the MediaInfo image from your previous post with my work browser - post the text output.

I moved tsMuxer to be the top priority engine and now the files play without transcoding just peachy. I guess I can live with that - it's extremely rare that I would want transcoding on.
