Can't transcode any mkv files.

[rosenhauer]

When I try to transcode any mkv files I get the following (done it test transcoding)

Code: Select all

"C:\Program Files (x86)\Wild Media Server\wmsmpeg.exe" -i "\\DMRNAS\1tb\Media\Vi

Seems stream 0 codec frame rate differs from container frame rate: 50.00 (50/1)
-> 25.00 (25/1)

Press any key to continue . . .

It looks like an issue with the Audio Stream #0.1 but I can play the original file just fine in Windows Media Player/Classic Player and VLC.

Has anyone seen this before?

I 've seen this when I tried to encode to mp3 instead of ac3.

[mp2 @ 0x7bf740]encoding 6 channel(s) is not allowed in mp2

Thanks, I finally found the setting that I needed to change. In the Transcoder->Codes, Frame under audio I had the channels at 0 (I assume this means don't change). I changes it to 2 and it all works great.
