Hi All, Due to a disk failure I've just rebuilt everything and have been playing with all the latest codecs out there. I've encoded some material I collected from DVB using transcode into MPEG-4 using XVid and Vorbis. There are two ways I can merge the audio and video files into one complete files: ogmmerge to produce an OGM and mkvmerge to produce an MKV. I notice that when I play the .MKV file back I have to give a -delay -0.3 to get the A/V correct. I do NOT need to do this with the .OGM file. Any idea what is going on here? MPlayer is using the same backends (xv and oss) for output and I can't see how the packaging should be affecting it. Any ideas?
