MEncoder Muxing Problems

MuLTiTaSK · Post by **MuLTiTaSK** » Sat Jun 23, 2007 9:20 am

whenever i enable the muxer to use mencoder to mux the encoded avi file the output doesnt come out as a OpenDML avi even though i have Do not write OpenDML index for avi files set to false

plus the muxed file has 4 consecutive B-VOPs but i set the max to 2 in the xvid options

if i disable the muxer the encoded files come out the way i want is there a reason for this?

here are the command line options used with muxer enabled

can anybody confirm if there having the same problem as me please?

B!ink · Post by **B!ink** » Tue Jun 26, 2007 8:26 am

I have no explanation for that. I always set the muxer to disable.

i have the muxer set to disable aswell the encodes come out fine without it hopefully stan da man can explain why this happens
