(that is only 1st pass, but similarly for the 2nd pass)
I tried that, and it is even worse.
Anyone knows better? I meand where in the script should I try to put
demuxer=lavf if at all?
But the problem seems to have gone away with the mencoder.
It seems to be mkvmerge program of the mkvtoolnix package problem.
That is, I *can* get good encodes with my script, that I posted in the
first post, but when I encode it to matroska, I get that the file is
not playable with the old versions posted in my first post.
I deduce that it is not a mencoder issue, because I can get playable
matroska reencodes from VIDEO_p2.avi (see the 1st post), if I encode
it with the old mkvmerge version of the program...
Just not to leave the thread incomplete, for posterity, if need be :-)
Cheers!
