How do you mean?
Where do I put it in my script?
I looked it up a little (trying to figure it up, I mean trying to
understand better all of it in the docs...),
but if you know where it fits, can you tell me?
I'll try and guess. Is it this line to add:
demuxer=lavf
say between these two lines in both the scripts for 1st and 2nd pass
from my first post:
ovc=x264=1
x264encopts=pass=1:slow_firstpass:bitrate=900:bframes=1:trellis=1:qp_step=4:qcomp=0.7:direct_pred=auto:keyint=125
and making them:
ovc=x264=1
demuxer=lavf
x264encopts=pass=1:slow_firstpass:bitrate=900:bframes=1:trellis=1:qp_step=4:qcomp=0.7:direct_pred=auto:keyint=125
(that is only 1st pass, but similarly for the 2nd pass)

Yes, but it worked before, as I explained in the previous post.
Thanks!
