[MEncoder-users] WMV3 Encoding Issue

[Denis Ogun]

Hi,

I am trying to encode this file:
http://www.megaupload.com/?d=C6N7PS7H

with these parameters:

mencoder C:\lotp.wmv -of lavf -oac faac -faacopts br=256 -ovc x264
-x264encopts
subq=5:frameref=5:bitrate=1600:me=umh:partitions=all:bframes=1:me_range=16:cabac:weightb:deblock
-fps 30 -vf scale=1280:720 -o C:\lotp.mp4

When I try to encode the video, it shows a huge file size of over double the
original. When I try to play it in mplayer I get these errors relating to
the faad decoder:

FAAD: Failed to decode frame: Unable to find ADTS syncword
FAAD: error: Unable to find ADTS syncword, trying to resync!
FAAD: error: Channel coupling not yet implemented, trying to resync!
FAAD: error: Gain control not yet implemented, trying to resync!
FAAD: error: Maximum number of scalefactor bands exceeded, trying to resync!
FAAD: error: Unable to find ADTS syncword, trying to resync!
FAAD: error: Pulse coding not allowed in short blocks, trying to resync!

Here is information about the video:
