[MEncoder-users] Option x264encopts: Bad argument b_pyramid=(null)?

[Simon]

Hi There,

We are using mencoder as part of a scipt to transcode a mp4 to a m4v file.
This is running the latest version of mencoder compiled this morning on
Debian Testing.

This is the command we are using:

mencoder "$1" -o "$outdir/${iFile%%.*}_temp.264" \
-passlogfile "$outdir/${iFile%%.*}"_temp.log $rsize -ovc x264 -x264encopts \
bitrate=$itemVideoBitrate:frameref=4:bframes=3:b_adapt:b_pyramid:weight_b:partitions=all:8x8dct:me=umh:subq=7:trellis=2:threads=auto:pass=1:analyse=all
-of rawvideo -nosound

When we run this... we get this output:

MKMP4 : Triggering the encoder with source media: preview.mp4.
MKMP4 : Encoding: preview.mp4
MKMP4 : Resizing to: Movie is not being resized..
MKMP4 : Total Bitrate: 512 kbps.
MKMP4 : Video Bitrate: 464 kbps.

Any ideas on this one? We have complied and installed x264 before compiling
mplayer...

Thanks
