[MEncoder-users] Mencoder vdpau usage possible ?

[belcampo]

Hi,

Not looking for speed improvement.
When encoding a short BBC-HD clip with ffmpeg I get annoying blockiness 
in the first few frames, I issued the problem on the ffmpeg round-up, 
the reference decoder didn't show that problem.
When playing the same clip with mplayer's default ffh264 I do see the 
same blockiness.

However if I use -vc ffh264vdpau it's perfect.

So my thoughts are that encoding with mencoder -vc h264vdpau would solve 
my blockiness problem. But I can't get a decent command-line to do this.

I tried:
mencoder source.ts -o destination.avi -demuxer mpegts -vc ffh264vdpau 
-vf scale=720:576:0 -nosound -ovc x264 -x264encopts .....

The output I get is:

Try appending the scale filter to your filter list,

I tried to change:
-vf scale=720:576:0
to
-vf spp=0:0:0,scale=720:576:0
Then I get:

Could someone help me with this matter, would be very pleased.
