[MEncoder-users] -vf bmovl and raw video output

[Ivaylo Mitov]

Hello guy,
when I do the following:

mencoder -vf format=i420,bmovl=0:0:/home/enctest/mylogo.fifo -nosound
-ovc raw -of rawvideo -o mp4-video.raw "$INPUT_VIDEO"

I get:

Try appending the scale filter to your filter list,
e.g. -vf spp,scale instead of -vf spp.

If I try without format=i420 - like this:

mencoder -vf bmovl=0:0:/home/enctest/mylogo.fifo -nosound -ovc raw -of
rawvideo -o mp4-video.raw "$INPUT_VIDEO"

the raw output is created but the colors are wrong and the video is all
blue.

With format=i420 and without bmovl the video encodes fine and the colors
are fine.

I also tried with format=yv12 - again blue video.

So my question is - is there a way do dump uncompressed video with
mencoder while applying a watermark with bmovl and keep the colors
correct?

Thanks in advance,
Ivo
