[MEncoder-users] bmol overlay/watermark

[Matthew Augier (dps)]

Hi all

 

I'm working on a project in php that has to convert input videos to
FVL/WMP/MP4 to a specified size. This is my first encounter with mencoder,
but by using google and various websites I seem to pretty much have this
working.. Except the watermark I need to add!

 

Eg. my FLV

The mylogo.fifo was created using the convert command (gif with
transparency) followed by the echo cat stuff, and I believe it's ok.

 

The output plays perfect, but no overlay/watermark.. Is the "VDecoder init
failed :(" anything to do with the watermark, does that mean I created it
wrong?

 

Any help/pointers welcome!
