[MPlayer-dev-eng] writing video output plugin

[Vrihad Shoonya]

Hi!

SiS hw mpeg driver decodes pictures directly to video
buffers. I think this would not allow me to run an mpeg
video in a window in X; i.e. allow X output. Am I correct?
Does this mean I have to use "EXPORT" in imgtype(mp_image.h)?
Also is it feasible use "TEMP" and copy data from video buffer
to mplayer supplied buffer so that I can get an X output?
In that case I am worrid about the performance. The CPU in
question is a 200MHz. x86 compatible.

I am doing something similar. I feed the driver with encoded
data along with some custom headers containing relevant data
for decoding.

Thanks in advance
