[directfb-users] Re: [MPlayer-dev-eng] matrox 550 tv out andmplayer problem



I get the same output if I eliminate the -aspect option.

But what I don't understand it why it's trying to scale at all. This
is the information that the demuxer generates (I think):

==> Found video stream: 0
MPEG-PS file format detected.
==> Found subtitle: 0
==> Found audio stream: 128
Searching for sequence header... OK!
VIDEO:  MPEG2  720x480  (aspect 2)  29.97 fps  9800.0 kbps (1225.0 kbyte/s)

If the video on disk is 720x480 and my screen is 720x480, why is it
up-scaling
to 720x540?

What do you see without any options?

This is mplayer's prescaling code. It always wants to upscale instead of
downscale and it doesn't know that our screen size is limited to 720x480.
Something in the rest of the aspect code doesn't like this and you end up
with a black screen. -xy 720 should fix this if the prescaling code makes
the width too big but I'm not sure there's any way to fix it if the height
is too big.
