auto crop would help using the full screen width

[GoogleCodeExporter]

feature request (no bug):

What steps will reproduce the problem?
1. choose a file with black borders at top&bottom (e. g.: a cinema movie
broadcasted in 4:3 TV format)
2.

What is the expected output? What do you see instead?
(a) i would like to have a window that shows only the interesting part of
the movie...
(b) a big part of a wide screen will be unused (even in full-screen-mode).

Do you do this with command line mplayer? If so what commands on the command 
line do
you use? Several of the ones I have tried either do nothing or fail.

hm

i wouldnt do it via mplayer's options, because we had to restart mplayer 
whenever the
aspect ratio changes... right?

my idea was this:
we change the visible rectangle
(e. g. we tell mplayer that the video should have 1440x1080, but we just show
1440x900+0+90 of that inside the gnome-mplayer window)...
(something like that happens when the size of the gnome-mplayer window changed?)

workaround:
currently i do it by moving the window partially out of the screen and then i 
enlarge
its height until the movie fills the full width,
which takes some time...
but the workaround is ok, i just thought there would be an easier automatism... 
:-)

There is experimental support for this in SVN. Do make this work you have to run
configure with --enable-panscan and use a very recent SVN version of mplayer. 
The
reason for the compile flag is that old mplayer's will break and show 
incorrectly.

i took today's SVN snapshots... but: the aspect of the movie didnt work and i 
was
unable to find any "panscan" related option... did i install it the wrong way?

There are no menu options just the W/E keys control it. Also I'm not sure what 
you
are seeing but when you say "didn't work" almost always will be 1 of 2 problems.

1. For gnome-mplayer, run make clean, use the "--enable-panscan" option when 
running
configure

2. Your mplayer is to old, I tested with MPlayer SVN-r29629 and it works 
correctly

1.
that is what config.log says:
$ ./configure --enable-panscan

2.
hm
i used _today's_ svn version from here:
http://www.mplayerhq.hu/MPlayer/releases/mplayer-checkout-snapshot.tar.bz2
(it has the same ChangeLog file like r29629 (i downloaded that one, 2, 
now...)...

(a)
when i try to change the aspect ratio (with the "a" key), i get this with option
"--reallyverbose":
thread reader: VDec: vo config request - 720 x 576 (preferred colorspace: 
Unknown 0x0000)
thread reader: VDec: using Planar YV12 as output csp (no 0)

Resizing to 1024 x 576
current size = 720 x 578 
new_width 720 new_height 400

(b)
with "o" + "eeeee" i get a bar, but the black areas at the top and bottom dont 
change...

(c)
then i found that i cant c the mouse cursor, when i move it into the movie 
window area...

oh - i should add to (a),
that the picture doesnt change, when i change the aspect... it just flashes 
green for
a short moment and then everything looks as before...

ok, please follow this...

Open a video, make the window taller than it is by default (say at least 1.5 to 
two
time, and do not make it wider)... leave all the options alone, press the e key
several times, you should see the video zoom in.

The aspect key should have little to nothing to do with this feature.

Original comment by kdeko...@gmail.com on 2 Sep 2009 at 2:52

[GoogleCodeExporter]

i made it taller and the whole window was filled with the video, because the 
aspect
ratio changed... somehow it is always in "Follow Window" mode, although i didnt 
want
it...

btw: did u mean "wider"?
when i make it taller the upper/lower black areas just get bigger...
but i want them to get smaller, when the movie can get wider, because the 
window is
wider than the movie can use it...

[GoogleCodeExporter]

When the window is doing "follow window" mode, I believe it is due to an old 
mplayer,
this is why I have the configure flag. I know you say you have installed the 
latest,
however it is not acting like it so I need you to please post the gnome-mplayer 
-v.

Ok, back to your previous comment

> when i make it taller the upper/lower black areas just get bigger... 

This is what it is supposed to do. Then as you press e these areas should get 
smaller
as you "zoom" into the video.

I also added an extra debug flag to SVN that shows if the app is running in 
panscan mode

Original comment by kdeko...@gmail.com on 2 Sep 2009 at 4:12

[GoogleCodeExporter]

Also, you can make it wider too. The w key unzooms the picture and the e key 
zooms
the picture to fill the black area, chopping of the edges to do that.

Original comment by kdeko...@gmail.com on 2 Sep 2009 at 4:14

[GoogleCodeExporter]

Ah! I see the problem... apparently the --enable-panscan option is not being 
enabled
during configure

I can tell this from your mplayer commandline

/opt/home/aw-loud/install/mplayer/mplayer-checkout-2009-09-02/mplayer -profile
gnome-mplayer -quiet -slave -identify -volume 100 -framedrop -vf-pre
yadif,softskip,scale -noconsolecontrols -noidle -stop-xscreensaver -osdlevel 0
-nomouseinput -cache 9680 -wid 0x4800056 -ss 0 -ass -noembeddedfonts 
-ass-force-style
FontName=Sans,Italic=0,Bold=0,Outline=0,Shadow=0 -ass-font-scale 1.00 -ass-color

export=/tmp/mplayer-af_exportfsmkot:512
/opt/home/aw-loud/deploy/mm/tv/cache/PB/s4/e21.mpg 

When panscan is properly enabled there should be a -fs after the -wid 0x4800056 
option.

So do this in the gnome-mplayer source

make distclean
./configure --enable-panscan
make

then retest. I think this should fix your issue.

Original comment by kdeko...@gmail.com on 2 Sep 2009 at 4:31

[GoogleCodeExporter]

i did that "make distclean ; ./configure --enable-panscan ; make" trick, but i 
still
had that problem...

i added "-fs" to "~/.mplayer/config", which worked fine...

then i did a "svn update" of "gnome-mplayer" and just typed "make", which 
solved the
problem: everything is fine now... w00t! :-)

but the steps r too big for my taste... how can i get smaller steps?

Original comment by goo...@wgboome.org on 2 Sep 2009 at 5:30

[GoogleCodeExporter]

the steps are set in gui.c around line 1877. change the 0.1 to smaller values 
like 0.05.
