[ANNOUNCE] N9/N950 TV out control application

[Ville Syrjälä]

I finally managed to make some progress on "porting"
maemo-tvout-control to harmattan.

Code is here:
https://gitorious.org/maemo-tvout-control/n9-tvout-control

What you'll find there is a a very simple QWidget based GUI,
and backend code utilizing XRandR.

The backend supports a few extra knobs, when compared with
fremantle. However, I was too lazy to write the extra GUI
code. So the current GUI offers the same controls that
maemo-tvout-control has.

The ultimate plan is to write a nice QML GUI for this stuff,
although I don't know when I'll have time to learn QML.

Another idea I have is to move the backend code to a separate
library. The same should be done for the fremantle Xv based
backend code. This would provide a unified TV out control API
for both platforms.

Hello,

last year I merged maemo-tvout-control with control panel settings plugin for
Nokia N900. Code is now in Community SSU on gitorious

https://gitorious.org/community-ssu/maemo-tvout-control

and is based on your orignal code
https://gitorious.org/maemo-tvout-control/maemo-tvout-control

I created new tvout status menu plugin, it is in that CSSU repository too.

It is possible to merge my changes on CSSU to your project? I think it is not
good idea to have 2 separated projects which has same code.

(I sent you mail before I forked your code, but you do not responce...)

Great. Multiple different GUIs was the reason I tried to keep the
backend code separate.

Yeah we could do some merging. But perhaps now would a good time to
move the backend code into a separate library. I'm not sure if the
harmattan and fremantle code can coexist nicely inside a single library,
or if that would cause problems with the packaging and whatnot. But at
least we could provide a library with the same name, and the same API,
for both platforms.

That version which is in CSSU working as:

* status menu plugin is loaded at startup and only this plugin have access to
tvout-ctl.c code. It monitor gconf tvout keys and when some is changed, it
call tvout-ctl function to change xv properties. (also monitor for xv changes
and change gconf keys)

* control panel plugin and desktop widget (and other plugins that can be
implemented) only changing gconf tvout keys, nothing more.


In tvout-ctl is minimum changes. There was only removed hardcoded function
update_ui and tvout_ui_set_* Instead that, tvout_ctl_init function get pointer
to function which is called.

So tvout-ctl.c should be same in fremantle and harmattan with my changes. I do
not know harmattan, but I think that haramttan does not use any Gtk, gconf
libraries, so desktop widget, control and status menu plugins are only for
fremantle. I think that the best will be to have one repository for tvout-ctl,
one for fremantle (here will be fremantle plugins) in CSSU project and one for
harmattan. What do you think?

Sounds good. We don't really need a harmattan specific GUI repo,
at least yet. The standalone Qt GUI should work in both fremantle
and harmattan if the tvout-ctl API is the same. Some clever way to
handle packaging may be needed if there are differences. Perhaps
keep the packaging stuff in separate branches and merge master to
them when the actual code changes.

I now merged both Xv and XRandR codes to libtvout-ctl [1].

I changed the license of this library to LGPL 2.1.

There's a configure option to select the backend at build time. The
debian packaging will build the Xv backend.

I'm not quite sure how I'll sort the issue on how to build for
harmattan. The same packaging otherwise works for both platforms,
so it would be nice to have some decent way to detect the platform
during the build and use that to select the backend. It would avoid
having to duplicate the packaging and maintaining multiple branches.

Run-time backend selection would be another option, but seems a little
pointless considering you have to build separate binary packages for
each platform anyway.

I updated both maemo-tvout-control and n9-tvout-control to use the
new library.

That's not available in harmattan. But anyway I realized I need to
change the build dependencies anyway, so I just removed the packaging
from the master branch and moved it to fremantle and harmattan branches
for each platform.

So configure script can check if maemo-version exist. If yes build system is
fremantle otherwise harmattan.

The backend supports a few extra knobs, when compared with
fremantle. However, I was too lazy to write the extra GUI
code. So the current GUI offers the same controls that
maemo-tvout-control has.

Is it possible to get rotational support in there? So that showing
Music has very wide black bars, but is at least the right way up?

Is there a binary package with everything nicely precompiled?

Thanks in advance,

Andrew

Nope. At the very least you'd need to modify the X driver, and doing
it optimally from performance POV would require even more changes.

Dunno. I'm too lazy to distribute binaries.

So xrandr on Harmattan is more like 'xonlyoner' ;-)

Unlike Fremantle, in Harmattan, screen rotation is implemented in the
toolkit level. (eg. MTF or Qt-Components).
As far as X is concerned, everything is in landscape.

Well, somewhat, but the r left is actually the rotate, not resize. Let
me explain. There was some problem with pvr memory management, so
resizing the X screen is disabled by default. IIRC we added some
xorg.conf option to allow it, but there's a good chance of making a
mess of things if you try it.

What you could do is start X with a larger screen size (eg. 854x854), and
then you could safely rotate the LCD output. TV output rotation isn't
really possible since VRFB (tile based hw rotation engine) isn't used. If
you attempt to use non-VRFB based rotation (aka. DMA rotation) on the TV
output, the display controller is likely to fail since the DMA can't keep
up with the display refresh due to the non-tiled memory layout. The
third way to rotate would be using the GPU, but no one ever bothered to
implement that in the X driver.

There are other things you can do with the current xrandr support.
For example you could use a bigger screen size, and pan the LCD and
TV output viewports to non-overlapping positions, which would give
you independent content on each output. There are going to be problems
with touch coordinates though, and the WM doesn't know how to the handle
the situation either. Also page flipping only works as long as the window
size equals the screen size.

So there is a fair bit of xrandr functionality in the driver, but it's
not utilized by the upper layers. The main reason for that was that the
UI designers wanted the transitions to be glitch free, and there just
wasn't enough time to make that happen with xrandr.
