Qtopia driver

SDL Development
1

Hi All,

I am trying to execute mplayer with SDL as video output. But mplayer
will crash when draw frame.
Here is my test result. Can anyone help me? Thanks in advance.---------------------------------------

  1. configure libSDL with “–enable-video-qtopia”
  2. export SDL_VIDEODRIVER=qtopia
  3. ./mplayer -vo sdl /test.mpg
  4. error message “QPaintDevice: Must construct a Qapplication before a
    QPaintDevice”
  5. program exit.

So that I add “SDL_InitQPEApp();” in mplayer. Then, the error message
changes to

“Warning: Qpainter::end Missing begin() or begin() failed”
“Warning: Qpainter::setPen: Will be reset by begin()”
“Warning: Qpainter::SetBrush: Will be reset by begin()”

Then, program crashed.

P.s this error message is output from QT library. I guess I need to
modify or add some code to make the paint device works normally.

Best regards,
Green

Hi All,

I’ve fixed this problem. Where I modified is at
./src/video/qtopia/SDL_QWin.cc.

I marked the line “my_painter->end();” as below;==================================================
void SDL_QWin::unlockScreen() {
if(my_locked > 0) {
my_locked–; // decrease lock refcount;
}
if(!my_locked && my_painter) {
fprintf( stderr, “++++++++++++++++++++++++++ end
QDirectPainter, mylocked = %d\n”, my_locked );
//my_painter->end();
delete my_painter;
my_painter = 0;
}
}

Best regards,
Green
