    Hi!

    I would like to play movie files on my rpi 3 with framebuffer. From console is working fine:

    SDL_VIDEODRIVER=fbcon SDL_FBDEV=/dev/fb1 mplayer -vo sdl -vf scale -xy 320 /var/spool/samba/movies.....
    

    I tried lot of examples, but not working, what is the correct argument list to QProcess in this environment?
    It is a minimal sample:

            QString cmd;
    	
    	player = new QWidget();
    	pproc = new QProcess();
    	
    	player->setGeometry(0, 0, 320, 240);
    	
    	cmd = QString("mplayer -slave -wid %1 /var/spool/samba/movies...").arg(player->winId());
    	
    	qDebug() << cmd;
    	player->show();
    	pproc->start(cmd);
    

    Thanks a lot.

      Hi,

      It's the same as described in QProcess's details.

        Sorry, you misunderstood me, I tried also with QStringList type arguments.
        I need the mplayer's correct arguments.

          Did you check the outputs of QProcess to see if the application is starting properly and is doing something ?

            @SGaist

            I found the solution in the mplayer's docs, the -wid not working in linuxfb environment. The qprocess started the mplayer who writes the framebuffer directly, it's working.
