piping netcat to mplayer

Omri

hello!
When I write this line of code in the cmd:
nc ip 5000 | mplayer -fps 60 -cache 1024 -
I get a stream video running in mplayer from my raspberry pi server.
I want to do the same from a Qt app.
this is what i wrote but doesn't work:

QProcess *process1;
QProcess *process2;

process1 = new QProcess(0);
process2 = new QProcess(0);

process1->setStandardOutputProcess(process2);

QStringList args1;
QStringList args2;

args1 += "89.139.168.89 5001";
args2 += "-fps 60 -cache 1024 -";

process1->start("C:\\Program Files (x86)\\MPlayer for Windows\\nc.exe",args1);
process2->start("C:\\Program Files (x86)\\MPlayer for Windows\\mplayer.exe",args2);

what is wrong here?
thanks.

Hi,

Do you mean you have nc ip 5000 | mplayer -fps 60 -cache 1024 - running in a cmd.exe console ?

hello,
yes in the cmd.exe console.
actually now it works but with a strange bug. when starting the processes nothing happens, and after I close the Qt app(The UI window) the Mplayer jumps to the screen and the stream is visible. How can I make it jump during the time the app is running?
Another thing is I want it to appear in the app itself(Qwidget or Qmedia player). I did this to run a video from a file in the disk:
args2 += "-slave";
args2 += "-wid";
args2 += QString::number((int)ui->Mwidget->winId());
args2 += "C:\Program Files (x86)\MPlayer for Windows\MVI_1343.avi";

process2->start("C:\Program Files (x86)\MPlayer for Windows\mplayer.exe",args2);

and it ran inside the Qwidget in my app, though combining all arguments together doesn't work(I can't see the video stream in the Qwidget window).
thanks.
