RTMP support

[Riccardo Arena]

Hi everybody,
i started today developing a QT4 application, using gstreamer as
backend for Phonon.
The application will play a rtmp stream from a red5 server.
I installed the rtmp plugin from the bad repository (gst-plugins-rtmp).
In qt, i created a simple Phonon::VideoPlayer, set it's source to
rtmp://localhost/oflaDemo/prometheus.mp4.

The VideoPlayer then starts playing only the audio channel. How can i
make it play the video too?

Thanks and sorry for the dumb question.

Hi,

just with the following tips you should get it working

#include <QtGui>

#include <QApplication>

#include <QCoreApplication>

int main(int argc, char *argv[])

{

    QApplication a(argc, argv);

    QCoreApplication::setAttribute(Qt::AA_NativeWindows,true);

.

.

.

and

QApplication::syncX();

gst_x_overlay_set_xwindow_id(GST_X_OVERLAY(sink), widget->winId());

and

gst_element_set_state(v_pipeline, GST_STATE_PLAYING);

Hi and thanks for the response.
Unfortunatly i still can't reproduce the video stream.
This is the code i use

Phonon::MediaSource * tst = new
Phonon::MediaSource("rtmp://localhost/oflaDemo/prometheus.mp4");
ui->videoPlayer->load(*tst);

 GstElement* sink;
    sink = gst_element_factory_make("xvimagesink", "sink");
    gst_element_set_state(sink, GST_STATE_READY);
    gst_x_overlay_set_xwindow_id(GST_X_OVERLAY(sink), ui->videoPlayer->winId());
    gst_element_set_state(sink, GST_STATE_PLAYING);
    ui->videoPlayer->play();

This is what i see when i put the window in background and get back in
foreground:

I'm on gentoo linux 3.3.8 with gstreamer-0.10,
phonon-gstreamer-4.6.2-r1, gst-plugins-rtmp-0.10.22

Thanks for the help.
