Invalid image format error

[ramtheconqueror]

I'm using GStreamer (camerabin) to generate the jpg files which does work as expected on Linux dev machine and on Windows desktop. But my Qt application throws this error

QML Image: Invalid image data: file:///home/camera/capture_0.png

I'm using camerabin of GStreamer and using this image-capture-caps.

GstCaps *caps = gst_caps_new_full (gst_structure_new ("video/x-raw",
    "format", G_TYPE_STRING, "YUY2", "width", G_TYPE_INT, 1280, "height", G_TYPE_INT, 1024, NULL), NULL);
g_object_set (m_cameraBin, "image-capture-caps", caps, NULL);
gst_caps_unref (caps);
m_cameraBin->setProperty("location", "/home/camera/capture_%d.jpg");

I then call QGlib::emit<void>(m_cameraBin, "start-capture");

I've tried different formats like RGB which didn't work either.

Any help? Thanks

video/x-raw is raw video, QImage (and your code) assumes a image
format. Try using "image/png" to get a PNG image.
