Hi all, I was trying to set up a pipeline to view the video stream coming from my webcam (sonix based), using a V4L(1) driver. The pipeline I'm trying to use is v4lsrc -> ffmpegcolorspace -> ximagesink Setting this up in gst-editor gives me a dialog telling me that it could not set a parameter, but after dismissing this I can see the webcam video stream in a window. If I try this using gst-launch gst-launch v4lsrc ! ffmpegcolorspace ! ximagesink it gives me a similar message (from the v4lsrc module). Apparently it tries to set the framerate and is unsuccessful doing that. (It tries to set it at 1 fps and at 30 fps). What does this warning/error mean? I thought v4l does not have any property to set the framerate. I tried various combinations of setting properties sync-mode and autoprobe-fps, but without success. Another, more general thing I wonder about: Is it possible to have controls for v4l? For example, being able to control brightness, contrast, whiteness, color and hue.
