Examples of com.xuggle.xuggler.IContainer.open()

com.xuggle.xuggler.IContainer.open()
Open this container and make it ready for reading or writing. Reading or writing ability is determined by what the {@link com.xuggle.xuggler.io.IURLProtocolHandler}passed in supports. @see #open(String,IContainer.Type,IContainerFormat)

    IContainerFormat format = IContainerFormat.make();
    if (format.setInputFormat(driverName) < 0)
      throw new IllegalArgumentException("couldn't open webcam device: " + driverName);
    
    // Open up the container
    int retval = container.open(deviceName, IContainer.Type.READ, format);
    if (retval < 0)
    {
      // This little trick converts the non friendly integer return value into
      // a slightly more friendly object to get a human-readable error name
      IError error = IError.make(retval);
