* @xvcontext: our instance's #GstXvContext
|
|
* @xwindow: the #GstXWindow we are rendering to
|
|
* @cur_image: a reference to the last #GstXvImage that was put to @xwindow. It
|
|
* is used when Expose events are received to redraw the latest video frame
|
|
* @event_thread: a thread listening for events on @xwindow and handling them
|
|
* @running: used to inform @event_thread if it should run/shutdown
|
|
* @fps_n: the framerate fraction numerator
|
|
* @fps_d: the framerate fraction denominator
|
|
* @x_lock: used to protect X calls as we are not using the XLib in threaded
|
|
* mode
|
|
* @flow_lock: used to protect data flow routines from external calls such as
|
|
* events from @event_thread or methods from the #GstVideoOverlay interface

* @pool_lock: used to protect the buffer pool
|
|
* @image_pool: a list of #GstXvImageBuffer that could be reused at next buffer
|
|
* allocation call
|
|
* @synchronous: used to store if XSynchronous should be used or not (for
|
|
* debugging purpose only)
|
|
* @keep_aspect: used to remember if reverse negotiation scaling should respect
|
|
* aspect ratio
|
|
* @handle_events: used to know if we should handle select XEvents or not
|
|
* @brightness: used to store the user settings for color balance brightness
|
|
* @contrast: used to store the user settings for color balance contrast
|
|
* @hue: used to store the user settings for color balance hue
|
|
* @saturation: used to store the user settings for color balance saturation
|
|
* @cb_changed: used to store if the color balance settings where changed
|
|
* @video_width: the width of incoming video frames in pixels
|
|
* @video_height: the height of incoming video frames in pixels
|
