* @caps: the target format of the frame
*
* Action signal to retrieve the currently playing video frame in the format
* specified by @caps.
* If @caps is %NULL, no conversion will be performed and this function is
* equivalent to the #GstPlaySink::frame property.
*
* Returns: a #GstBuffer of the current video frame converted to #caps.
* The caps on the buffer will describe the final layout of the buffer data.
* %NULL is returned when no current buffer can be retrieved or when the
* conversion failed.
*
* Since: 0.10.30
