|

|
|
* The #autodeinterlace element is used to automatically select the right
|
|
* deinterlacer based on the caps of the stream. It can plug several elements
|
|
* to download/upload to/from the GPU when required/best.
|
|
*
|
|
* Note: This element guarantees that caps negotiation works but when setting
|
|
* properties that are not available on the best underlying deinterlacer some
|
|
* upload/download might be required and performance are impacted.
