/**

|
|
* Reverse playback example.
|
||
|
|
*
|
||
|
|
* The Movie.speed() method allows to change the playback speed.
|
||
|
|
* Use negative values for backwards playback. Note that not all
|
||
|
|
* video formats support backwards playback. This depends on the
|
||
|
|
* underlying gstreamer plugins used by gsvideo. For example, the
|
||
|
|
* theora codec does support backward playback, but not so the H264
|
||
|
|
* codec, at least in its current version.
