Loads a video from the specified file and predispose it for use with tempo, playback rate and pitch change. Depending upon the codec and the duration of the video clip to load, due to the fact that the loading is performed inside the main application's thread, the call to this method could cause a temporary freeze of the container application user interface: in order to avoid this issue, the use of the VideoPlayer.LoadSyncForTempoChange method should be preferred.
Video loading and rendering is performed through DirectShow so, in order to load a certain video format (like MPEG, MP4, AVI, etc.) the specific codec must be available on the target system or calls to this method would fail. One of the best packages containing most audio and video codecs for DirectShow is K-Lite Codec Pack and can be downloaded for free from the following link.
NOTE ABOUT TEMPO AND PLAYBACK RATE CHANGE: It's important to note that not all of the video codecs are able to manage playback rate change correctly: for example certain kind of AVI codecs will loose synchronism between audio and video when calling the SetTempoPerc or the SetRatePerc methods: this is not a limitation of our control but a defect of the codec when running the video at a speed different than normal. Furthermore, other video codecs are not fast enough in order to provide enough PCM sound data for tempo and/or playback rate change so you could experience "stuttering" during playback: when dealing with codecs that cause stuttering during playback it would be a better solution using the VideoPlayer.Load method.
A successful call to this method will fire the SoundLoaded event.
