LVC video output
The LVCVideoOutput class is used to add video outputs to the LVC pipeline. You can start and stop the output pipeline independently from the main pipeline.
Usage
When creating an LVCVideoOutput object, you must specify the MediaBlock to be used as the video data output. Usually, this element is used to save the video as a file or stream it (without audio).
For video+audio outputs, use the LVCVideoAudioOutput class.
You can use the SuperMediaBlock to make a custom block pipeline for video output. For example, you can add a video encoder, a muxer, and a file writer to save the video to a file.
