Sample code for using MPS SDK for Python to add a start or end part to a video - ApsaraVideo Media Processing

Video merging allows you to merge videos of different formats, bitrates, and resolutions into a longer video of a specific format, bitrate, and resolution. It is usually used to add a start or end part to a video, or to merge the clips of recorded live streams. Video clipping allows you to capture a clip from an original video, and save the clip as a new video. It is usually used to capture highlights from videos. This topic provides an example on how to use the API operations that are encapsulated in ApsaraVideo Media Processing (MPS) SDK for Python to merge and clip media files.
