You can also combine detection algorithms or create new ones from scratch.įor a more advanced example of using the PySceneDetect API to with a stats file (to save per-frame metrics to disk and/or speed up multiple passes of the same video), take a look at the example in the SceneManager reference.

Using a SceneManager directly allows tweaking the Parameters passed to detect_scenes including setting a limit to the number of frames to process, which is useful for live streams/camera devices. detect_scenes ( video ) # `get_scene_list` returns a list of start/end timecode pairs # for each scene that was found. add_detector ( ContentDetector ( threshold = threshold )) # Detect all scenes in video from current position to end.

$ ffmpeg -i muxed.mp4 -c:v copy -map 0:0 video.m4v -c:a copy -map 0:1 audio1.m4a -c:a copy -map 0:2 audio2.m4a -c:s copy -map 0:3 subtitle1.srt -c:s copy -map 0:4 subtitle2.srt After that, use the -map : option to address individual streams. To find out which stream has which index. In this example it is assumed you want to demultiplex the video file muxed.mp4 that contains a video stream, two audio streams and two subtitles which you want to store in separate files. To extract a certain stream from a file, you also use the -c copy and additionally the -map : option for file and stream selection. Here is the command that does it for you: In this example it is assumed you have a large video file called longmovie.mp4 which you want to split in segments from the beginning to 0:05:00, from 1:00:00 to 1:05:00 and from 1:30:00 to the end with all streams passed through.

Use the -c copy option to make sure that all streams from the original files will be passed through to the segments. If no start position is given, the segment will start at the beginning of the original file, if no length option is given, the segment will end at the end of the original file. Timecodes are of the form hh:mm:ss.ms, i.e. You can tell ffmpeg the start position of a segment with the -ss option and the length of a segment with the -t option.

What you need are the start timecodes and the length of the segments you want to cut. If you have a large video or audio file and want to split it into several smaller files, you can use ffmpeg to obtain that goal.
