问题 I want to load a video that has a soundtrack, and I want it to take an audio clip of a single spoken word and I want the clip inserted at different points in the video.

问题 I am able to use the moviepy library to add a watermark to a section of video. However when I do this it is taking the watermarked segment, and creating a new file with it.

Something like this: >> m = MovieGenerator() >> m.convertMovie('/path/to/movie/movie1.avi') >> print m.status >> 35 frames completed Is this possible (or recommended)? Does anyone have a working example of how to use ffmpeg as a subprocess? Once the conversion is happening, is there any way to "check in" on the status of the conversion (for

问题 Tried a lot of options and am running out of ideas. I was hoping someone here could help. I am trying to write some code in python that will extract frames (say every tenth frame) from a video (.avi or .wmv) and create a picture (.jpg preferably - but other formats will do). I have had no success and was wondering if someone could assist me in solving my problem by providing an alternative to what I have tried and failed. I have tried PyMedia (the example in their tutorial http://pymedia.org
