问题
I have a raw video frame source which I can access in Python. I'd like to create a MPEG4 video out of this, with MP3 background music.
What kind of tools and libraries are available in Python for such a task? Preferably I'd like to have an API for which I can feed output filename and then individual frames as 24 bit raw images.
回答1:
With OpenCV and the corresponding Python binding, you could use something like the function cv.WriteFrame. You could also use pyffmpeg, but that is geared more towards accessing individual frames from a video file.
回答2:
One of these should be able to do what you requesting:
http://code.google.com/p/pyffmpeg/
http://code.google.com/p/wffmpeg/
http://pymedia.org/

Because this question still shows up pretty high in relevant Google searches, here's the library I'm using now:
https://pypi.python.org/pypi/ffmpy/0.0.4
It is lightweight and still works.
Per Neal, OpenCV has the best libraries for editing, but does not (AFAIK) support MPEG.
