Creating MPEG4 video file with Python from raw fra

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.
