Definitely.

Mencoder does a nice job with some containers (particularly AVI), but
ffmpeg is probably more actively maintained and more widely applicable.

If you would rather spend weeks instead of minutes, you could try
using Python ffmpeg bindings:

    https://github.com/kkroening/ffmpeg-python

That will take a lot longer to develop and work and won't as well.

If you would rather spend years instead of weeks, you start with this:

    import sys
    infile = open(sys.argv[1],'rb')
    outfile = open(sys.argv[2],'wb')
    print("Converting %s to %s" % (sys.argv[1],sys.argv[2]))
    # some stuff goes here
    infile.close()
    outfile.close()

Then you study the specifications for the container formats you want
to support, the audio and video codecs you want to support, and fill
in 'some stuff'.  This will take, much, much longer to develop and
mostly just won't work, period.  You will learn a lot more, though. :)
