one-line tree in python

One-line Tree in Python

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

Concat MP4 files using AnnexB bitstream format

Concat MP4 files without transcoding to mpeg

  1. Use the h264_mp4toannexb bitstream filter to convert the mp4s (video steam only) into the AnnexB bitstream format

    ffmpeg -i input1.mp4 -vcodec copy -vbsf h264_mp4toannexb -acodec copy part1.ts
    # repeat for up to inputN
    
  2. Concat the files using cat

Python autovivicating tree with parent reference (variation of the one-line tree)

I was reading the gist @https://gist.github.com/2012250

I found the autovivification functionality of it pretty cool. If only I could have a parent reference...

Obviously this was not going to be a one-line tree. But that wasn't the goal

A simple variant:

from collections import defaultdict
