mtigas / libx264-max2.ffpreset
Created August 26, 2010 20:52
# My excessive ffmpeg conversion preset for high quality H264 files.
#
# Generally follows the "max" preset, with some values completely cracked
# out (me_range=32 *is* excessive). Leaves refs at 4 (since iPhone/iPad
# does not support higher values) and 8x8 DCT is disabled so that we
# end up with a file that is in the H264 Main profile.
#
# Save this as ~/.ffmpeg/libx264-max2.ffpreset
#
# Example use. (CRF determines filesize: lower CRF->higher quality and larger file. 22-24 results in ~1.5 to 2.0 Mbps.)

mtigas / video_convert.sh
Created October 13, 2010 19:37
#!/bin/bash
# Using `ffmpeg` to convert an arbitrary video file to an ipad-compatible M4V (h264+AAC)
# file. Mac-specific since libfaac has occasional audio glitches and the `afconvert` command
# is of a much higher quality (since it uses the system's Quicktime libs).
# Assumes ffmpeg and x264 (and other libs ffmpeg uses to decode various video formats
# you want) are installed.
#
# Easy mode:
# * Install homebrew: http://github.com/mxcl/homebrew

mtigas / key_strength_patch.py
Created December 15, 2010 01:04
Monkey patch to add key strengthening to django.contrib.auth user passwords.
"""
Adds key strengthening (via sha384 + large number of hash iterations) to the
default Django password implementation.
The number of iterations is stored along with the hash so that in the future,
the number of rounds can be increased for new passwords in the same system.
Standard Django hashes look like:
algo$salt$hash
