Use ffmpeg to convert a video to a gif
ffmpeg -i input.mp4 -ss 00:00:24.000 -to 00:00:27.500 -vf scale=640:360 -r 20 cut.gif -hide_banner
# -ss: start time

tobadia / Some mkvtoolnix tweaks
Last active April 21, 2017 13:14
mkvtoolnix: remove 'header compression' for mkvmerge on old releases (>= 4.2.0 and below 6.x ?)
# The mkvtoolnix version that can be used on ARMv5 devices is an old 4.2.0-1 release.
# In this release, default is to switch on 'header compression'
# The solution is to take all tracks from a compressed file and have the corresponding headers uncompressed with the `--compression -1:none` (-1 is a wildcard for 'all tracks')
# This flag must be used for each input file, e.g.
mkvmerge -o "output.mkv" --compression -1:none "input1.mp4" --compression -1:none "input2.ac3" ...
# So, for adding subs.srt in an already existing mkv:

# Here I will keep a reminder of the steps to full wipe a OnePlus One device running CyanogenOS/CyanogenMod
# This is especially interesting on encrypted devices where I suspect partitions might get crippled over time
# Note: this guide assumes that you are already running the latest CyanogenOS version at the beginning (currently ZNH2KAS2X1).
# If not, dirty-upgrade to the latest version by flashing the update zip file from recovery and start from there.
# I will also assume that the current directory is the one where all the downloads are stored
# Step 0 : necessary stuff
