Images to video with ffmpeg

ffmpeg -framerate 24 -i im_%06d.png -s:v 752x752 -c:v libx264 -profile:v high -crf 20 -pix_fmt yuv420p video.mp4

The size can be different from the real image size but bigger and multiple of 16.

Modifying a file content with sed

sed 's/STRING/NEW_STRING/g' file

If you want to modify the file add -i to the command. We can also get the result in a new file by redirecting with > newFile. Example:

sed 's/tmax 2/tmax 10/g' conf200 > Input2.txt

svn diff visualization

The diff file between two revision can created that way:

svn diff -r 420:425 > file.diff

To visualize it nicely, you may use tkdiff for instance:

svn diff -r 420:425 --diff-cmd tkdiff

To make the diff on one particular file only:

svn diff Rockable.cpp -r 420:425 --diff-cmd tkdiff
