"Deshaking" means fixing the video captured from camera hold in hands.
Is there open source video deshaker apart from
mjpegtools? Patch for
mencoder is preferred.
My current command line for processing video looks like:
mplayer video_from_camera.avi -nosound -vo yuv4mpeg:file=/dev/stdout -really-quiet | y4mstabilizer -n -a 0.8 -r 30 -s 100 | mplayer -cache 1000 /dev/stdin -noconsolecontrols -vf crop=500:380:70:50,denoise3d=3:3:5:5 -vo yuv4mpeg:file=temporary.yuv
y4mstabilizer is itself very unstable and often crashes (and it didn't work at all until I have patched memory allocation in it).
