Assume the following situation that occurred to me recently:
There is a slow computer A with lots of disk space (eg. an old computer that is used as a NAS) and a faster computer B with only little disk space. A holds gigabytes of video clips in many different files that you want to do some CPU intense processing on, eg. re-encoding to another video format.
So what you probably want to do for every video clip is the following:
1. download video clip from A to B
2. process video clip on B
3. upload converted clip from B to A
4. delete original (and converted) clip on B
It is assumed that B can ssh/scp into A and that public key authentication is used. Otherwise it would be necessary to enter the password for every individual file. Moreover it is assumed that A and B are connected by a sufficiently fast network.
A simple script (runs on B) that was used to perform the steps 1-4 can be found here. An additional example script is provided that uses ffmpeg to scale video clips down to 720p.
This blog is supposed to be a collection of random, unrelated, little ideas, thoughts, and discoveries, which I assume to be helpful to a negligible part of the world's population and wish to share out of pure altruism. If posts appear really weird, maybe you have the wrong kind of humor. Many of the posts are science/technology related. If you are opposed to that, stop reading here! Comments, criticism, corrections, amendments, questions are always welcome.
