Detect identical & black frame in video with ffmpeg?

Thumbnail creation is a very needed feature for any social networking site. Obviously, ffmpeg is the ideal solution for generating thumbnail.

Problem-1: Detecting identical thumbnails

Fortunately, we have a good solution--libpuzzle. It would be ideal to have a filter in ffmpeg for that.

Problem-2: Detecting black/dark frames

I'm still keenly looking for a solution tied up with ffmpeg. When Google turned no help, Heleena (my wife) solved it by calculating average luminance value of the frame and ignoring the frames based on certain preset threshold value--which worked better at that time.

Humble Award - Dr. A.N. Sreevatsan

Dr. A.N. Sreevatsan , ENT specialist located in Adyar, Chennai is one of the gems available in medicines. No assistants in his consulting room and he'd take at least 15mins for every patients. So far I have referred many and all are happy with his approach. Every wannabe doctor should visit him personally to understand his approach. I wish him to be more famous than now. Update (2010-11-21) : Added link to Google Map Keywords : Sreevatsan, Srivatsan, ENT, Adyar, Chennai, Hospital, Doctor

How to interview a candidate?

How to interview a candidate/programmer -- Version 0.0.1 Note : It's based on my process of short-listing candidates/programmers and experiences so far in selecting and building my great team. I'll expand it whenever I get time and will amend versions. Not many of you were wise in the way the world judges wisdom. Not many of you had great influence. Not many of you came from important families. But God chose the foolish things of the world to shame the wise, and he chose the weak things of the world to shame the strong. - St. Paul Core facts Interviewing is a serious effort and interviewing has great career prospects. Take it as a serious profession. Interviewer/interviewee – no one is genius. You cannot find a person who knows everything. You're not a foreteller and so you cannot identify people by appearance. That's the need for the interview. No interview question is right or wrong. You need to take good decision based on many factors—not just...
