Extract Images from Video Using ffmpeg

I have this video which I want to extract images from it. To extract images from a video type

For extracting images from a video:

ffmpeg -i foo.avi -r 1 -s WxH -f image2 foo-%03d.jpeg

This will extract one video frame per second from the video and will output them in files named foo-001.jpeg, foo-002.jpeg, etc. Images will be rescaled to fit the new WxH values. You can omit the -s option in case you do not know what size to put.

Viewing DAT Files in DVD or VCD using Mplayer Command LIne

It was about ten years ago that I use command line to watch VCD/DVD. But somehow rather after years of not using VCD/DVD disks, I forgotten the simple command. Sadly last night I had to resort to using the DVD player to play my kids’ childhood videos (as you guessed it, my wife and kids enjoyed the video). So today, I decided to post this  command line for future reference.

Simply pop in the VCD/DVD in the laptop DVD drive and open a terminal console. After that type:

#mplayer vcd://1

to play track 1

or

#mplayer vcd://2

to play track 2

If it is a DVD disk, replace the word vcd with dvd. That’s it. Thanks for reading. 🙂
