Video file image capture with ffmpeg

In my work yesterday I had to fix a flash preview option for a website I was doing.
(Cant name the site.) The people (pronounced 'poephol' ) were making the web user who visited their site automatic download loads of video content.

This made the client's website a bit slow, and created lots and lots of bandwith consumption. Anyway. They realized their mistake asked me to send thumbnails of the vidoes.

At first I asked the account manager to send me screenshots of the videos. But this was not going to work, as she pasted it into a word document. Then I thought - "There should be an easier way todo this." - and there is.

1) Install ffmpeg
Debian, Ubuntu:
sudo apt-get install ffmpeg

2) Replace the video and image filenames in the command listed below with your video and image and paste into a terminal.

ffmpeg -y -i video.flv -vframes 1 -ss 00:00:05 -an -vcodec png -f rawvideo framepic.png

3) You may have noticed that the "-ss 00:00:05" indicates to capture the image after 5 seconds. You can change this to the frame you want to capture.

4) After creating the PNG, I used the convert function of ImageMagick to make the file a JPG.

ImageMagick converts your images from the command line

I am sure there are many image converting programs on the internet and some are probably a lot more user friendly, but I recently used ImageMagick to resize some family photos to send to my family. (I know putting this on Facebook or Picassa would have solved this issue, but not everyone use these as often as email)

As I am sure most users know that image from cameras can be quite big and this tool will convert those images to the size and quality you desire.

All you need todo is install ImageMagick
Debian, ubuntu:
sudo apt-get intstall imagemagick

then run the convert command with your preferences
convert image.jpg -resize 800x600 -quality 70 -interlace PLANE image2.jpg

Terminator Terminal

I have been using "terminator" for a while now a find it a very useful tool when monitoring logs on remote servers. Terminator enables you to have several terminal clients open in the same window. Just right click the window and select "split vertical" or "split horizontal" and it splits your window.

Debian, ubuntu:
sudo apt-get install terminator
