06/01/2008: dhyana.pl/0.3
Here’s my latest update to dhyana.pl…
Change Log
- Added a title to the output image, which can be in a different font and colour from the rest of the text.
- Use Getopt to parse command line, and accept more options.
- Improved handling of certain dodgy WMV files, mostly thanks to Matt Pinkham.
- Improved use of FFMPEG
- Code straightened out to use functions — it used to be one big long mess.
- Added a help function — just run the program with the —help paramater.
Requirements
- Perl Getopt::ArgvFile
- Perl Getopt::Long ≥ 2.33
- Perl Pod::Usage;
- mplayer
- ImageMagick
Optional

All of the Perl modules can be found in CPAN, here is the FFMPEG site and here is mplayer. And don’t forget ImageMagick.

18/11/2007: Dhyana.pl Updated
This release works around errors in capturing screen shots from certain WMV files. It also changes the default geometry from 240×180+0+0 to “auto” which is an automatically calculated, hopefully appropriate, geometry.
19/08/2007: Sequential Video Thumbnails on Linux
So, I was looking for a way to create sequential video thumbnails (like this one) from a video file on Linux. I found that my options were severely limited. On Windows there are a plethora of tools capable of this fairly simple task, including Media Player Classic, but on Linux all I could find was QFrameCatcher. The QFrameCatcher website was inaccessible yesterday; today I managed to download the source code, but couldn’t get it to build.
Anyway, I decided it probably wouldn’t be very difficult to build my own so…
dhyana.pl
dhyana.pl is a small Perl script that co-ordinates mplayer and ImageMagick to create a lovely montage of thumbnails. (Dyhana — roughly pronounced as “jahna” — is the Sanskrit word for a deep meditation.)
