While some decorders for codecs used for screen recording are delivered with ffsdhow tryouts I'm missing some newer ones.
One of the best compression codecs for screen recording is actually ScreenPressor. It would be great if the free decoder could be intregrated into ffdshow so that everyone who uses ffdshow is able to watch videos which were made with the ScreenPressor-Encoder.
Download option and more information about ScreenPressor: http://www.infognition.com/ScreenPressor/
The exe-file you can download there can be decompressed simply by tools like 7-Zip (http://www.7-zip.org/).
In the exe-file there's also a license.txt file included which allows everyone to distribute the decoder for free.
I've attached a zip file with all the files which are included in the exe file. You can use it for decoder installation an integration into ffdshow.
