+@section How could I read DirectShow files?
+
+If you have built FFmpeg with @code{./configure --enable-avisynth} (only possible in MinGW/Cygwin platforms)
+then you may use as input any file that DirectShow reads.
+(Be aware that this feature has just been added, so you will need to support yourself for any query)
+
+Just create an "input.avs" text file with this single line ...
+@example
+  DirectShowSource("C:\path to your file\yourfile.asf")
+@end example
+... and then feed that text file to ffmpeg:
+@example
+  ffmpeg -i input.avs
+@end example
+
+For ANY other help on Avisynth, please visit @url{http://www.avisynth.org/}.
