+PRPA
+====
+
+Apply a video-filtering chain with full exploitation of multi-threading.
+
+Usage
+-----
+
+./prpa [options] [file...]
+
+Options are one or more of the following:
+  -h [ --help ]           produce help message
+  -f [ --filter ] arg     apply a filter (see below)
+  -i [ --input-file ]     arg file to treat
+  -o [ --output ] arg     output file
+  -c [ --codec ] arg      output codec
+  -d [ --disable ]        disable parallelism
+
+Codecs
+------
+Codec name are 4-character codes that can be found on this page
+http://www.fourcc.org/codecs.php
+
+Codec name *must* match the output file extension.
+Exemples are:
+-c MP42 -o .avi # MPEG4
+-c MP42 -o .mp4 # MPEG4
+-c XVID -o .avi # Xvid
+-c theo -o .ogg # OGG Theora
+
+Note that MP42 and XVID are two of the quickest output codecs and thus will not
+be a bottleneck for the parallelism.
+
+Filter
+------
+
+Available filters are:
+* grey                Produce black and white ouput.
+* reverse             Reverse colors.
+* cartoon             Try to apply a "cartoon" effect (VERY SLOW).
+* drunk               Simulate alcool abuse.
+* count               Count frame per thread (debug?).
+* color=B,G,R         Apply the B,G,R color filter.
+* sepia               Apply a sepia effect.
+* blur[=X]            Blurs the video, X is the strength of the blur effect.
+* merge               Merge 2 videos pixel per pixel with a transparent effect.
+* interlace           Merge 2 videos, alterning between one pixel of each.
+* inlay=B,G,R         Inlay a video into another one at the place of the
+                      B, G or R color, trying to replace the whole color, not
+                      just the particular value.
+* strictinlay=B,G,R   Inlay a video into another one at the place of the
+                      precise BGR color asked.
+
+For the merge, interlace, inlay and strict inlay filters, at least two videos
+must be passed in the input files list.
+
+Examples
+--------
+
+./prpa -f drunk -f sepia -o bar.avi -c MP42 foo.avi
+./prpa -f blur=50 -f reverse -o bar.avi -c XVID foo.avi
+./prpa -f inlay=1,0,0 -o bar.avi -c XVID foo.avi
+./prpa -f strictinlay=255,137,42 -o bar.avi -c XVID orig.avi inlayed.avi
+
+time ./prpa -f drunk -f sepia -o bar.avi -c MP42 foo.avi
+time ./prpa -d -f drunk -f sepia -o bar.avi -c MP42 foo.avi
