+Sample post processing script to convert videos after download
+==============================================================
+
+This script is a post download processor for gPodder. It can convert mp4 and 
+mov movie files into an avi format that can be played on the COWON IAUDIO 
+X5(L). It should also be able to support other players with some minor changes 
+to the "convert_video_iaudio-x5" file.
+
+Installation:
+ * Copy "convert_video_iaudio-x5" and "gpodder_download_complete" to a location
+   in your $PATH (i.e. /usr/local/bin or ~/bin)
+ * Set the gPodder "cmd_download_complete" advanced setting to the location
+   of the "gpodder_download_complete" script

+Initial announcement:
+
+I've whipped up this little script to convert downloaded videos into a
+format that is supported by my IAUDIO X5(L). It's still got some gaps
+in it but it does take away some of the manual process of getting
+video's onto my player. While I'm not sure that this is the intended
+direction for the gPodder application, it might make a nice addition
+to the gPodderWiki.
+
+You can download it here:
+http://www.casedogdesigns.com/gpodder_convert_video/
+
+The script uses the post download hook by setting the advanced
+configuration variable "cmd_download_complete" to the
+gpodder_download_complete script.
+
+Once the download is complete the movie is converted onto the desktop.
+A zenity progress bar is shown while the conversion takes place.
+Ideally, the new file could replace the original in gPodder so the
+user would need to manually copy the file to their device, but this
+requires changing the file extension and I haven't found a clean way
+of doing this. So, for now the video must be manually put onto your
+player.
+
+Anyway, I think its a good starting point. It should be able to
+support video types for other devices by changing the mencoder
+parameters in the convert_video script.
+
+Let me know if you find it useful or end up making any changes.
