I'm trying to create small batch procesing tool that will be able to convert various video files to Flash Video files *.flv.
I know ffmpeg can do that, but I dont know how to link my app with ffmpeg. I only know VB.net (03,05) so i can not edit ffmpeg directly. I know I can use command line to send request to ffmpeg.exe but I do not know how can i get the esponces to a) get info from the file b) to see the file convertion progress c) to find out if file is converted ok.

Can some one help me out?
