I want to convert video files(.wmv and .avi) uploaded on my site to get converted to .flv. Searching the web I found ffmpeg( is a command line software which does the required conversion. But i don't know if it can be used with .NET. If it can be used then how..? If not then what is the other solution...?Can anyone help..?

Thanks in advance...

Convert .wmv or .avi files to .flv file using ASP .NET

by packer.lean In reply to Convert .wmv or .avi file ...

Hey its working for me. There are some sites e.g. where they give already built dll which we can easily implement in our project. All such dlls are actually wrapper to the free tool ffmpeg.exe which can convert videos and audios from one format to another. So i thought to use the tool itself instead of the wrapper dll. I have tried very simple example n its working for me so thought to share it it with all.

Download ffmpeg.exe from ( you will get a dll along with it (pthreadGC2.dll) keep both the exe and this dll together.

FFmpeg Documentation ( will be required for the syntax.

If you run it via command prompt then this is the syntax

ffmpeg -i inputfilename outputfilename

If it is to be executed via .net then Process.Start can be used to execute an executable.Do remember to give write permission to the asp worker process on the folder where the resultant flv file will be saved. If you dont then the program will run without any error or warning but output file will not be produced.

One more thing it do not convert .wmv files to .flv . Is there any way out to it........?
