Today, my company has asked me that can I convert FLV to wmv, avi, mpg etc.. Because they wanted to publish a wmv file on a web page, and it must have small file size, of course After that I search for it, and I see that , FLV file format is very hard to convert other video formats, especially with the sound of the video in it. So , I found a software called Riva FLV Encoder 2.0 which you can download it here. It does this job very easy and quickly. I just selected the FLV file at the “input” section. After that I wrote “videoFile.mpeg” to the output section. And TADAAAAAAAAAAA. MPEG file is ready to use with the sound..
