Also we can transcode FLV to avi, mpeg, wmv formats with the help of Riva FLV Encoder.
We can extract the images form video files, cut the videos with a startoffset and a encode duration.
First I will explain how to transcode video files to FLV format files. Start the Riva FLV Encoder program. You will observe the Riva FLV Encoder options as shown below.
Suppose you have avi file named Tom and Jerry. Now browse the path of this file. Then at Output Directory browse the path where you want to save the FLV file(I have selected desktop). You can set the movie size also. Movie size option is at right hand side. Then click the Encode button. Then the transcoded file is saved at the specified directory as shown below.
Now let us transcode flv file named Tom and Jerry1 to wmv file. Procedure is same as above. But You have to change the extension of Destination Video File to wmv as shown below.
But when you play the file, it will give a message DIV3 codec is required to play this file. So download the above codec from the following site.

After installing the DivX Free 5.2.1 codec, we can play the above wmv file.
Onemore important thing. Suppose you transcoded flv file to avi file as explained above. But when try to play the file only audio comes but no video. You have to install the FFDShow MPEG-4 Video Decoder to rectify it.
