Cannot play FLV ( fourcc FLV4 ) video – audio only

Published by:

Sypmtoms
When playing FLV files only video plays but there is no audio. Converting FLV to AVI or any other format doesn’t work. Sorenson Squeeze 5 can’t open FLV.

solution
The problem is an outdated FLVSplitter.ax.

First things first:
To be able to play FLV files in Mediaplayer or Winamp, we use ffdshow and a flvsplitter. You can download ffdshow here: http://sourceforge.net/projects/ffdshow The splitter can be found here: FLV Splitter 1.0.0.4

If you have ffdshow installed already and it (still) doesn’t work, the reason is that the FLV Splitter is outdated. Search for flvspiltter.ax on your c: drive. Then go there in a DOS prompt. Type in regsvr32.exe /u FLVSplitter.ax to unregister the old one. (if you get an error, it means you are not in the same directory!) Rename the file in flvsplitter.old and copy the new FLVSplitter (version 1.0.0.4) in the directory. In the DOS prompt now type: regsvr32.exe /u FLVSplitter.ax

Now it should play. (You may have to reboot or at least restart Sorenson)
