To lameboyadvance - many thanks and well done for your efforts.
At first I got an error when I hit the DL button, but it turned out that my version of FFMPEG.exe wasn't as fresh as I thought it was
.
Perhaps Napper and Ripper can follow a similar process by using FFMPEG instead of RTMPdump.
You mention that you aren't interested in maintaining Iviewer - would you consider sharing the source code so that others can keep the ball rolling?
