Added mpeg1 support! This will give you much smaller files at a similar quality level.
The quality sliders are unique levels for each encoder, so a quality 50 mjpeg might look more like a quality 70 mpeg1.
ffmpeg.exe and ImgStreamCreator.exe need to be in the same folder.
If you've already downloaded a previous version of this tool, you'll only need to download the new ImgStreamCreator.exe file
