A Feature rich AVI capture program

This allows the capture of AVI video from webcams along with high quality Audio. The audio can be taken from the default audio input device or any device selected from a drop down box.
If default audio is used (Audio option 1) the video is saved as a raw, un-compressed, avi. This can be subsequently compressed using the Compress raw file option.
If a specified audio device is used (Audio option 2), separate audio and video streams are joined together (muxed) using the open source program ffmpeg.exe (from https://sourceforge.net/projects/ffmpeg/ ). The resulting file is then compressed. A sliding scale is provided to synchronise the audio and video streams. I found adding a delay of +5/10ths of a second to the start of the video stream worked on my PC.
Single frame screen capture to jpg/bmp is available using Save Image.
The video capture devices are listed. This requires DirectShowLib-2005.dll ( from https://sourceforge.net/projects/directshownet/files/ )
Avi analysis of frame rate and audio stream is provided using ffprobe.exe from the ffmpeg download.

Remember to download the external files. ffprobe.exe, ffmpg.exe and DirectShowLib-2005.dll should be placed in c:\windows.

Tested on windows 10.

Note: Due to the size or complexity of this submission, the author has submitted it as a .zip file to shorten your download time. Afterdownloading it, you will need a program like Winzip to decompress it.Virus note:All files are scanned once-a-day by Planet Source Code for viruses, but new viruses come out every day, so no prevention program can catch 100% of them. For your own safety, please:
  1. Re-scan downloaded files using your personal virus checker before using it.
  2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.

If you don't have a virus scanner, you can get one at many places on the net including:McAfee.com
