Let’s talk a little more about aspect ratio. Always a lively topic everywhere I go, and regularly misunderstood by industry leading CCTV equipment manufacturers, engineers, and other video professionals. Should we correct, when do we correct, how do we correct, and of course the why. I’ve done a few short posts on the topic in the past (here's one), but this will be in a little more detail. Still writing on the fly, just going to break it down into a few posts over time.
That's a tall order, right? VLC from VideoLAN.org has become the go-to media player for most, as it can play so many things that Windows Media Player won't, and it's free. Well, how does it do that, play more than other players? The Libavformat and Libavcodec libraries, the same ones created by and for the FFmpeg project (and so many other multimedia applications).
DirectShow is one of Microsoft's multimedia frameworks, formerly known as ActiveMovie, which replaced Microsoft's earlier Video for Windows framework. VLC supports DirectShow-based input sources through a module (not very well, IMO, though), but the default Windows version downloaded from VideoLAN cannot reference 32-bit DirectShow filters installed on your Windows PC for audio/video decoding (i.e. filters/codecs registered in your Windows Registry), as the default version downloaded is x64.
As an example, a DCCTV video file exported from a GeoVision system to an AVI file may be using the proprietary GMP4 video codec. In order to play the video, you must install the GeoVision GMP4 codec necessary to decode the primary video stream; this is a DirectShow filter. DirectShow filters can only be referenced by applications that can leverage DirectShow, which we've established, VLC x64 cannot.
