Stream your Windows desktop using ffmpeg

CLI, Codec, ffmpeg, free, MP4, Opensource, Transcoding, Video, VLC, Windows
I've already covered how to do this with vlc a while back in parts 1 followed by part 2. I just found out that something very similar in results can be done with ffmpeg. ffmpeg has recently added support for directshow filters which now allows one to capture the screen and stream and/or save it. Here is how you can do this: 1.) Grab a copy of the Screen Capture DirectShow source filter from Unreal Streaming Technologies. It's about half way down that page. They have both the UScreenCapture X86 Edition and the X64 Edition (depending on your OS installation). I used the 64 bit filter on a Windows 7 64 bit installation. 2.) Install the filter and make sure you make the following changes to your windows registry using regedit. The default frame…

But all that aside if you're interested in a minimalistic video player that can handle more codecs than VLC and is generally faster then give Movist a try.The unique thing about the player is that it allows you to switch codec engines between ffmpeg and quicktime based on file extensions. Oh and did I say it's FREE aswell :-).
