On the documentation on FFMPEG site it state under
16. Output Devices
SDL (Simple Directmedia Layer) output device.
This output devices allows to show a video stream in an SDL window. Only one SDL window is allowed per application, so you can have only one instance of this output device in an application.
To enable this output device you need libsdl installed on your system when configuring your build.
For more information about SDL, check: http://www.libsdl.org/
So my question is, how to build it with SDL support ? Offcurse I will need to incorporate SDL inside my C# project and use the output from ffmpeg with it.
