The Blender (BGE) - side of rtsp support is committed [6f846da], now to the ffmpeg backend: Seems like a special case - couldn't the BlenderCAVE/remote-camera users who want RTSP do their own builds? That's a possible compromise, but then I would ask to at least have wiki pages on how to

This is a feature quality question. There are lots of stuff which is already used from FFmpeg (and which requires quite reasonable amount of time to maintain) and there are much more stuff which could be enabled as well. Main question here is: who's gonna to maintain this? And maintain means

What if the Blender game engine receives only a very simple (uncompressed pixel?) stream from a fifo and an external program converts the required format? Or instead of a fifo, maybe it is possible to use shared memory mapping. I'm sure it is possible in Linux but perhaps not in Windows. Is

@Fasekas: we are wrapping some of the functionality directly from the FFmpeg library so unless ffmpeg can do it I believe we can't. That's besides the point though, why to reinvent the wheel if we are already using a library that provides streaming. @Sergey And maintain means communicate with

I have a deck link card. And I've redirected the captured video from it to the v4l2loopback device. It can be done using bmdcapture + ffmpeg or gstreamer. Both work quite well. You can do it with melt too, but technically it uses ffmpeg to interface with v4l2. On Jul 16, 2014 12:23 AM, Fazekas
