Video how can i record game scene view?

hi there. first, sorry about my bad english conversation.
i'm trying to record game scene in Universal Windows Platform and using WebRTC.
i'm searched google, and a lot of contents are say 'should use asset store' or 'using ffmpeg'.
but i don't know how to using ffmpeg in unity, and I'm not sure I can use it for things in the Asset Store.
i can take a game screen shot, and another project test using sample code, Many screen shots could be saved as png files. but if i build UWP, .NET framework is not contain thread(maybe), so occured error.
i don't know how to convert from png to avi or mp4. help me please.

 

knock knock?? anyone don't know this problem...?

 

Try the Unity Recorder asset.

 

Thanks to your reply. but it can't use after UWP build environment. is not other way???

 

@Kideokk, it can, i use it all the time to record Hololens videos.

 

"The Unity Recorder is an Editor-only tool that captures video and animation data during gameplay. ",how to use it??Look forward to your reply...

 

the Unity recorder is no longer available??? Any alternatives?
