Recording video stream "as is" (without RVMedia's own compression)

Is there any way to save video stream (rtsp or smth like this) to a file "as is" without RVMedia's own compression of previously decompressed frames?

Sorry, no.

Is it just not yet implemented or not possible at all?

And could you explain why?
If you get video stream then you could just write it to disk without any changes, couldn't you?
Or I just don't understand something?

TRVCamRecorder does not know about video source. It just receives video frames from TRVCamera or TRVCamReceiver.

Ok, then may be TRVCamera or TRVCamReceiver can do it?

If you do not need to show this video, or to send using TRVCamSender, it's possible to implement recording using FFmpeg or GStreamer, so that they read input video stream and record a file. Moreover, it is possible to implement using their command line utilities.
Probably, this mode will be implemented in future updates of RVMedia, but currently it is not implemented.

I need to show video but I need also to record the stream as is, without any changes.
I am quite sure that this feature is very useful not only for me.

My case is so widespread (show video and record it at the same time) that many users will be glad to use this possibility. What is the sense of recompressing video to record it (if you do not want to change the stream)? You only get worse quality and processor overhead.

So, waiting for the implementation!
Thanks in advance!
