Re: Need to send video stream over the internet (RVCamSender, RVCamReciver or smth else?)

2. I've downloaded the latest version and recorded a test with the last compiled demo version (30.05.2020): https://yadi.sk/i/wBUPrTPjrD9QsQ

You can see video jittering (on 7-8 second) and big video latency on first connect and small after reconnect.

Please, fix this issue.

Need to send video stream over the internet (RVCamSender, RVCamReciver or smth else?)

I need to send video stream that I recieve with RVCamera (either USB Camera or RTSP stream) over the internet to another client/clients and display it in my client application. I do not use RVCamView because my application is OpenGL based and I get frame via TRVMBitmap.AssignRVMBitmap() inside RVCam...

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

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 reco...

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

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

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

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?

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?

Video device list can not be updated

There is a procedure WebCam.CreateVideoDeviceList; that creates video device list. The problem is that it is called only on the start of a program. So if a new web camera was attached via USB port after the start of your program you can't use it. I had to make a workaround by creating a new procedur...

Re: RVCamRecorder hangs on RVCamRecorder.Active := false;

I moved line RVCamRecorder.Active := true;

inside RVCamera1GetImage(Sender: TObject; img: TRVMBitmap); event handler.


It looks like that it solved a problem.

Is this a correct work-around?
