I am sorry.

Is my question worth answering?

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...

Well, waiting for a release.
And can you tell me what is the difference in these modes? Just to know.

Hi all!

I've met a problem: RVCamera.GetCamVideoMode returns duplicate resolutions (see attached screenshot):
What is the reason?
Is there a way to fix it?

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?

Partially.

The application hangs for 15-20 seconds if I press Start recording button while it tries to connect.
Once it shows an error "Video stream error" the applications starts to respond.

The similar problem exists in demo project VideoRecorder.

If I try to connect to non existing stream and then press Start recording button it hangs as well in TRVMFFMPEG.VideoEncodeFile at the same line glCriticalSection.SafeEnter;

I have a problem with RVCamRecorder (version 6.1). I connect to an rtsp stream via following lines: RVCamera.DeviceType := rvdtRTSP; RVCamera.URL := 'rtsp://127.0.0.1:8554/stream.sdp'; and then start recording: RVCamRecorder.OutputFileName := 'out1.avi''; RVCamRecorder.Active := true; Then I disconn...

Is there an access to this array?

How can I avoid copying img.Data to another class instance?

In my application I need to have a direct access to a frame bitmap. I draw frames by myself via OpenGL texture. RVCamera has an event OnGetImage, so RVCamera1GetImage is called when a new frame is decoded. RVCamera1GetImage has input parameter img and property img.Data that is a pointer to an array ...

I am greatly interested in using Gstreamer, but RVMedia supports only ancient version 0.1

What is the reason of not supporting version 1.0?
Are you planning to introduce a support of up to date Gstreamer libraries?

assigning RTSPTransport = [rvpeTCP,rvpeUDP]

Thanks, this helped!

But why these values are not set by default?

Yes, I do.
I even placed dlls in the same folder with apllication.

I used version 6.1 Tried version 7, but cant get video stream. I use VideoRecorder project. Changed in unit SampleCamList the following line (20): 'alias=CAM 1|' + 'url=rtsp://127.0.0.1:8554/stream.sdp|' + 'host=|' + 'port=|' + 'login=|' + But I get only message: Video stream error. What has changed...

MaxDelay must be the second property listed in RVCamera.FFMpegProperty in the Object Inspector.

But it isn't there:
