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: RVCamera.GetCamVideoMode returns duplicate resolutions
Well, waiting for a release.
And can you tell me what is the difference in these modes? Just to know.

RVCamera.GetCamVideoMode returns duplicate resolutions
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?

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?

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

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

Re: RVCamera1GetImage(Sender: TObject; img: TRVMBitmap);
Is there an access to this array?
How can I avoid copying img.Data to another class instance?

RVCamera1GetImage(Sender: TObject; img: TRVMBitmap);
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 ...

GStreamer version
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?

Re: Testing RVCamera - Video blurred
But it isn't there:MaxDelay must be the second property listed in RVCamera.FFMpegProperty in the Object Inspector.
