Re: Video stream error on trying to open udp://127.0.0.1:54000

Will http:// prefix work for udp stream?

You mean http://127.0.0.1:54000?

Re: One sender > multiple recievers demo project

I don't know the number of clients that will need to recieve video from sender. Theoretically I can create new TRVCamSender instance each time a client is connected to the server. Do you think this way is more optimal than using TRVMediaServer? Why do you consider placing TRVMediaServer and TRVCamSe...

One sender > multiple recievers demo project

Is there any example or demo project on how to build an application capable to send the same video to multiple recievers?
Similar to SendAndReceive\TwoApps, but not limited to a single reciever.

Thanks in advance!

RVCamera doesn't show video if VideoDeviceIndex is set and SetCamVideoMode(0) is called before PlayVideoStream

Found an issue with RVCamera. In my project I should set RVCamera.VideoDeviceIndex and call RVCamera.SetCamVideoMode() just before RVCamera.PlayVideoStream. The issue is that if I pass 0 to RVCamera.SetCamVideoMode() then video is not shown (and RVCameraGetImage() is not being called). If I pass any...

Re: Access violation in TRVMFFMPEG.DeinitDecode function and Range check error in MD5Encode procedure

Yes, I see. But still we can get info from previous calls.

Is that enough to fix the problem or should I do smth else?

And what would you say about access violation errors?

Re: Access violation in TRVMFFMPEG.DeinitDecode function and Range check error in MD5Encode procedure

Yes, but if we open the source code of md5() we will see that S is directly passed from md5() to MD5String() and the value of the parameter of md5() is shown in call stack, isn't it? function md5(S: String): String; begin {$IFDEF MRVDELPHIXE8} Result := System.Hash.THashMD5.GetHashString(S); {$ELSE}...
