TRVCamera.FillVideoDeviceList suggestion
This function is very handy to get a list of webcams or monitors. It would be great if this could also be used to get a list of visible windows for use with DesktopMode=rvdmWindow; Here's the code for it I am using: DWORD dwThreadId = GetCurrentThreadId(); HDESK hDesktop = GetThreadDesktop(dwThreadI...

TRVCamRecorder.VideoAutoSize not working
When the TRVCamRecorder is connected to a TRVCamera with DeviceTpe=rvdtDesktop the TRVCamRecorder does not set its VideoWidth and VideoWidth automatically. I figured out a workaround when using DesktopMode=vrdmWindow by using GetWindowRect() to get the size of the window I am capturing, but how can ...

Assigning video codec
I understand that the function GetListOfAvailableFFmpegVideoCodecs() fills AList with the available codecs. However AList is a TStrings type. How can one of the values in the list be assigned to TRVCamRecorder.VideoCodec? Can you provide an example?

Re: Video Created has Blank (black) for 1st Frame
I am starting the camera before starting the recording, but I still get a black frame at the beginning. I am capturing a continuous video stream to multiple files and in order to play them back seamlessly, that black frame at the beginning of each video file is a real problem. Do you have a timefram...

Re: Significant delay with PlayVideoFile
This problem disappeared on it's own. Not sure what the cause was.

Updated Documentation
I am very much interested in your RVMedia component, but there are tons of properties to the various components that are not anywhere described in the documentation. Any plans to update your documentation in the near future? I think you have a very powerful component, but with the lack of documentat...

Saving video to AVI
I understand your current version can only safe video streams to mjpeg format. Are there any plans of allowing different formats (e.g. AVI)? If so, do you have a timeframe available?

Motion Detection using TRVCamera
I noticed the properties MinChangeAreaSize and MaxChangeAreaCount in the TRVCamera component, so I am assuming it's possible to do some kind of motion detection processing, but I've been unable to find any documentation on how to do this. Can you please provide some guidance? I'd like to save the in...

Saving Video to File
Is it possible to save the video to file with either the TRVCamReceiver or TRVCamView components?

Controlling playback
Is there a way to control the playback of a video file? I have only been able to find PlayVideoFile(), but nothing to control the playback (pause, play, seek, etc...).
Thanks

Significant delay with PlayVideoFile
When I execute PlayVideoFile(), it takes in excess of 10 seconds before the video is being displayed in the associated TRVCamView. I did set the DeviceType =rvdtFile. Curiously the StartVideoFile event never gets triggered (even after the video starts playing). The video I am trying to play was prev...

Re: Pause, rewind, etc.. of live video stream
My approach to implement this was to buffer the stream (either to memory or a file) and then playback that buffer.
I haven't been able to find any functions in RVMedia to control the playback of the video file (pause, stop, seek, etc...).

Pause, rewind, etc.. of live video stream
I am looking for a way to control the video of a live video stream (from a USB camera) that would allow the user to pause, play, skip forward/backward. Variable playback speed and reverse playback would be nice, too but its not a must. Is this something that can be accomplished with RVMedia? If so, ...

Playback of mjpeg file
I have tried, but haven't been able to playback the mjpeg files that are created with the RVMedia components. Actually, the mjpeg extension isn't even recognized by any of my video player applications (including VLC). Is it just a matter of changing the extension (to what)? Do I need a codec to play...
