Re: RVMedia and DVR

1) Assign properties of RVCamera:
URL = <as you described>
DeviceType = rvdtRTSP

Re: Duplex printing error

There are printers that do not support copies. For these printers, SRVPrint handles copies and collating itself. There are printers that support copies but do not support collating. For these printers, SRVPrint relies on the printer when printing without collating, and handles copies and collating i...

Re: Hardware acceleration

To optimize drawing, try assigning TRVCamView.RenderMode = rvmrmOpenGL.
But if CPU load is caused by decoding inside FFmpeg/GStreamer libraries, it cannot be helped.

Re: ONVIF Events

Re: Get TRichView object data size

It's not a trivial task, because TRichView contains many objects. You can use FastMM to check the allocated memory before and after loading a document, see the accepted answer here: https://stackoverflow.com/questions/15622455/how-can-i-find-out-how-much-memory-is-used-by-a-specific-component-or-class

Re: Duplex printing error

In newer version of the components, if collate is turned off, and the printer supports copies, TSRVPrint allows printer to handle copies itself.

Re: [BUG] Strange table behavior

This is a TRichViewEdit limitation. When editing too long cells (higher than 30000 or 32000 pixels, I do not remember exactly), the editor sets the cell editor height equal to this limit, enable scrolling in it, and hatches the remaining area.

Re: Identify RTF or RVF

Change LoadRVFFromStream to LoadFromStream(Stream, rvynaAuto);

LoadFromStream can detect RTF and RVF.

For example, a master/detail relationship may be created using properties of datasets (see "4 - Master-detail predefined" demos for FireDAC...

Re: Audio and Video synchronization

Yes, there is TRVCamReceiver.VideoLatency property, but it does not delay video like AudioLatency do for audio. We are working to modify VideoLatency to work like AudioLatency. Ilya is working on it, he said that it can be done in a couple of days, but I cannot say when a new version will be uploade...
