Re: Missing last frames

There are no errors. RVMedia write frames exactly at interval specified in TRVCamRecorder.VideoFramePerSec, as precise as possible. The only possible reason for missing last frames here is too large value of TRVCamRecorder.VideoFramePerSec: if it's not possible to encode the required count of frames...

Re: Hikvision Speed Dome

What is the problem exactly?
What version of RVMedia do you use?
Does the camera has username and password (there is a know problem with authorization on some cameras in RVMedia 5.3 and newer, we are solving this problem)

Re: RVcamRecorder drops connection to SQL server

Sorry, I do not understand how video recording may affect a database connection.
Maybe you can create a simple project that reproduces the problem?

Re: Snapshot from an axis ip camera stream doesn't work

Please re-test with RVMedia 6.0. It was uploaded today (and it's not yet announced).
You can re-run RVMedia installer, it can check for updates and download the new version.

Re: Why metods LoadRTFFromStream and SaveRTFToStream no Pictures

Please send me RTF file which is loaded without pictures (send to richviewgmailcom) or attach to this forum.

PS: if you use Lazarus, TRichView cannot load metafiles from RTF, because Lazarus does not have TMetafile class.

Re: Documents with Headers and Footers

For TSRichViewEdit controls created in code, it's necessary to call Loaded method:

Code: Select all

 SRichViewEdit1:=TSRichViewEdit.Create(Self);
 SRichViewEdit1.Align:=alClient;
 SRichViewEdit1.Parent:=TWinControl(Self);
 SRichViewEdit1.Loaded;

Re: Converting unicode code [ANSI format] to unicode glyphs

RVU_UnicodeCharToUTF16 and RVU_UTF16ToUnicodeChar do a very simple math calculation (using information which you can find in Wikipedia), they are platform-independent and Delphi-version-independent. You can use these functions even in applications that do not use TRichView: copy them to another unit...

Re: Converting unicode code [ANSI format] to unicode glyphs

If the question is how to display these characters in TRichView... First, you need a new version of TRichView, where UTF-16 is supported completely. To insert such codes in TRichView, they need to be converted to UTF16. TRichView includes a function for this in RVUni unit: RVU_UnicodeCharToUTF16: Ri...

Re: passing commands to FFMpeg

Yes, reading sound using FFmpeg is planned in future.

But I do not know when it will be implemented, because our next goal (after releasing RVMedia 6) will be FireMonkey and other platforms.

Re: passing commands to FFMpeg

RVMedia does not support reading sound using FFMpeg yet.
It only supports sound from microphones or other local devices.
