Hello
I'm testing the RVCamRecorder component and detected a problem that appears to be a bug.
In all tests performed, after completing the recording of a video (Rvcamrecorder.Active: = true), the component disconnects the connection to the SQL server.
This was detected even in the VideoRecorder example, where a simple query was inserted into a database on the Start button.
Has anyone ever come across this kind of 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?

Hi,
Use the VideoRecorder demo and insert into the OnClick of the "Start Recording" button a simple query to any SQL server database (using ADO).
example:
Query.Close;
Query.CommandText: = 'select * from test';
Query.open;
On the first run you will succeed, the next (ie after running RVCamrecorder.active true / false), will give a connection error.

Executable RVcamRecorder with the insertion of a simple query on the Start Recording button.
try
ADOConnection.Connected: = false;
ADOConnection.Connected: = true;
Query.Close;
Query.CommandText: = 'select * from group';
Query.open;
Showmessage ('First run. The connection is ok and the query runs normally.');
except on E: exception
begin
Showmessage ('after RVcamrecorder.active true / false, the connection fails and the query is not performed. Error returned =' + e.message);
exit;
end;
end;
a) Click on start recorder
b) After a few seconds click on stop
c) click start again.
I was unable to attach the demo application. Although small (1.1mb), the page informs that the file exceeds the allowed size.
