Hi everyone,

I will be away on vacation from July 26 to August 5. I will answer questions on the forum and by email, but responses may take more time than usual. I'll address difficult questions when I return.

I have almost completed a new version of TRichView, but I do not have enough time to ...

It worked as expected when I tested this demo. Probably, something was changed on one of Delphi 12.x updates.
Unfortunately, I was not able to check this problem yet. And I will be on vaсation till August 5th. I'll fix this problem when I return. Sorry for the delay.

The error occurs on drawing a document (not a background), and the only reason I can imagine is desynchronization between the document items and formatting information (the latter is updated when you call Format).

In your code, the most probable reason for this is
reader.RVData.NormalizeDocument ...

What version of TRichView and Delphi?

I don't understand what problems this code causes with images.

However, this code has problems.
1) You change properties of a text style, but this style may be used in different places of the document. This is not what the user might expect.
2) This code may lead to adding a new text style on each ...

1) If the exception on pasting happens in RTF loading code, it must not affect subsequent drawing. On exception, RTF loading is aborted, but the items that are already added must be formatted and must be displayed correctly.
If the error happens on some specific RTF, please send this RTF to me. If ...

Please create a compliable project reproducing the problem and send it to me.
I am afraid, without reproducing the problem, I cannot help.
I cannot even understand the problem. First, the topic was about a (handled) error when loading RTF. Then about exception on drawing. Then an error in a code ...

Do you use FFmpeg?
What version?
Does it happen on all RTSP streams?

What's the problem exactly?

(maybe it's an Uniscribe issue? Try assigning RVStyle.TextEngine = rvteWindows)

If the error text is shown on TRichView itself, this mean that an exception happens while drawing content.
Most probably. it happens because TRichView is not formatted.
Do not forget to call Format after loading.

Unfortunately, I can help only if I will be able to reproduce this problem.

Do you have TRVStyle linked only to this TRichView? If the same TRVStyle is linked with 2 or more TRichView, one of them can change styles in it, and others will be out of sync.

1) TRichView saves these bullets to RTF as simple pictures.
I do not remember what this solution was chosen instead of RTF's bullet-pictures. Most probably, MS Word resizes bullet-pictures in an uncontrollable way, and results do not look good for most pictures.
This is the reason why this list ...

It is intentional. TRIchViewEdit mimics TEdit and TMemo behavior. They, as I understand it, mimic the behavior of standard editors for the platform.

It looks like this is a bug.
Open fmxRVSelectionHandlesFM.pas, and change procedure TRVFMXSelectionHandles.Clear to:

procedure TRVFMXSelectionHandles.Clear;
begin
FLeftSelPt := nil;
FRightSelPt := nil;
FCaretPt := nil;
end;

Then recompile the packages (run "Install TRichView FMX in Delphi IDE ...

This exception happens in try..except block, and finally LoadRTF function simply returns False.
The exception is not noticeable unless debugging in Delhi IDE.
