Hi Damiano,
Thank you for your update.
At this moment, our SfRichTextBoxAdv control does not have support for
inserting videos. We have logged this as a feature request in our database. We
will implement this feature in any of our upcoming releases. We usually have an
interval of at least three months between releases. The feature implementation
would also greatly depend on the factors such as product design, code
compatibility and complexity.
Please let us know if you have any other questions.
Regards,
Arumuga Perumal S.
