Is it possible to add a watermark when creating an auto egress room composite recording?

Thanks for reaching out, Anne. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.


Yes, you can add a watermark to auto egress room composite recordings by using a custom template. This involves specifying a `custom_base_url` in the egress configuration, which points to your custom HTML template. The template can include the watermark as part of its design.
To implement this:
1. Create a custom HTML template that includes your watermark (e.g., text, image, or logo).
2. Configure the `custom_base_url` parameter in the egress request to point to your template.
3. Use the LiveKit CLI's `test-template` command to validate your template and ensure the watermark appears correctly.
If you need further guidance on creating the template or configuring the egress, let me know!
