Updated the Watermark page to show the configured or not status at the top together with the watermark itself and the selected position.
Videos longer than 1 hour will have their duration displayed correctly.
Adjusted the width of the Status and Video Details columns in the Videos page.
Updated the documentation in regards to how to obtain the custom payload data from the webhook.
Updated the REST API documentation.
Pipe now checks if the recorded stream contains video and only then applies a watermark (if one is configured). This prevents an issue that caused streams to not get converted if they contained only audio.
Fixed issue with video email notification being sent multiple times if certain conditions were met.
