IPTV Live Video Encoding & Streaming with Video Overlay

Logo / Image / Text / Timestamp Overlay

During transcoding, it is possible to overlay customized logo and image on the video. To do that, go to channel Advanced Video settings -> Overlay, select a picture you prefer and set the position to put on the video.

Supported picture formats include bmp, jpg, png, gif, tiff, webp and svg. Choose a .png or .gif file if you want to overlay with transparent background.

Animated logo is also possible, by selecting an animated gif file as logo.

To overlay timestamp, enter %timestamp as overlay text.

Hardcode/Burn DVB Subtitle on Video

If you want to hardcode or burn dvb subtitle on video stream, rather than passing it through as a separated stream, for example when streaming rtmp, it is possible by IPVTL Advanced Format settings -> Custom Param tab -> Target Parameters box, enter "-filter_complex '[0:v][0:s]overlay[v]' -map [v]".

Note image or subtitle overlay requires to work with CPU transcoding. So don't use overlay in full GPU transcoding channels.
