Broadcasting marquee with RTSP stream

[eggbeater]

Salutations,

I have a Raspberry Pi camera that I'm piping to VLC to broadcast via RTSP. My intent is to use marquee in the bottom-left corner to broadcast time/date and weather conditions by using a text file. The problem I'm running into is I cannot get the marquee to show up on the stream no matter what code I use. Here is what I have currently:

Code: Select all

libcamera-vid -n -t 0 --inline --width 1280 --height 720 --bitrate 3000000 --rotation 180 --framerate 30 --intra 5 -o - | cvlc stream:///dev/stdin -vvv --sout '#transcode{soverlay,sfilter=marq{marquee="Text here",color=16777215,position=10}}:rtp{sdp=rtsp://:8554/}' --no-audio :demux=h264

What am I missing to get the marquee on the stream? Thanks in advance for any assistance!

You need to select video transcoding parameters.

You need to select video transcoding parameters.

Thank you for the reply! Please pardon my ignorance. What would the parameters be?

I have tried setting the width, height, fps, vcodec, and vb parameters with no success on any front. I've tried several different combinations of parameters. I cannot find anything in the wiki that defines what parameters need to be set for transcoding, or any that need to be associated with the marquee parameter.

Is this something that VLC can do over an RTSP stream, or is it just for local video preview?
