Publishing SMPTE bars for testing with ffmpeg

Sometimes you just want a general source for testing a new encoding config and don’t want to have to specify a source. For this the smptebars filter is very useful.

Here is how to push it out as an example to Wowza:

ffmpeg -re -f lavfi -i smptebars  -s 640×360 -g 25 -c:v libx264 -b:v 500k -an -f flv rtmp://wowserver.com/live/myStream

or for HD

ffmpeg -re -f lavfi -i smptehdbars  -s 1920×1080 -g 25 -c:v libx264 -b:v 4500k -an -f flv rtmp://wowserver.com/live/myStream
