There is also an option to encode the video and stream it at the same time(live encoding), but you need a powerful computer in order to do it. This way we are just streaming the video, not encoding it which in our case is very useful because our computer is not powerful enough. The speed of the stream is defined with -re which tells FFmpeg to stream at the speed as the video would be playing(FFmpeg default setting is to stream as fast as possible). Here, we are copying the video(-c copy) and streaming over UDP to the destination 192.168.2.10:1234. So, we already encoded the video files and now we want to stream them.

To encode raw content (picture sequences, uncompressed video streams, etc.) you can use the free video encoder FFMPEG (learn more here: ).
