RTSP MPEG4 to RTSP h.264

Postby martyn1986 » Thu Aug 24, 2017 6:01 pm

Hi guys,

I'm trying to configure ffmpeg to convert an rtsp MPEG4 stream to a .h264 stream with the follow command in windows, can anyone shed any light where I'm going wrong please?

Code: Select all
ffmpeg -re -i rtsp:// -pix_fmt yuv420p -c:v libx264 -preset ultrafast -profile baseline -crf 18 -f rtsp udp://

however when I run the command I get the following error:

Code: Select all
C:\Users\Martyn>ffmpeg -re -i rtsp:// -pix_fmt
 yuv420p -c:v libx264 -preset ultrafast -profile baseline -crf 18 -f rtsp udp://
