I'm aiming to reduce the bit rate of a video contained in a transport stream. The command (ffmpe.exe) is as follows :

ffmpeg -i "udp://" -map 0:v -c:v libx264 -b:v 256k -maxrate 256k -bufsize 256k -map 0:d -c copy -f mpegts "udp://"

The result is a tranport stream with the same bit rate. What I'm doing wrong? Thank you. sb


Place the -c copy before -c:v libx264. See https://superuser.com/a/1219824
