[FFmpeg-user] Could not write header for output file #0 (incorrect codec parameters ?)

[USMAN AAMER]

Hi,
I am trying to stream videos with RTSP using the following command:

>ffmpeg -re -i v1.mp4 -c:v libx265 -an -preset slow -crf 30 -rtsp_transport
tcp -f rtsp rtsp://localhost:554/live.sdp

Streaming does not start and the following error occurred:
Could not write header for output file #0 (incorrect codec parameters ?):
Immediate exit requested
Error initializing output stream 0:0 --

How can I resolve the issue?
