FFMPEG rtsp stream add timestamp to output file

Question

I'm trying add timestamp to output file from FFMPEG but I'm getting this error.

Filtergraph 'drawtext=fontfile=/usr/share/fonts/truetype/ttf-dejavu/DejaVuSans-Bold.ttf:text='\%T': [email protected]: x=7: y=460' was defined for video output stream 0:0 but codec copy was selected.
Filtering and streamcopy cannot be used together

And my command is:

 ffmpeg -i rtsp://admin:[email protected]:554/11 -vf "drawtext=fontfile=/usr/share/fonts/truetype/ttf-dejavu/DejaVuSans-Bold.ttf:text='\%T': [email protected]: x=7: y=460" -acodec copy -vcodec copy test.avi

And the output:

Where I'm doing a mistake ?

Thank you for all reply :)

-vcodec copy == streamcopy. You need to re-encode to add a text overlay so choose one encoder like libx264 etc. — aergistal

Thank you. I changed it to -vcodec libx264 it said Illegal instructions. — kernel252

Bad example, it might not be available in your ffmpeg build, try another (ffmpeg -codecs) — aergistal

Please re-read the guidance for the tags you've used. This is clearly a question about using FFmpeg, not about programming, so is off-topic for Stack Overflow. It might be suitable for Super User or Unix & Linux: consult the Help Centre for the site before you post. — Toby Speight

I came across this command posted for ffmpeg (thanks to github user reidransom):

ffmpeg -i video.mov -vcodec libx264 -cmp 22 -vf "drawtext=fontfile=DroidSansMono.ttf: timecode='09\:57\:00\:00': r=29.976: x=(w-tw)/2: y=h-(2*lh): fontcolor=white: box=1: boxcolor=0x00000099" -y output.mov

Keep in mind it's one complete line. The \ characters in the timecode option are there to enable the :'s as chars. r sets the frames per second capture rate.
