ffmpeg: Could not find tag for codec none in stream #1, codec not currently supported in container-CodePudding

I'm trying to record video from my ip camera stream with ffmpeg in command line

fmpeg -rtsp_transport tcp \
>  -i rtsp://192.168.0.250/stream1 \
>  -c copy \
>  -map 0 \
>  -f segment \
>  -segment_time 60 \
>  -segment_format mp4 \
>  "/home/video/stream-0d.mp4"

and got the next output:

Tried some different options like -c:v libx265 or -c:v libx264 but it does not works the output is a little different. But the main error is the same:

Could not find tag for codec none in stream #1, codec not currently supported in container
Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument

UPD: Tried the next command:

 ffmpeg -rtsp_transport tcp \
 -i rtsp://192.168.0.250/stream1 \
 -c copy \
 -map 0 \
 -f segment \
 -segment_time 60 \
 -segment_format avi \
 "/home/video/stream-0d.avi"

It started to record video but with errors:

CodePudding user response：

Stream #0:1 is unknown data, but the MP4 muxer does not know what to do with that.

Map only the video by changing -map 0 to -map 0:v.
Or keep -map 0 and omit the data stream by adding -map -0:d.
