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

Question

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-%010d.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-%010d.avi"

It started to record video but with errors:

Misunderstanding

Answer 1

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.

See FFmpeg Wiki: Map.

Answer 2

I faced the same issue then I just replaced the -c copy option with a -r $number option.

ffmpeg -i input_movie.avi -r 30 ouput_movie.mp4

Note: If it still not works, you can try another method by upgrading your OS in order to pull new features and updates.

# -- firstly upgrade packages
sudo apt update && sudo apt full-upgrade

# -- retry conversion
ffmpeg -i input.avi -c copy output.mp4

If -c copy does not work, try the -r $number option.

Bonus: Sometimes you would like to use the old fps for $number. get the old value like this

ffmpeg -i input_movie.avi 2>&1 | sed -n "s/.*, \(.*\) fp.*/\1/p")

Or just join with the main command

ffmpeg -i input_movie.avi -r $(ffmpeg -i input_movie.avi 2>&1 | sed -n "s/.*, \(.*\) fp.*/\1/p") ouput_movie.mp4

Sometimes you just need to remove -c copy and your conversion will work very very well. It is due to the stream type. You can not simply copy an avi stream to a mp4 container. I think it is normal that it would not work. As we talk about conversion, you must let ffmpeg convert the stream to a new stream type. – Unruly
