how to get the output of the ffmpeg to the var and upload it using curl, like here

ffmpeg -i test.mp4 -f avi pipe:1 | cat > out | curl -F document=@"$out" https://api.telegram.org/bot<token>/sendDocument?chat_id=<chat_id>

In this command test.mp4 is input file and out put is out

Here I am trying to store output of ffmpeg to a var named out and then trying to upload it to telegram directly but nothing happen. Is there any way to do it ?

This is an unusual way of using ffmpeg. I think there might be a way of using stdout as the output of ffmpeg command but it is a dirty way if any! You should set the output file of ffmpeg command and then send this file by curl. Then you can delete the file if you want. You can put these commands in a .sh or .bat file and run it using a single command:

ffmpeg -i test.mp4 -f avi out.mp4
curl -T out.mp4 https://api.telegram.org/bot<token>/sendDocument?chat_id=<chat_id>
rm out.mp4
