Run a command to generate a gif from the first minute of a video

We will want to run the following FFmpeg command: 
ffmpeg -i https://storage.rendi.dev/sample/sample.avi -vf "select='lte(t,60)*gt(trunc(t/10),trunc(prev_t/10))',setpts='PTS*0.025',scale=trunc(oh*a/2)*2:320:force_original_aspect_ratio=decrease,pad=trunc(oh*a/2)*2:320:-1:-1" -an -vsync vfr output1.gif

​
Use the same command in Rendi

curl --location 'https://api.rendi.dev/v1/run-ffmpeg-command' \
--header 'X-API-KEY: <api-key>' \
--header 'Content-Type: application/json; charset=utf-8' \
--data '{
    "input_files": {
        "in_1": "https://storage.rendi.dev/sample/sample.avi"
    },
    "output_files": {
        "out_1": "output1.gif"
    },
    "ffmpeg_command": "-i {{in_1}} -vf \"select='\''lte(t,60)*gt(trunc(t/10),trunc(prev_t/10))'\'',setpts='\''PTS*0.025'\'',scale=trunc(oh*a/2)*2:320:force_original_aspect_ratio=decrease,pad=trunc(oh*a/2)*2:320:-1:-1\" -an -vsync vfr {{out_1}}"
}'
Documentation for /run-ffmpeg-command
Running this command will return the command_id: 
{
  "command_id": "089dd36c-723c-4a0a-b68a-8e8cbcc1afd2""
}
The command now runs in Rendi and you can check its status:

​
Poll the command_id until it reaches status SUCCESS

curl --request GET \
  --url https://api.rendi.dev/v1/commands/{command_id} \
  --header 'X-API-KEY: <api-key>'
While processing the command will pass from status QUEUED to PROCESSING to SUCCESS

    }
}
When the status reaches SUCCESS Rendi will return the stored output file with it.
