• ffmpeg is adding an extra new line into a box

  4 août 2017, par newbie123

  I’m overlaying weather data over my webcam stream. I put a background box filter, but the padding between the text and the box is uneven. There is "a new line" of extended box bellow the text.

  

  Why is that ? There are no empty lines in a text file I’m providing to ffmpeg. Here is my code for the ffmpeg :

  ffmpeg \
  
  -f lavfi -i anullsrc \
  
  -rtsp_transport tcp \
  
  -i "$SOURCE" \
  
  -vcodec libx264 -pix_fmt yuv420p -preset ultrafast -g 20 -b:v 1000k \
  
  -vf "drawtext="fontfile=${FONT}":textfile=${textfile}:x=5:y=55:reload=1: \
  
  fontcolor=white:fontsize=${FONTSIZE}:box=1:boxborderw=5:boxcolor=black@0.5" \
  
  -threads $THREADS -bufsize 512k \
  
  -f flv "$YOUTUBE_URL/$KEY"

  EDIT :

  I found out what the problem was. I was using printf "%s\n" "$variable1" "$variable2" to create a text file. Printf %s\n automatically prints each variable into a new line. The solution was to print the last variable without the new line. Code example :

  #!/bin/sh
  
  LC_CTYPE=en_US.utf8
  
  
  
  # Get APRS weather data from aprs.fi
  
  
  
  wxstation="S55MA-10"
  
  name="Juršče, Pivka"
  
  
  
  
  
  # Basic weather data
  
  temp="$(wget -q https://aprs.fi/weather/a/${wxstation} -O - | grep Temperature | egrep '[-+]?([0-9]*\.[0-9]+|[0-9]+)' -o)"
  
  humidity="$(wget -q https://aprs.fi/weather/a/${wxstation} -O - | grep Humidity | egrep '[-+]?([0-9]*\.[0-9]+|[0-9]+)' -o)"
  
  wind="$(wget -q https://aprs.fi/weather/a/${wxstation} -O - | grep Wind | egrep '[-+]?([0-9]*\.[0-9]+|[0-9]+)' -o | sed -n -e 2p)"
  
  rain="$(wget -q https://aprs.fi/weather/a/${wxstation} -O - | grep Rain | egrep '[-+]?([0-9]*\.[0-9]+|[0-9]+)' -o | sed -n -e 1p)"
  
  
  
  # Telemetry
  
  radioactivity="$(wget -q https://aprs.fi/telemetry/a/${wxstation} -O - | grep Radioactivity | egrep '[-+]?([0-9]*\.[0-9]+|[0-9]+)' -o | sed -n -e 5p)"
  
  
  
  printf "%s\n" "$name" "Temperature: ${temp}\°C" "Humidity: ${humidity}\%" "Wind: ${wind} m/s" "Rain: ${rain} mm/h"
  
  printf "Radioactivity: ${radioactivity} uSv/h"
