• Softwares for adding real time text to a video [on hold]

  30 juillet 2013, par user763410

  I am trying to add real time text (like weather information, stock quotes) to a video and broadcast it. My videos are going to be 2 hours long. I have been searching for decent softwares which can do the work for me. FFmpeg can do overlays only if text to be added is available fully before running ffmpeg code, so its not real time. I have not been able to able to get gstreamer to work on my hardware.

  So, My question is :
  Please suggest some softwares which can add (text)data to a video in real time.
  Please don't post comparisons as that will trigger moderator's anger ! I don't want to start a flame war. Purpose of the question is to make a list. Btw, this should work from command line rather than a GUI.

  (Ps : If the question is closed because of being "not cnonstructive, please answer it on my google docs page here.

  Thanks very much in advance.

• Some modifications for ffmpeg scripts

  21 mars 2021, par FoxFr

  I wish to modify the following script to put some options, obviously if you can explain ... is better my learning

  


  ffmpeg \
-i /dev/video0 \
-r 1 -stream_loop -1 -f image2 -i "/home/pi/videopi/map/map.jpg" \
-stream_loop -1 -re -i "/home/pi/videopi/bed.mp3" \
-filter_complex "[0][1]overlay=enable='lt(mod(t,20),10)'[v];[v]drawtext=textfile=/home/pi/videopi/gps.txt:reload=1:x=30:y=350:fontfile=/usr/share/fonts/truetype/lato/Lato-Black.ttf:fontsize=30:fontcolor=white[v]" \
-map "[v]" \
-map 2:a \
-c:v libx264 -b:v 4000k -maxrate 4000k -bufsize 8000k -g 50 -c:a aac \
-s 640x480 \
-f flv rtmp://a.rtmp.youtube.com/live2/[google_key_stream]


  


  My desired customization :

  


  

  • Add an another webcam (-i /dev/video1) : 30" video0 -> 30" video1 -> 10" image2 -> 30" video0 ... (a loop)

  


  • Add a png overlay on the final comp

  


  • how add a transparent png behind the text

  


  • plug an audio input (by jack) to add over the bed.mp3

  


  • save the file in same time of live (-f flv live.mp4 ??)

  


  


  The part -filter_complex is the most difficult for me to understand

  


  Thanks you very much for you help, it's for finish my personal and important project
