    9 août 2017, par user3354787

    I am running a robot that uses fmpeg to send straming video to letsrobot.tv You can see my bot on the website called patton II. I want to overlay a video HUD on the stream.

    I have found a link explaining how to do this, however I do not know how to do it with a streaming video as input instead of a single image file.

    This is the command that is currently being used to stream the video :

    overlayCommand = '-vf dynoverlay=overlayfile=/home/pi/runmyrobot/images/hud.png:check_interval=500'
    
videoCommandLine = '/usr/local/bin/ffmpeg -f v4l2 -framerate 25 -video_size 640x480 -i /dev/video%s %s -f mpegts -codec:v mpeg1video -s 640x480 -b:v %dk -bf 0 -muxdelay 0.001 %s http://%s:%s/hello/640/480/' % (deviceAnswer, rotationOption, args.kbps, overlayCommand, server, videoPort)
    
audioCommandLine = '/usr/local/bin/ffmpeg -f alsa -ar 44100 -i hw:1 -ac 2 -f mpegts -codec:a mp2 -b:a 32k -muxdelay 0.001 http://%s:%s/hello/640/480/' % (server, audioPort)

I think it is the problem of video encoding. my url is http://192.168.1.1:8080/?action=stream . So I have getting mpeg encoded frames from this url. I used different ffmpeg command but these are not worked properly. These are the command I used.

    "ffmpeg -i "+URL+" -codec:v libx264 -c:a aac -movflags +faststart "+toFile;
    

    
"ffmepg -i "+URL+" -acodec libfaac -ab 96k -vcodec libx264 -vpre slower -vpre main -level 21 -refs 2 -b 345k -bt 345k -threads 0 -s 640×360 "+toFile;

    So anyone knows how to fix these problem please help me...
