  • ffmpeg single output container with 4 audio channel to AWS IVS

    28 juillet 2021, par Yusufu

    Trying to send 1 video and 4 different audios to AWS IVS in single container. Which container or muxer should I use ?
FLV doesn't support multi audio, matroska doesn't support rtmp I guess link.
3GP and mp4 containers doesn't give me error but neither video showing on IVS

    


    For simple try I am using this command.

    


    ffmpeg -re -stream_loop -1 -i sample.mkv -r 30 -c:v libx264 -pix_fmt yuv420p -profile:v main -preset veryfast -x264opts "nal-hrd=cbr:no-scenecut" -minrate 3000 -maxrate 3000 -g 
60 -c:a aac -ac 2 -ar 44100 -vb 400k -maxrate 400k -minrate 400k -bufsize 800k -movflags frag_keyframe+empty_moov -f mp4 rtmps:someurls


    


    the above command doesn't include multi audio output so just trying to send except the flv format

    


  • Converting AWS Polly Audio Stream with fluent-ffmpeg

    27 juillet 2017, par Joel

    I am trying to convert an audio stream from Amazon AWS Polly in Node.js using fluent-ffmpeg. The documentation says that I can convert a stream, which is what the output of Polly provides, but I am getting an "Invalid input" error.

    polly.synthesizeSpeech(pollyParams, function (err, data) {
    
if (err) {
    
    console.log(err)
    
} else {
    
    console.log('Audio')
    
    console.log(data)
    
    ffmpeg().input(data.AudioStream).inputOptions(['-ac 2', '-codec:a libmp3lame', '-b:a 48k', '-ar 16000']) 
    
}  

    Results in :

    AudioStream : }
    2017-07-27T14:07:09.335Z dd75614c-72d4-11e7-b7cd-5d4425c782fc Error : Invalid input
    at FfmpegCommand.proto.mergeAdd.proto.addInput.proto.input (/var/task/node_modules/fluent-ffmpeg/lib/options/inputs.js:34:15)

    I know the output from Polly is a valid audio stream, because I am able to save it to an S3 bucket. I would prefer to convert the stream before saving to S3, rather than saving it, picking it up from S3, converting it, and then saving it again.

    Thanks for your help !

  • FFmpeg recorded video is dark with Xvfb and chrome headless on Centos 7

    15 juin 2023, par narsy4

    I am trying to do a video recording of headless chrome session on Centos 7 (Amazon EC2 instance) using ffmpeg. I have installed ffmpeg, Xvfb and google chrome on the machine. I started Xvfb on :99, verified the display using xdpyinfo and started chrome. However when I run the ffmpeg cmd to capture the video (no errors in ffmpeg debug logs), the output is dark with a X sign in the centre of video screen. What am I doing wrong here ? Any help is appreciated.

    


    **Xvfb and chrome commands**
Xvfb :99 -screen 0 1920x1080x24 &
export DISPLAY=:99
google-chrome --headless --disable-gpu --no-sandbox --start-maximized --window-size=1920x1080 https://www.google.com



    


    **FFmpeg command**
ffmpeg -video_size 1920x1080 -framerate 30 -f x11grab -i :99 -loglevel debug -pix_fmt yuv420p /tmp/video.mp4
