How to make a broadcast in fluent-ffmpeg?
If it's just on the command line, then everything is ok, but when I try to do it through the node, it doesn't work. Who came across, tell me pliz ...
Such is the line:
ffmpeg -f dshow -i video="screen-capture-recorder" -preset ultrafast -vcodec libx264 -tune zerolatency -b 900k -c:a aac -ar 44100 -f flv rtmp://localhost/live/STREAM_NAME
const command = ffmpeg('desktop')
.videoCodec('libx264')
.size('1920x1080')
.flvmeta()
.format('flv')
.inputFPS(25)
.videoBitrate('900k')
.audioCodec('libmp3lame')
.audioBitrate(128)
.addInputOption('-f gdigrab')
// .addInputOption('-f dshow')
// .addInputOption('-i video="screen-capture-recorder"')
.addInputOption('-preset ultrafast')
.addInputOption('-tune zerolatency')
.addInputOption('-c:a aac')
.addInputOption('-ar 44100')
.addOutputOption('rtmp://localhost/live/STREAM_NAME')
.on('codecData', function(data) {
console.log('Input is ' + data.audio + ' audio ' +
'with ' + data.video + ' video');
})
.on('progress', function(progress) {
console.log('Processing: ' + progress.percent + '% done');
})
.on('stderr', function(stderrLine) {
console.log('Stderr output: ' + stderrLine);
})
.on('error', function(err, stdout, stderr) {
console.log('Cannot process video: ' + err.message);
})
.on('end', function(stdout, stderr) {
console.log('Succeeded !');
});
const ffstream = command.pipe();
ffstream.on('data', function(chunk) {
console.log('ffmpeg just wrote ' + chunk.length + ' bytes');
});
Stderr output: [gdigrab @ 00000200acdebd40] Capturing whole desktop as 1920x1080x32 at (0,0)
Stderr output: Option sample_rate not found.
Stderr output:
Cannot process video: ffmpeg exited with code 1: Option sample_rate not found.
