FFMPEG when live streaming sends a message and exits after some frames were sent

Normally, the messages I received are similar to this :


frame= 1196 fps=3.4 q=13.0 size= 2692kB time=00:01:20.08 bitrate= 275.4kbits/s speed=0.227x 


Which are the expected messages. Sometimes, I received this message, but this does not cause ffmpeg.exe to exit :


Input #0, matroska,webm, from 'pipe:':

 Metadata:

 encoder : Chrome

 Duration: N/A, start: 0.000000, bitrate: N/A

 Stream #0:0(eng): Audio: opus, 48000 Hz, mono, fltp (default)

What may be happening ? maybe it is a problem of the RTMP server ? or something is wrong with FFMPEG ?


This version of FFMPEG.EXE is for windows. The programming language is C# from where I am launching FFMPEG.EXE process.


As I told, this happens after several frames sent to the server. Only once, this problem occured after a few frames sent. That is why I suspect that the RTMP server is the problem.


EDIT : This is the command :


FFMPEG -i - -c:v libx264 -preset ultrafast -tune zerolatency -max_muxing_queue_size 1000 -bufsize 5000 -r 15 -g 30 -keyint_min 30 -x264opts keyint=30 -crf 25 -pix_fmt yuv420p -profile:v baseline -level 3 -c:a aac -b:a 22k -ar 22050 -f flv rtmp://rtmp.xxxx.yyyy

couldn't populate thumbnail on client side
8 novembre 2020, par Lokirouter.post("/thumbnail",(req,res)=>{

 let thumbsFilePath="";
 let fileDuration="";



 ffmpeg.ffprobe(req.body.filePath, function(err,metadata){
 console.dir(metadata);
 console.log('METADATA==>'+metadata);
 console.log(metadata.format.duration);

 fileDuration=metadata.format.duration;

 })

 
 ffmpeg(req.body.filePath)
 .on('filenames', function(filenames) {
 console.log('Will generate ' + filenames.join(','))
 thumbsFilePath="uploads/thumbnails/"+ filenames[0];
 })
 .on('end', function() {
 console.log('Screenshots taken');
 console.log('FILEPATH===>'+thumbsFilePath);
 console.log('FILEDURATION===>'+fileDuration);
 return res.json({success: true, thumbsFilePath , fileDuration})
 })
 .screenshots({
 // Will take screens at 20%, 40%, 60% and 80% of the video
 count: 3,
 folder: 'uploads/thumbnails/',

 // %b input basename ( filename w/o extension )

 });
})


the screenshots are saved perfectly and their path is also received to the client-side from
thumbsFilePathbut I cant populate it in the client-side page(react).. idk what I am doing wrong here.

usestate

const [FilePath, setFilePath]= useState('');
 const [Duration, setDuration] = useState('');
 const [Thumbnail, setThumbnail] = useState('');


here is an error when I try to populate img




const onDrop=(files)=>{
 let formData= new FormData();
 let config={
 header:{'content-type':'multipart/form-data'}
 }
 
 formData.append("file",files[0])
 Axios.post('http://localhost:5000/api/video/uploadFiles',formData,config)
 .then(response=>{
 console.log(response);
 if(response.data.success){
 console.log('FILEPATH==>'+response.data.filePath);
 console.log('filename==>'+response.data.fileName);
 let variable={
 filePath:response.data.filePath,
 fileName:response.data.fileName
 }
 setFilePath(response.data.filePath);
 Axios.post('http://localhost:5000/api/video/thumbnail',variable)
 .then(response=>{
 if(response.data.success){
 setDuration(response.data.fileDuration)
 setThumbnail(response.data.thumbsFilePath)
 }else{
