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) {

FFMPEG when live streaming sends a message and exits after some frames were sent
30 octobre 2020, par jstuardowhen doing an streaming with FFMPEG all works perfectly until I get these messages and then, ffmpeg.exe exits :

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)

 Stream #0:1(eng): Video: h264 (Constrained Baseline), yuv420p(progressive), 1920x1080, SAR 1:1 DAR 16:9, 30.30 fps, 14.99 tbr, 1k tbn, 60 tbc (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
