• Compile static FFmpeg with openssl

  26 janvier 2016, par Nisker

  I am trying to compile FFmpeg static (one binary) using

  ./configure --pkg-config-flags="--static" --enable-gpl --enable-version3 --enable-libfdk_aac --enable-libmp3lame --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-nonfree --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libxvid --enable-postproc --enable-avfilter --enable-static --disable-shared --enable-pthreads --enable-openssl --extra-libs='-static' --extra-cflags=--static  

  But I am getting

  ERROR: openssl not found

  I have openssl installed, have tried with the rpm and also compiled openssl with static but dont have luck, here is part of the config.log

  BEGIN /tmp/ffconf.2NFtoMnY.c

  Anyone have a clue ?

• Electron spawn ffmpeg ENOENT

  3 août 2022, par Menno

  I am building an Electron app to display a rtsp stream.

  


  When using the locally installed ffmpeg (/usr/local/bin/ffmpeg) on the (MacOS) Desktop all works well. Since the app needs to be distributed to different desktops and i don't want to be dependent on local installation of ffmpeg i am trying to bundle ffmpeg / fluent-ffmpeg but somehow i am missing the clue and all my attempts end up in Uncaught Error : spawn ffmpeg ENOENT

  


  I am a complete newby to Electron and nodejs and am sure i am missing a very basic concept here, somebody willing to help me out ?

  


  This is my code :

  


  main.js

  


  const { app, BrowserWindow } = require('electron');
const { ipcMain } = require('electron');
const path = require('path');

const createWindow = () => {
  const win = new BrowserWindow({
    width: 800,
    height: 600,
    webPreferences: {
      preload: path.join(__dirname, 'preload.js'),
    },
  });
    
  win.loadFile('index.html');
};

app.whenReady().then(() => {
  createWindow();

  app.on('activate', () => {
    if (BrowserWindow.getAllWindows().length === 0) {
      createWindow();
    }
  });
});

app.on('window-all-closed', () => {
  if (process.platform !== 'darwin') {
    app.quit();
  }
});

const ffmpeg = require("fluent-ffmpeg");
ffmpeg.setFfmpegPath(ffmpegPath);

var stream = require('node-rtsp-stream')

• ffmpeg to kurento rtp stream choppy video issue

  29 juillet 2020, par ahmetsarias

  I use ffmpeg to make an rtp stream to kurento media server and then send it to browsers via webrtc.

  


  ffmpeg (h264 RTP) -> Kurento -> (h264 WebRTC) Browser

  


  I'm capturing virtual xorg display.
This is my ffmpeg command :

  


  ffmpeg -y -v info -fflags +genpts -f x11grab -draw_mouse 0 -r 25 -s 1280x720 -thread_queue_size 4096 -i :0.0+0,0 -an -c:v libx264 -preset veryfast -crf 25 -g 50 -pix_fmt yuv420p -maxrate 2976k -bufsize 5952k -ssrc 112233 -payload_type 103 -tune zerolatency -f rtp rtp://172.16.1.115:40258

  


  This is my fake sdp offer used in negotiation with kurento RtpEndpoint

  


  v=0
o=- 0 0 IN IP4 127.0.0.1
s=Stream
c=IN IP4 127.0.0.1
t=0 0
m=video 9 RTP/AVP 103
a=rtpmap:103 H264/90000
a=fmtp:103 packetization-mode=1
a=sendonly
a=direction:active
a=ssrc:112233 cname:user@example.com 


  


  Here is the problem :

  


  Some I-frames are choppy on bottom half slice of the frame while others have no problem.

  


  It is sometimes corrected when another I-frame has arrived, but mostly choppy.

  


  When choppiness happened, Kms log says :

  


  


  kmsutils kmsutils.c:483:gap_detection_probe:kmsagnosticbin2-108:sink Stream gap detected, timestamp : 0:51:22.574766908, duration : 0:00:00.000008237

  


  


  Normal stream (No choppy at all)

  


  

  


  Choppy stream

  


  

  


  When it is corrected with an I-Frame (Sometimes it happens)

  


  

  


  I have no clue about what could lead the issue.

  


  Things that I tried to solve the problem.

  


  

  • Adding ?pkt_size=1000 (1100,900,1200. Since the mtu in kurento is 1200 default)

  


  • Changing -crf to different values in between 18-35

  


  • Changing -preset between medium and ultrafast

  


  • Changing framerate

  


  • Changing gop length (When i lower the gop length -More I-Frames- choppiness become shorter in duration but more frequent)

  


  • When I disable sliced-threads, there is no issue with bottom side but whole screen freezes in same scenario

  


  


  Any help would be appreciated. Thanks.
