• FFMPEG hls m3u8 live stream

  4 juillet 2018, par Num Nuts

  I’m trying to download a m3u8 live stream but it requires cookies to access the files. Can anyone correct my command line ? Thanks.

  Use -h to get full help or, even better, run ’man ffmpeg’

• Trouble with hardware-assisted encoding/decoding via FFmpeg on Azure GPU vm's (ubuntu 16.04)

  3 mai 2017, par user3776020

  I am trying to use NVIDIA hardware acceleration with FFmpeg/libav, but can’t get it to work correctly on Azure vm’s running Ubuntu 16.04. For a sample case, I am trying to do a simple decoding of an h264 video into a raw YUV file (as detailed here : https:// developer.nvidia.com/ffmpeg).

  So far, I’ve tried it on NC-6, NC-12, and NV-6 machines (in different regions). In each of these instances, it would take about 30-45 seconds to process a single video frame. As a comparison, I also tried it on a P2.xlarge vm on AWS (which has very similar specs to the NC-6), which was able to process about 3000 frames in about 5 seconds. Has anyone else run into this issue with Azure machines, or has any idea why this would be the case ?

  Here are the commands I used to install the necessary drivers/libraries/etc (I also verified that each machine as the same NVIDIA driver version installed - 375.51) :

  CUDA_REPO_PKG=cuda-repo-ubuntu1604_8.0.61-1_amd64.deb

  wget -O /tmp/$CUDA_REPO_PKG
  http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1604/x86_64/$CUDA_REPO_PKG

  sudo dpkg -i /tmp/$CUDA_REPO_PKG

  sudo apt-get update

  sudo apt-get install -y cuda-drivers

  sudo apt-get install -y cuda

  sudo apt-get install -y nvidia-cuda-toolkit

  [reboot]

  sudo apt-get update

  sudo apt-get upgrade -y

  sudo apt-get dist-upgrade -y

  [reboot]

  git clone https://github.com/FFmpeg/FFmpeg.git

  [download the latest video codec SDK from NVIDIA at : https://
  developer.nvidia.com/designworks/video_codec_sdk/downloads/v7.1]

  [unzipped codec, and copy header files from
  /Video_Codec_SDK_7.1.9/Samples/common/inc/ into /usr/include/]

  cd /FFmpeg

  ./configure —enable-nonfree —disable-shared —enable-nvenc
  —enable-cuda —enable-cuvid —enable-libnpp —extra-cflags=-Ilocal/include —extra-cflags=-I../nv_sdk —extra-ldflags=-L../nv_sdk

  sudo make && sudo make install

  For the FFmpeg command that I used to decode a sample movie file, I used the following :

  sudo ffmpeg -vsync 0 -c:v h264_cuvid -i sample_vid.mp4 -f rawvideo outputvid.yuv

• Issues executing ffmpeg on windows

  4 avril 2017, par Somename

  Installed ffmpeg. Added the PATH in system Environment Variables and can execute ffmpeg from anywhere in the cmd. Installed fluent-ffmpeg. Below is my script :

  var express = require('express');
  
  var bodyParser = require('body-parser');
  
  var app = express();
  
  var ffmpeg = require('fluent-ffmpeg');  
  
  
  
  var proc = new ffmpeg({ source: 'myfile.gif' })
  
    .withAspect('4:3')
  
    .withSize('640x480')
  
    .applyAutopadding(true, 'white')
  
    .saveToFile('myfile.avi', function(stdout, stderr) {
  
      console.log('file has been converted succesfully');
  
    });
  
  
  
  app.listen(3000, function() {  
  
      console.log("Server Running on 3000");
  
  });

  Getting error :
  

  

  Please help.
