• Use ffmpeg to stream live content to azure media services

  19 mars 2018, par Dadicool

  I’ve been trying to stream content to azure media services using ffmpeg as it’s one of the options described here : http://azure.microsoft.com/blog/2014/09/18/azure-media-services-rtmp-support-and-live-encoders/

  My command is :

  ffmpeg -v verbose -i 300.mp4 -strict -2 -c:a aac -b:a 128k -ar 44100 -r 30 -g 60 -keyint_min 60 -b:v 400000 -c:v libx264 -preset medium -bufsize 400k -maxrate 400k -f flv rtmp://nessma-****.channel.mediaservices.windows.net:1935/live/584c99f5c47f424d9e83ac95364331e7

  I have made sure that the streaming endpoint has one active streaming unit, I also made sure that the channel is actually Ready and I even get it to start streaming (which makes a PublishURL available).

  When I execute the ffmpeg command to start streaming, I keep getting the following error :

  The Azure blog post clearly states that this should be possible but I can’t find a working example anywhere.

  Environment :

  • MacOS Maverick
  • FFMPEG installed from official build
  • 300.mp4 : 1080p trailer of the latest 300 movie

• Live streaming .webm file with ffmpeg and nginx

  9 décembre 2017, par seekahead

  Hi I am new to ffmpeg and I need some help with live streaming of .webm file which is still being written into. I have a .webm file containing only video in vp9 codecwhich needs to be live streamed (preferably without transcoding and streamed using DASH`. I have compiled nginx along with nginx-ts-module from (https://github.com/arut/nginx-ts-module#features) with the following configuration

  nginx version: nginx/1.12.1
  
  built by gcc 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04.3) 
  
  built with OpenSSL 1.0.1f 6 Jan 2014
  
  TLS SNI support enabled
  
  configure arguments: --with-cc-opt='-g -O2 -fPIE -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security -fPIC -D_FORTIFY_SOURCE=2' --with-ld-opt='-Wl,-Bsymbolic-functions -fPIE -pie -Wl,-z,relro -Wl,-z,now -fPIC' --prefix=/usr/share/nginx --conf-path=/etc/nginx/nginx.conf --http-log-path=/var/log/nginx/access.log --error-log-path=/var/log/nginx/error.log --lock-path=/var/lock/nginx.lock --pid-path=/run/nginx.pid --modules-path=/usr/lib/nginx/modules --http-client-body-temp-path=/var/lib/nginx/body --http-fastcgi-temp-path=/var/lib/nginx/fastcgi --http-proxy-temp-path=/var/lib/nginx/proxy --http-scgi-temp-path=/var/lib/nginx/scgi --http-uwsgi-temp-path=/var/lib/nginx/uwsgi --with-debug --with-pcre-jit --with-http_ssl_module --with-http_stub_status_module --with-http_realip_module --with-http_auth_request_module --with-http_v2_module --with-http_dav_module --with-http_slice_module --with-threads --with-http_addition_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_sub_module --with-stream=dynamic --with-stream_ssl_module --with-stream_ssl_preread_module --with-mail=dynamic --with-mail_ssl_module --add-dynamic-module=/home/ubuntu/NGINX/nginx-ts-module-master

  The mediafile has the following properties(obtained with mediainfo) :

  General
  
  Complete name                            : video_4_1_Admin_0.webm

  I am trying to stream the file with the following

  ffmpeg -re -i video_4_1_Admin_0.webm -bsf:v vp9_superframe -c copy -f webm_chunk  http://127.0.0.1:8000/publish/sintel

  And I am getting the following error

  Input #0, matroska,webm, from 'video_4_1_Admin_0.webm':
  
    Metadata:
  
      encoder         : libwebm-0.2.1.0

  Output #0, webm_chunk, to 'http://127.0.0.1:8000/publish/sintel':
  
  Output file #0 does not contain any stream

  I am not sure what are the exact options to be passed to ffmpeg so that it creates the .mpd and needed chunks which will allow me to LiveStream the media, I tried replacing the options given in the example (https://github.com/arut/nginx-ts-module#features) with what seems like vp9 equivalent., but, I am not sure. Can someone help me out here ? Thanks in advance

• FFMPEG recording from live m3u8 to a .ts file

  6 juillet 2016, par Riste Markovski

  I am trying to record from a live HLS to save a file.

  However sometimes the HLS stutters or cuts for a short amount of time probably even less than seconds and interrupts my recording.

  The command and FFMPEG build :
