• Compile ffmpeg with librtmp

  22 avril 2013, par HighFlyingFantasy

  When compiling ffmpeg for OSX, I can simply use the :

  ./configure --enable-librtmp --enable-gpl

  command and get a build that can I/O with an rtmp stream.

  If I attempt to compile for iOS using :

  ./configure \
  
  --disable-ffmpeg \
  
  --disable-ffplay \
  
  --disable-ffprobe \
  
  --disable-ffserver \
  
  --disable-mmx \
  
  --enable-gpl \
  
  --enable-shared \
  
  --enable-librtmp \
  
  --enable-avresample \
  
  --enable-cross-compile \
  
  --enable-pic \
  
  --sysroot="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs /iPhoneOS6.1.sdk" \
  
  --target-os=darwin \
  
  --cc="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/llvm-gcc-4.2" \
  
  --extra-cflags="-arch armv7s -mfpu=neon -miphoneos-version-min=6.1" \
  
  --extra-ldflags="-arch armv7s -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk -miphoneos-version-min=6.1" \
  
  --arch=arm \
  
  --cpu=cortex-a9 \
  
  --prefix=compiled/armv7s 

  it errors out saying ERROR: librtmp cannot be found. Specifically :

      /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/llvm-gcc-4.2 -arch armv7s -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk -miphoneos-version-min=6.1 --sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk -Wl,-dynamic,-search_paths_first -I/usr/local/include -L/usr/local/lib -o /var/folders/4m/8hcrycqx777_ksz6d32nrn_m0000gp/T//ffconf.b2zp97z8 /var/folders/4m/8hcrycqx777_ksz6d32nrn_m0000gp/T//ffconf.VhdlpSe1.o -lrtmp -lz -lssl -lcrypto -lm -lbz2 -lz

  I have already compiled openssl for ios using ios-openssl found on github and librtmp through rtmpdump

• How to run a python code via Django templates ?

  18 novembre 2018, par Iskender Berdiev

  I want to execute code below when the is submitted (project on Django) :

  from os import system, listdir, remove
  
  link = 'https://www.youtube.com/watch?v=ME9yO1KEVoo'
  
  
  
  def download(): ## Downloading a video from YouTube using youtube-dl
  
      system("youtube-dl -o download {}".format(link))
  
  
  
  def convert():  ## Converting downloaded video to mp3 format via ffmpeg.exe(same directory)
  
      listOfFiles = listdir('.')
  
      for i in listOfFiles:
  
          if i.startswith("download"):
  
              name = i
  
              system("ffmpeg -i {} download.mp3".format(name))
  
  
  
  def main():
  
      download()
  
      convert()
  
  
  
  main()

  I have tried to put this code into views.py :

  class download(TemplateView):
  
      def main(request):
  
          if request.method == 'POST':
  
              link = 'https://www.youtube.com/watch?v=ME9yO1KEVoo'
  
              system("youtube-dl -o download {}".format(link))
  
              listOfFiles = listdir('.')
  
              for i in listOfFiles:
  
                  if i.startswith("download"):
  
                      name = i
  
                      system("ffmpeg -i {} download.mp3".format(name))
  
          return redirect ('loader/wait.html')

  urls.py :

  path('wait/', views.download.as_view(), name='wait')

  and the html form which is submitted to run views.download.as_view() :

  <form action="{% url " method="POST">{% csrf_token %}
  
  <input type="submit" value="Yes" />
  
  </form>

• Nginx RTMP/HLS - stream to ffmpeg and output HLS

  20 novembre 2018, par kanazaca

  At this point my solution is working but only as RTMP, i can watch perfectly my stream using the URL :

  rtmp://X.X.X.X:1935/show/name

  But the problem is that my LG Smart Tv which uses WebOS don’t support RTMP and i would really like to play my stream there. The only solution that i can see right now is to use HLS. With HLS all works fine too, but i need to execute my ffmpeg command before open the HLS stream in TV, otherwise it will not create the files necessary to display the stream on my TV.

  So my goal is to serve a stream as HLS without having to trigger the RTMP endpoint or the FFMPEG manually.

  I’m really struggling with this, waste 3 days trying to make it work :(

      add_header 'Access-Control-Expose-Headers' 'Content-Length';

      }
  
  }
  
  
  
  }
  
  rtmp {
  
  server {
  
      listen 1935;

      buflen 5s;
  
  
  
      application show {
  
          live on;
  
  
  
      exec_pull ffmpeg -re -i http://stream-coming.com/$name.ts -c:v libx264 -preset faster -pix_fmt yuv420p -c:a aac -f flv rtmp://localhost/show/$name;
  
  
  
          # Turn on HLS
  
          hls on;
  
          hls_path /mnt/hls/;
  
          hls_fragment 3;
  
          hls_playlist_length 60;
  
          # disable consuming the stream from nginx as rtmp
  
          deny play all;
  
      }
  
  }

  }

  Thanks for your time ;)
