• FFMPEG multi livestream - recorded stream send to different services like YT and Twitch at different time (on different button clicks )

  4 octobre 2022, par Ganesh

  Trying for the last 10 days and still no success, I am creating a python application that will accept the URL and visit that URL using chromium, capture that screen and send that real-time screen recording to different live stream acceptors as youtube live, twitch Twitter, Facebook live or some other sources and many of these could be multiple.

  


  There are two challenges (both challenges depend on a user action like different button clicks) -

  


  

  • The time of starting the Livestream we know only one Livestream acceptor and other acceptors could be sent via another API at any time or may not be sent on the whole live stream.

  


  • Any of the streams could be stopped at any moment including the first one which started the original live streaming service

  


  


  To Solve these challenges I am trying the following process (i took mp4 as a source for simplifying)

  


  

  • create a stream and store it into PIPE.stdout

  


  


  ffmpeg_Command_get_stream = 'ffmpeg -re -i test.mp4 -f flv pipe:1'
ffmpeg_Command_get_stream=ffmpeg_Command_get_stream.split()
pipe = sp.Popen(ffmpeg_Command_get_stream,
            stdout=sp.PIPE,
            stderr=sp.PIPE,
            bufsize=8000000,
            shell=True,
            universal_newlines=True
            )
out,err = pipe.communicate()


  


  


  • and send that stream with the help of FFMPEG to the Livestream acceptor with the click of the youtube Livestream button

    


    ffmpeg_Command_send_stream = ['ffmpeg','-i',pipe.stdout,'-f','flv',RTMPURL_YOUTUBE]

    


  


  


  Update Trying to Explain it a little more :

  


  step 1 - I need a real-time stream from the first command, so I used -re in FFMPEG

  


  step 2 - Use above stream as an input for other command and send that as an output as a Livestream to youtube (or twitch/Facebook), But the second step would happen only when the user click on the button "YT LiveStream", Here the tricky thing is there are multiple buttons (YT LiveStream, Twitch LiveStream, Facebook LiveStream) and user can click any time on any of button, also can click on all button one by one.

  


  

  


  sorry for bad explaination

  


  what I am doing wrong ? , Is this Possible ? or need to go with another process,

  


  any help would be greatly appreciated

  


• x264 Building error - Android

  21 avril 2016, par Jay Parikh

  I am using this repository to build ffmpeg static library which includes x264,libpng and others, please
  visit this link https://github.com/writingminds/ffmpeg-android

  i am using windows 7 as host and ubuntu 15.10 (_64) as guest os using VMware Workstation 12
  and
  Android-ndk-r11b-linux-x86_64

  i do have Prebuilt libraries , but now i want it without PIE support

  i am getting this error in config.log in x264 folder while building
  through

  ./android_build.sh

  here is the log :

  x264 configure script
  
  Command line options: "--cross-prefix=/mnt/hgfs/uShare/ffmpeg-android/toolchain-android/bin/arm-linux

  ushare is my shared folder between windows and ubuntu

  I have spend almost a week ,trying to solve every error i get.
  these errors are like never ending , 1 solution give 10 more errors
  i have researched a LOT for this library

  thanks a lot in advance.

  Also i thought that x264 library might have poroblem ,so i tried to disable it
  but next library "libpng" also had Same log Error

  i think problem is in Input/output error (obviously)
  this line in log kind of confuses me (those /../../)

  /mnt/hgfs/uShare/ffmpeg-android/toolchain-android/bin/../lib/gcc/arm-linux-androideabi/4.9/../../../../arm-linux-androideabi/bin/ld : fatal error :

  its like two folder overlaping address...

  thanks a lot in advance.
  please don’t go harsh on me ,its my first time,all thanks to this thing...
