• Android Get only Audio Stream of Online Video ?

  19 avril 2014, par user1575044

  I am beginner in Android, basically I want to get only audio stream of an online streaming video, so that I don't have to download video just download audio part of video only as an mp3 file(saving lot of data if you only need it as an mp3 file). I researched and got to know it can be done maybe using ffmpeg. Can someone guide me in this, some tutorials links or sample code would be beneficial.

  Thank You !!

• Video streaming with ipCamera in iphone

  6 juillet 2013, par user1120998

  I am developing app for the connecting ip camera and get stream. I don't know how to convert stream into video. I have analysed, and then i tried FFMPEG library. But i did not get correct url for ios with FFMPEG. Can you suggest the guide for implementation.

  Now i am integrating ffmpeg, when i integrated i got the error when opening avformat_find_stream_info() function. I used the increase or less the value of pFormatCtx->max_analyze_duration. But no solution for this.

  [mjpeg @ 0x8b85000] max_analyze_duration 1000 reached at 40000
  [mjpeg @ 0x8b85000] Estimating duration from bitrate, this may be inaccurate

  Pls help how to solve this.

• Can't call FFMPEG from CMD after installing chocolatey+ffmpeg on windows docker container

  19 novembre 2022, par Adil Abdul Rahman

  I have a C# code that is dependent on FFMPEG via CMD/powershell. I am trying to run CLI ffmpeg via a C# code in a windows container with sdk:6.0-windowsservercore-ltsc2022. I found this guide(use 12ft.io to bypass paywall) that says to install chocolatey and then install ffmpeg through that like so :

  


  USER ContainerAdministrator
EXPOSE 3389/tcp


RUN powershell.exe \
  Set-ExecutionPolicy Bypass -Scope Process -Force; \
  iwr -Uri 'https://community.chocolatey.org/install.ps1' -UseBasicParsing -OutFile $home/choco_install.ps1; \
  powershell $home/choco_install.ps1; \
  del $home/choco_install.ps1; \
  choco; \
  exit 0;
  
RUN powershell.exe \
  powershell choco install chocolatey-compatibility.extension -y --force; \
  powershell choco install chocolatey-core.extension -y --force; \
  powershell choco install ffmpeg-full -y --force; \
  ffmpeg; \
  exit 0;


  


  ( I am using this guide for C# dockerfile )

  


  And my C# Code :

  


  string command = $"/C ffmpeg -i \"{VideoUri}\" -vn -ac 1 {outputName}.mp3";
Process.Start("cmd.exe", command).WaitForExit();


  


  But I am running into some trouble. My C# code throws this error :

  


  'ffmpeg' is not recognized as an internal or external command, operable program or batch file.

  


  I have tried calling FFMPEG from the dockerfile to test if it has installed but it just returns this :

  


  Step 5/17 : RUN powershell.exe   powershell choco install chocolatey-compatibility.extension -y --force;   powershell choco install chocolatey-core.extension -y --force;   powershell choco install ffmpeg-full -y --force;   ffmpeg;   exit 0;
