• ffmpeg on windows mobile with C#

  19 septembre 2017, par Riv

  I need to work with FFmpeg for windows mobile with C#, in fact I want build player for .m4b,.m4a files. I know that the TCPMP is exist, but I want to make my own.
  So I want to use .Net, and I have some questions :

  1. If I use some C# FFmpeg wrappers, for example TaoFramework, will it work on windows mobile(in case if I use FFmpeg lib compiled for windows mobile) ?

  2. In FFmpeg wiki I found this

  Once you have compiled, or downloaded,
  the Windows DLLs for FFmpeg, you can
  use .Net Platform Invoke (PI) to
  access the functions in the libraries
  libavformat and libavcodec.
  Link to source...

  But I don’t know how can I use it ? I tried to make it with dll that I had downloaded from http://ffmpeg.arrozcru.org/autobuilds/. Maybe I need to compile ffmpeg by myself for this option ?

  And last question is - what is libavcodec ? When I downloaded shared build, I got avcodec-52.dll, avfilter-1.dll, ffmpeg.exe, but I coudn’t find libavcodec.dll, or it’s just alias ?

• Compile FFmpeg with openssl for macOS

  23 juin 2017, par H. Wilson

  Hi I would like to ask how to compile ffmpeg with openssl for macOS.

  When I type https in ffmpeg to download / encode webstream from the website I always get an error

  "https protocol not found, recompile FFmpeg with openssl, guntls. or securetransport enabled"

  whilst http does work (some websites didn’t allow http as I got an error "HTTP error 403 Forbidden though)

  https://trac.ffmpeg.org/wiki/CompilationGuide/MacOSX

  I have read the link above but I am unsure about the process as I don’t use homebrew to install ffmpeg but built myself.

  I am the very beginner using ffmpeg and any help would be appreciated..
  I hope somebody could show me its process to compile ffmpeg with openssl.

  For further advice, I am wondering if the function of ffmpeg I built myself is same as the static one here : ttps ://ffmpeg.zeranoe.com/builds/

  I built ffmpeg for mac by this website : http://ericholsinger.com/install-ffmpeg-on-a-mac

  Thanks in advance
