• ffmpeg compilation issue on Windows phone 8.1

  24 février 2017, par Mirko Puliafito

  Taking a look at Build ffmpeg for windows phone 8
  I was able to compile ffmpeg on Windows phone 8using these steps :

  My configuration

  OS : Windows 8.1 VS : Ultimate 2013 Update 3 (If armasm fails, msvcdis110.dll missing download it from dllsearch ) Mingw (be sure that "link" and "cl" commands point to MS "link" and "cl") FFmpeg 2.1.5

  Follow prerequisites listed here : https://ffmpeg.org/platform.html#Microsoft-Visual-C_002b_002b-or-Intel-C_002b_002b-Compiler-for-Windows

  -) Download c99toc89 : https://github.com/libav/c99-to-c89/downloads/. Be sure all files from c99toc89 are in Mingw PATH (copy in /bin)

  -) FFMPEG requires stdint.h and inttypes.h headers standardized as a part of C99. Unfortunately, Visual Studio does not include these files. Fortunately, there is a project that fixes this issue. Download the latest version and unpack it to Visual Studio includes (C :\Program Files (x86)\Microsoft Visual Studio 11.0\VC\include).

  -) Launch cmd and "c :\Program Files (x86)\Microsoft Visual Studio 12.0\VC\vcvarsall.bat x86_arm" and then msys

  -) configure :

  ./configure --toolchain=msvc \
  
  --disable-programs \
  
  --disable-network \
  
  --disable-protocols \
  
  --extra-cflags="-D_ARM_WINAPI_PARTITION_DESKTOP_SDK_AVAILABLE -D_M_ARM -D_WINAPI_FAMILY=WINAPIFAMILY_APP" \
  
  --enable-cross-compile \
  
  --target-os=win32 \
  
  --arch=arm \
  
  --as=armasm \
  
  --cpu=armv7 \
  
  --disable-yasm \
  
  --extra-ldflags="-MACHINE:ARM" \
  
  --disable-dxva2 \
  
  --disable-asm \
  
  --disable-doc

  I was able to get .a static libs but I wasn’t able to generate an app using it. I have problems while linking for kernel32.lib and libcmt.lib misses.

  Anyone ?

• iPhone - FFMPEG/VLC audio stream for iOS

  24 avril 2013, par Siriss

  I am trying to write an app for a school project that will play a video stream of the lab. They use Foscam cameras, and from what I understand they only stream audio in FFMPEG and VLC (a wrapper of FFMPEG and others, correct ?). I can play the video stream in a UIWebView just fine, but I can't figure out how to get audio to work. I have read a bunch of post on here about the different audio stream options, but none support this format. I have also looked into VLCKit, but that seems to only work in OS X, not iOS.

  Is there a Framework, or Kit that can stream audio from a VLC/FFMPEG file, or does someone know of a better way to get audio from a Foscam ?
