• Can I Config FFMEG-2.4.3 to use in android windows 64 ?

  13 novembre 2014, par Ngo Ky

  I want to build ffmpeg-2.4.3 (lastest c lib) to use it on android for managing video.
  my OS is windows 7 Utimate x64
  cywin64 in directory : C :/cywin64/ have make installed.
  NDK in directory : D :\solfware\Programming\android-ndk-r10c

  i follow toturial form : http://www.roman10.net/how-to-build-ffmpeg-for-android/comment-page-1/
  my project struture like :

  

  i create build_android.sh like roman10 as following code :

  # ARMv7+Neon (Cortex-A8)
  
  # Customizing:
  
  # 1. Feel free to change ./configure parameters for more features
  
  # 2. To adapt other ARM variants
  
  # set $CPU and $OPTIMIZE_CFLAGS 
  
  # call build_one

  i have set my path like above
  I built it in Eclipse Everything is ok. but when i ran it in Android it crashed Unfortunately.
  I found the errors in Logcat monitor :

  E/AndroidRuntime(1931) : java.lang.UnsatisfiedLinkError : Couldn’t load avcodec-55 from loader dalvik.system.PathClassLoader[DexPathList [1]] : findLibrary returned null

  E/AndroidRuntime(1931) : at java.lang.Runtime.loadLibrary(Runtime.java:358)

  In my activity i just call add Library from C preference like :

  static {
  
          //System.loadLibrary("avutil-52");
  
          System.loadLibrary("avcodec-55");
  
          System.loadLibrary("avformat-55");
  
          System.loadLibrary("swscale-2");
  
          System.loadLibrary("tutorial02");
  
      }

  i check in DDMS in app-lib there is no existing Library in there.

  The question is : Can i can compile the ffmpeg on windows ?
  if ok. how can i config build_android.sh to point to Android $PREBUILT

  PLATFORM=$NDK/platforms/android-8/arch-arm/
  
      PREBUILT=$NDK/prebuilt/windows-x86_64
  
      function build_one
  
      {
  
      ./configure --target-os=linux \
  
          --prefix=$PREFIX \
  
          --enable-cross-compile \
  
          --extra-libs="-lgcc" \
  
          --arch=arm \
  
          --cc=$PREBUILT/bin/arm-linux-androideabi-gcc \
  
          --cross-prefix=$PREBUILT/bin/arm-linux-androideabi- \
  
          --nm=$PREBUILT/bin/arm-linux-androideabi-nm \
  
          --sysroot=$PLATFORM \
  
          --extra-cflags=" -O3 -fpic -DANDROID -DHAVE_SYS_UIO_H=1 -Dipv6mr_interface=ipv6mr_ifindex -fasm -Wno-psabi -fno-short-enums -fno-strict-aliasing -finline-limit=300 $OPTIMIZE_CFLAGS " \
  
          --disable-shared \

  i found that in $NDK/prebuilt/windows-x86_64/bin did not exist arm-linux-androideabi-gcc\
  How can i config to be suitable to run on windows ?

  Thank in advanced

• lavf : Use wchar functions for filenames on windows for mkdir/rmdir/rename/unlink

  17 novembre 2014, par Martin Storsjö

  lavf : Use wchar functions for filenames on windows for mkdir/rmdir/rename/unlink
  This makes sure that the internal utf8 path names are handled
  
  properly - the normal file handling functions assume path names
  
  are in the native codepage, which isn’t utf8.
  This assumes that the tools outside of lavf don’t use the mkdir
  
  definition. (The tools don’t do the same reading of command line
  
  parameters as wchar either - they probably won’t handle all possible
  
  unicode file parameters properly, but at least work more predictably
  
  if no utf8/wchar conversion is involved.)
  This is moved further down in os_support.h, since windows.h shouldn’t
  
  be included before winsock2.h, while io.h needs to be included before
  
  the manual defines for lseek functions.

• How do I install stream-m on my vps server using putty for windows

  19 décembre 2014, par They Went Viral

  when i logged into my vps server using the plesk control panel i see httpdocs in the root when using putty i entered an ls command and i only see

  @vps : # ls
  ffmpeg parallels parallels_installer plesk-installer.sh univac.webm

  wonder why this is why dont i see the same files as in te control panel ??!

  the problem is i am trying to run this https://github.com/vbence/stream-m on the server
  the read me says

  RUNNING THE SERVER

  java -jar stream-m.jar

  Before running the server you should edit the sample config file (change password and choose a stream name). So you will end up with something like :

  java -jar stream-m.jar server.properties

  but im getting an error that says

  @vps : # java -jar stream-m.jar server.properties
  Error : Unable to access jarfile stream-m.jar

  Now i do have ffmpeg installed as per putty but when logged into the control panel i don’t see that either what am i doing wrong ?
