Build PJSIP with openh264

Step 1. Download openh264

1. Unzip file and move to /User/me
2. Create new folder: android in openh264 folder
3. Modified OpenH264’s Makefile by setting PREFIX=android
4. And
   make OS=android NDKROOT=<path-to-ndk> TARGET=android-19 APP_ABI=armeabi ARCH=arm make OS=android NDKROOT=<path-to-ndk> TARGET=android-19 APP_ABI=armeabi ARCH=arm clean make install OS=android NDKROOT=<path-to-ndk> TARGET=android-19 APP_ABI=armeabi ARCH=arm

Step 2. Create config_site.h

1. Download pjsip from repository
2. Create config_site.h
3. Go to /path/to/your/pjsip/dir/pjlib/include/pj
4. Copy config_site_sample.h
5. Rename copy file to config_site.h
6. Add:
   #define PJ_CONFIG_ANDROID 1 #include <pj/config_site_sample.h> #define PJMEDIA_HAS_VIDEO 1 #define PJMEDIA_HAS_OPENH264_CODEC 1
   
   

Step 3. Build Preparation

cd /path/to/your/pjsip/dir
export ANDROID_NDK_ROOT=/path_to_android_ndk_dir 
APP_PLATFORM=android-19 ./configure-android --with-openh264=<path-to-openh264>/android 
make dep && make clean && make

Note: This will build armeabi target, to build for other targets:

TARGET_ABI=armeabi-v7a ./configure-android --use-ndk-cflags

Step 4. Video Support

Copy all library .so files into your Android application project directory, for example:

cp /Users/me/openh264/android/*.so /Users/me/pjproject-2.0/pjsip-apps/src/swig/java/android/libs/armeabi

Step 5. Build libpjsua2.so and running sample application

cd /path/to/your/pjsip/dir
cd pjsip-apps/src/swig
make clean && make

This step should produce:

• native library libpjsua2.so in pjsip-apps/src/swig/java/android/app/src/main/jniLibs/armeabi
• Open pjsua2 app project in Android Studio, it is located in pjsip-apps/src/swig/java/android

Step 6. Run it
