HackWebRTC

Let's hack into WebRTC :)

Use WebRTC static library

• https://blog.piasy.com/2017/09/03/Use-WebRTC-Static-Library/
• Copy header files:

# CP='gcp' # mac
# CP='cp'  # linux

find api audio base call common_audio common_video logging media \
modules ortc p2p pc rtc_base rtc_tools sdk stats system_wrappers \
video -name "*.h" \
-exec $CP --parents '{}' <target dir> ';'
find . -maxdepth 1 -name "*.h" -exec $CP --parents '{}' <target dir> ';'

Tips:

• Due to the file size limit of GitHub, I ignore libwebrtc.a, please extract it and put it under app/libs/webrtc/lib/armeabi-v7a/ before building.
• It's important to disable RTTI in your project setting if you want to use WebRTC static library, otherwise linker will fail with something like undefined reference to 'typeinfo for rtc::MessageHandler'.
• You also need add some definitions in your project, refer to here and here.
  • Android: WEBRTC_POSIX, WEBRTC_LINUX, WEBRTC_ANDROID
  • iOS: WEBRTC_POSIX, WEBRTC_MAC, WEBRTC_IOS

WebRTC src extractor

python webrtc_src_extractor.py <repo dir> <dst dir> <wanted src file, seperated by space>

If you only want use a small part of WebRTC code, this script could help you find all related sources and headers, and copy them into dst dir. Note that it's just a best effort script, you may still need copy several sources manually.
