Files content

scripts to copy over folders and files from upstream WebRTC project for APM and its dependencies.
Copied files from upstream WebRTC project. For example: common_audio, modules, rtc_base and system_wrappers.
webrtc_apm.cc/h C wrappers to access APM functions.
common-mk based makefiles to build shared library libwebrtc_apm.so

Update

To update this package to latest upstream WebRC:

Run ./script/sync-apm.sh path/to/webrtc-checkout/src .
emerge webrtc-apm to see if anything breaks.
If emerge success, then we're good.
Otherwise look into the emerge failure, and then possibly:
- Update sync-apm.sh to copy more files if upstream directory structure changes.
- Update makefiles if upstream build files has changed.
- Update webrtc-apm ebuild file if dependencies changed.
