This directory contains an app for measuring the total delay from the native
|
||
|
|
OpenSL implementation. Note that it just loops audio back from mic to speakers.
|
||
|
|
|
||
|
|
Prerequisites:
|
||
|
|
- Make sure gclient is checking out tools necessary to target Android: your
|
||
|
|
.gclient file should contain a line like:
|
||
|
|
target_os = ['android']
|
||
|
|
Make sure to re-run gclient sync after adding this to download the tools.
|
||
|
|
- Env vars need to be set up to target Android; easiest way to do this is to run
|
||
|
|
(from the libjingle trunk directory):
|
||
|
|
. ./build/android/envsetup.sh
|
||
|
|
Note that this clobbers any previously-set $GYP_DEFINES so it must be done
|
||
|
|
before the next item.
|
||
|
|
- Set up webrtc-related GYP variables:
|
||
|
|
export GYP_DEFINES="$GYP_DEFINES java_home=</path/to/JDK>
|
||
|
|
enable_android_opensl=1"
|
||
|
|
- Finally, run "gclient runhooks" to generate Android-targeting .ninja files.
|
||
|
|
|
||
|
|
Example of building & using the app:
|
||
|
|
|
||
|
|
cd <path/to/repository>/trunk
|
||
|
|
ninja -C out/Debug OpenSlDemo
|
||
|
|
adb install -r out/Debug/OpenSlDemo-debug.apk
