This is a reland of commit 937a59268e2ae56a58f648fba827444f7beb4466 Check if codec requested in createEncoder/Decoder is supported and return null if not. Original change's description: > Call native codec factories from Android ones. > > Android video codec factories are expected to be synchronised with the native ones in terms on supported codecs. But before this change there were differences: > > 1. Native decoder factory keeps AV1 support behind RTC_DAV1D_IN_INTERNAL_DECODER_FACTORY while Android decoder factory advertises AV1 unconditionally; > > 2. Native encoder factory advertises AV1 if RTC_USE_LIBAOM_AV1_ENCODER is enabled while Android encoder factory never advertises AV1. > > This CL synchronises the codecs set in Android factories with that of native factories by calling native factories from Android ones. > > Bug: webrtc:13573, b/257272020 > Change-Id: I99d801eda0c5f3400bac222b9b08d719f1a6ed72 > Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/282240 > Reviewed-by: Rasmus Brandt <brandtr@webrtc.org> > Commit-Queue: Sergey Silkin <ssilkin@webrtc.org> > Reviewed-by: Xavier Lepaul <xalep@webrtc.org> > Cr-Commit-Position: refs/heads/main@{#38583} Bug: webrtc:13573, b/257272020 Change-Id: Ida7bb9a2954b836a07ad560de29c1f8088264b77 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/282802 Reviewed-by: Xavier Lepaul <xalep@webrtc.org> Commit-Queue: Sergey Silkin <ssilkin@webrtc.org> Cr-Commit-Position: refs/heads/main@{#38607}
This directory holds a Java implementation of the webrtc::PeerConnection API, as
well as the JNI glue C++ code that lets the Java implementation reuse the C++
implementation of the same API.
To build the Java API and related tests, make sure you have a WebRTC checkout
with Android specific parts. This can be used for linux development as well by
configuring gn appropriately, as it is a superset of the webrtc checkout:
fetch --nohooks webrtc_android
gclient sync
You also must generate GN projects with:
--args='target_os="android" target_cpu="arm"'
More information on getting the code, compiling and running the AppRTCMobile
app can be found at:
https://webrtc.org/native-code/android/
To use the Java API, start by looking at the public interface of
org.webrtc.PeerConnection{,Factory} and the org.webrtc.PeerConnectionTest.
To understand the implementation of the API, see the native code in src/jni/pc/.
