Native codecs (libvpx, Opus, Speex)

The app loads libandroidcast_codecs.so for availability probes and future software encode/decode paths.

Current status

Component	Java	Native	Notes
FEC 3/4 + RS	Yes	—	v2 per-shard on wire (`FecShardWire`); v1 monolithic decode still accepted
NACK + retransmit cache	Yes	—	UDP `MSG_NACK`, combined with FEC when enabled
libvpx VP8/VP9	Native	Encode + decode	Screen cast via ImageReader; receiver libvpx (decoder uses `VPX_CODEC_USE_ERROR_CONCEALMENT` when supported) or MediaCodec fallback
Opus / Speex	Probe + static link when `lib*.a` built	Encode/decode JNI sinks	`scripts/build-native-codecs.sh` → CMake autolink

Enable native codecs (developer)

Initialize all third-party submodules:

bash scripts/init-third-party-submodules.sh

Build static libs per ABI (NDK auto-detected via scripts/android-ndk.sh):
```
./scripts/build-native-codecs.sh arm64-v8a
./scripts/build-native-codecs.sh armeabi-v7a   # if shipped in APK
```
If the repo path has spaces, the script stages under /tmp/androidcast-libvpx-$USER.
Gradle / CMake link build/native/<abi>/lib*.a when present and set ANDROIDCAST_HAVE_LIBVPX, ANDROIDCAST_HAVE_OPUS, ANDROIDCAST_HAVE_SPEEX accordingly.
./gradlew assembleDebug

Optional override: ANDROIDCAST_LIBVPX_LIB only applies when its path contains the current ABI name (e.g. .../arm64-v8a/libvpx.a).

ABIs without matching .a files still build; missing codecs are disabled on those architectures.

Stream protection defaults

Default: None (no FEC/NACK)
Enable in Global settings → Stream protection (UDP)
After handshake, sender and receiver negotiate the effective mode (no protocol version bump)
Until negotiation completes, UDP protection stays off; peers without FEC support ignore protected frames
