vlc 2.5.5 compile
deschttps://github.com/videolan/vlc-android/releases
에서 버전 다운받아서 해도됨 버전별로 받아서 압축풀때 폴더이름은 vlc-android[버전] 이렇게 되는데 vlc-android 으로 변경 해주고 컴파일 해야함
https://developer.android.com/ndk/downloads/older_releases#ndk-15c-downloads
ndk 버전별로 받아두고 해야함 버전마다 빌드가 되는 버전이 따로 있음

SDK & Android Studio
- Go to Android SDK/IDE page.
- Android Studio is recommended, but not mandatory!
- Download the command-line tools
mkdir android-sdk cd android-sdk; unzip tools_r25.2.3-linux.zip ./tools/bin/sdkmanager --update
Android NDK
- Check that the SDK installation is correct.
- Go to the Android NDK page and download the NDK r14b for Linux.
- Decompress it to install
export ANDROID_SDK=/path/to/android-sdk
export ANDROID_NDK=/path/to/android-ndk

밑의 protobuf 에러 날때 protoc 설치
make: *** [.protobuf] Error 2
contribs: make failed
1. apt로 설치...
sudo apt-get install libprotobuf-dev protobuf-compiler2. 직접 다운 설치
protoc-3.2.0 install
# Make sure you grab the latest version
curl -OL https://github.com/google/protobuf/releases/download/v3.2.0/protoc-3.2.0-linux-x86_64.zip
# Unzip
unzip protoc-3.2.0-linux-x86_64.zip -d protoc3
# Move protoc to /usr/local/bin/
sudo mv protoc3/bin/* /usr/local/bin/
# Move protoc3/include to /usr/local/include/

바이트 버퍼 그대로 전달을 받자
vlc-android/libvlc/jni/libvlcjni-media.c 에 함수 추가

android org.videolan.libvlc.Media.java 에

===== FTP 언어셋 UTF-8로 강제 시키기 ===
vlc/modules/access/ftp.c 를 수정해야함 그러나 빌드시에 해당 파일이 새로운파일로 대체 되기 때문에
그에 맞추어 파일을 빌드 완료 되기전에 빠르게 수정해야함 [새로운 파일로 대체 안되는 방법이 있을것 같지만 찾지 못함..ㅠ]
static int Connect( vlc_object_t *p_access, access_sys_t *p_sys, const char *path ){
.......
///////// 추가 //////////
if( ftp_SendCommand( p_access, p_sys, "OPTS UTF8 ON" ) < 0 || ftp_RecvCommand( p_access, p_sys, NULL, NULL ) != 2 ) { msg_Err( p_access, "cannot set ftp UTF8 mode" ); goto error; }
///////// 추가끝 //////////
return 0;
