vlc for android 编译过程

相逢意气为君饮，系马高楼垂柳边。这篇文章主要讲述vlc for android 编译过程相关的知识，希望能为你提供帮助。
gradle的相关问题
1.下载gradle会相当慢可以修改脚本里面的下载地址推荐这个网站https://services.gradle.org/distributions/
2.gradle的缓存下载相当慢可以修改build.gradle 把里面的修改成图片这样阿里云的

文章图片

maven { url "http://maven.aliyun.com/nexus/conten/groups/public/" }

jcenter { url \'http://maven.aliyun.com/nexus/content/repositories/jcenter\' }

3.删除Ubuntu自带的java

apt-cache search java | awk \'{print($1)}\' | grep -E -e \'^(ia32-)?(sun|oracle)-java\' -e \'^openjdk-\' -e \'^icedtea\' -e \'^(default|gcj)-j(re|dk)\' -e \'^gcj-(.*)-j(re|dk)\' -e \'java-common\' | xargs sudo apt-get -y remove apt-get -y autoremove dpkg -l | grep ^rc | awk \'{print($2)}\' | xargs sudo apt-get -y purge bash -c \'ls -d /home/*/.java\' | xargs sudo rm -rf rm -rf /usr/lib/jvm/*

4.遇到下面的问题

make[2]: Leaving directory \'/vlc/vlc-android/vlc/build-android-aarch64-linux-android/po\' Making install in share make[2]: Entering directory \'/vlc/vlc-android/vlc/build-android-aarch64-linux-android/share\' GENvlc.appdata.xml make[3]: Entering directory \'/vlc/vlc-android/vlc/build-android-aarch64-linux-android/share\' make[3]: Nothing to be done for \'install-exec-am\'. GENvlc.appdata.xml /usr/bin/mkdir -p \'/vlc/vlc-android/vlc/build-android-aarch64-linux-android/install/share/metainfo\' /usr/bin/install -c -m 644 ../../share/vlc.appdata.xml \'/vlc/vlc-android/vlc/build-android-aarch64-linux-android/install/share/metainfo\' /usr/bin/install: cannot stat \'../../share/vlc.appdata.xml\': No such file or directory make[3]: *** [Makefile:1355: install-appdataDATA] Error 1 make[3]: Leaving directory \'/vlc/vlc-android/vlc/build-android-aarch64-linux-android/share\' make[2]: *** [Makefile:1691: install-am] Error 2 make[2]: Leaving directory \'/vlc/vlc-android/vlc/build-android-aarch64-linux-android/share\' make[1]: *** [Makefile:1555: install-recursive] Error 1 make[1]: Leaving directory \'/vlc/vlc-android/vlc/build-android-aarch64-linux-android\' make: *** [Makefile:2024: install] Error 2

只需要把

cp ./vlc-android/vlc/share/vlc.appdata.xml.in.in ./vlc-android/vlc/share/vlc.appdata.xml

自己注意路径哈
5.配置gradle离线
编译成功后第二次编译有时候会下载更新些东西很麻烦导致编译很慢可以配置离线
编辑compile.sh把里面要使用gradlew命令的都手动加一个参数--offline
6.配置ffmpeg的代码
自带的脚本用git下载ffmpeg会很慢如果有外网环境可以自己下载然后放到相应的目录

git clone http://git.videolan.org/git/ffmpeg.git tar -czf ffmpeg.tar.xz ffmpeg/

然后重命名需要的git对应的hash版本例如我现在用的eaff5fcb7cde8d1614755269773d471d3a3d1bfc这个值可以在vlc/contrib/src/ffmpeg/rules.mak中的FFMPEG_HASH
找到

mv ffmpeg.tar.xz ffmpeg-eaff5fcb7cde8d1614755269773d471d3a3d1bfc.tar.xz echo "eaff5fcb7cde8d1614755269773d471d3a3d1bfc ../../contrib/tarballs/ffmpeg-eaff5fcb7cde8d1614755269773d471d3a3d1bfc.tar.xz"> > ffmpeg-eaff5fcb7cde8d1614755269773d471d3a3d1bfc.githash

7.出现如下问题

libncurses.so.5: cannot open shared object file

会导致编译contrib下面的代码出现问题执行如下安装即可

apt-get install libncurses5

8.血的教训记得编译release版本不然太多的错误了

compile.sh --release

9.解决如下问题

lib/fseterr.c: In function \'fseterr\': lib/fseterr.c:77:3: error: #error "Please port gnulib fseterr.c to your platform! Look at the definitions of ferror and clearerr on your system, then report this to bug-gnulib." 77 |#error "Please port gnulib fseterr.c to your platform! Look at the definitions of ferror and clearerr on your system, then report this to bug-gnulib." |^~~~~ make[3]: *** [lib/fseterr.o] Error 1 make[3]: *** Waiting for unfinished jobs....

直接把vlc/extras/tools/bison/lib/fseterr.c中的fseterr (FILE *fp)的内容删除即可改成空函数
10.解决SDK的license问题我是用命令行安装的
