Recently compiling ijkPlayer, I encountered some problems, here are some notes, the specific use needs baidu query.Copy the code

Environment to prepare

| my environment is VMware + ubuntu (20.04.2.0), install the virtual machine, install ubuntu.

  1. Modify the Linux software source

    Open the command line, enter the following commands, and follow the prompts. 1. Backup source file sudo cp/etc/apt/sources list/etc/apt/sources list. The back 2. Sudo gedit /etc/apt/sources.list In the editor that pops up, clear all the contents. Copy the following and paste it in. Source (ali) deb http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse 3. Save, then close the editor. Sudo apt-get update 5. You are advised to run sudo apt-get updateCopy the code

  2. Install the required software

    • Install gitsudo apt-get install git
    • Install yasmsudo apt-get install yasm
    • Install pythonsudo apt-get install python

      Python was installed to address compile-time reportingERROR: Failed to create toolchain
    • Install file, libnCURES, and execute the following commands in turn 
      sudo apt install apt-file
sudo apt-file update
sudo apt-file find libncurses.so.5
sudo apt install libncurses5
Copy the code

      Solve the problem when compiling FFMPEGBFD: libncurses.so.5: cannot open shared object file: No such file or directoryThe problem of

  3. The development environment

  • You can download the Jdk directly from Oracle’s official website.

2. Modify the environment variable sudo gedit /etc/profile 3. At the end of the open file, #set oracle JDK environment export JAVA_HOME=/usr/lib/ JVM/jdK-14.0.1 # JRE_HOME=${JAVA_HOME}/jre export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib export PATH=${JAVA_HOME}/bin:$PATH 4. Source /etc/profile 5. JDK sudo update-alternatives --install /usr/bin/java /usr/lib/jvm/jdk-14.0.1/bin/ Java 300 Test whether Java -version ' 'was successfully installedCopy the code

  • Android Sdk download address

    2. Update the SDK, run the following command (upgrade all) 'sudo tools/android update SDK --no-ui', if the prompt y/n, always enter y, press Enter. 3. Set the environment variable sudo gedit /etc/profile. At the end of the open file, Add the following content # android SDK (the path will be subject to their own) export ANDROID_SDK = / home/bingjiazheng ANDROID_SDK/android SDK - Linux export PATH=${PATH}:$ANDROID_SDK/tools:$ANDROID_SDK/platform-tools 5. Enable environment variables to take effect source /etc/profile 6. Adb version is tested successfully (if not, restart it again)Copy the code

  • Android NDK download address (r10E or R14B)

    Sudo./android-ndk-r10e-linux-x86_64.bin If you do not have permission to operate the directory (a lock has been added), Enter 'sudo chown -r STG android-ndk-r10e' 2. Set the environment variable sudo gedit /etc/profile 3. #android NDK export ANDROID_NDK= Installation PATH /android-ndk-r10e/ export PATH=$PATH:$ANDROID_NDK 4. Enable environment variables to take effect source /etc/profile 5. Check whether the test is successful. (If the test does not take effect, restart the test again.Copy the code
  1. The network environment
    • It is recommended to configure proxy in network environment to improve the speed of Clone ijkPlayer-Android and FFMPEG download.
    • It is recommended to set git network proxy, ffmPEG, Openssl and other libraries sometimes clone error
    Git config --global http.proxy http://127.0.0.1:1089 git config --global HTTPS http://127.0.0.1:1089 // Set the socks5 proxy git config --global http.proxy socks5://127.0.0.1:1080 git config --global Proxy git config --global --unset http.proxy git config --global --unset . The HTTPS proxy / / view the git set up git config - global - l check the environment variable env | grep -i proxyCopy the code
