Android 从LibVLC-android到自编译ijkplayer播放H265 RTSP

概述

ijkplayer: Android/iOS video player based on FFmpeg n3.4, with MediaCodec, VideoToolbox support.
官方的描述就这么简单的一句话，但丝毫都不影响它的强大。

从LibVLC 到 ijkplayer

截止到2023.7.20
LibVLC-Android 最大的问题在与OOM，测试了多个版本后最终选择放弃:
3.1.0/3.2.5/3.3.5/3.5.0/3.6.0/4.0.0-eap1到4.0.0-eap11, 内存随着播放次数增加而递增，到最终出现OOM
4.0.0-eap12: OOM 解决了，setVolume不工作了…

PS
4.0.0-eap12: OOM还和绑定的播放窗口有关, 传入SurfaceView/TextureView是内存泄露问题依然存在；
直到使用了org.videolan.libvlc.util.VLCVideoLayout才得以解决。
另外一个问题是，org.videolan.libvlc.util.VLCVideoLayout在画面切换、覆盖时会出现残留、画面比例失调等问题。

下载了源码编译
vlc-android

export ANDROID_NDK=/home/anson/Android/Sdk/ndk/android-ndk-r14b
export ANDROID_SDK=/home/anson/Android/Sdk
buildsystem/compile.sh -l -a arm

生成AAR只需要加上 -r 参数即可

OOM问题依旧~ 跟4.0.0-eap12还是有区别

当然也考虑过其他的播放插件如
ExoPlayer, 没有H265，android exoplayer rtsp example
在这里插入图片描述
迁移到了 AndroidX Media3 1.1.0 release.

This is the last planned release of the com.google.android.exoplayer2 artifacts. 
This project is now deprecated. All users should migrate to androidx.media3 (which contains the same ExoPlayer code). 
See the migration guide for more details, including a script to help with the migration

之前没试过，然后下载下来试了下，DEMO APK都跑不了，呵呵，非免费

GSYVideoPlayer
Android–GSYVideoPlayer框架实现播放视频
怎么说好呢，这是个大合集，EXO, IJK…一样解决不了 RTSP + H265

rtsp-client-android
一些兼容性问题，不出图。

使用ijkplayer

ijkplayer接入方式说明

从gradle导入的ijkplayer 是不能播放RTSP的

implementation "tv.danmaku.ijk.media:ijkplayer-java:0.8.8"
implementation "tv.danmaku.ijk.media:ijkplayer-armv7a:0.8.8"

ijkplayer已经停更好几年了，NDK还是用了 NDK10-NDK14

export ANDROID_NDK=/home/anson/Android/Sdk/ndk/android-ndk-r14b
export ANDROID_SDK=/home/anson/Android/Sdk

ARCH=armv7a

echo ">> INIT "
git checkout -B latest k0.8.8

SO 库

android/ijkplayer/ijkplayer-armv7a/src/main/libs/armeabi-v7a/
├── libijkffmpeg.so
├── libijkplayer.so
└── libijksdl.so

这里偷个懒，使用so库即可，build.gradle:

implementation "tv.danmaku.ijk.media:ijkplayer-java:0.8.8"
//这个不要，直接使用编译出来的so库
//implementation "tv.danmaku.ijk.media:ijkplayer-armv7a:0.8.8"

一些问题

编译完成后，可以尝试在AndroidStudio中打开ijkplayer的示例项目。AndroidStudio和gradle已经物是人非，使用一些需要修改成一些兼容的版本等配置信息。

播放 H265 RTSP

如果播放不了，尝试检查下播放器的配置：

 ijkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "mediacodec-all-videos", 1);
 ijkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "mediacodec-hevc", 1);
 ijkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_FORMAT, "rtsp_transport", "tcp");

总的来说，ijkplayer 的使用与系统的MediaPlayer很相近。一些优化和延迟可以参考文末的链接。

PS: 若需要频繁切换播放源，特别是一些在线视频，不要吝啬多创建几个ijkplayer的实例，实例的复用不见得可以省多少资源，反而会带来许多意料之外的问题。
