41 | ``` 42 | 43 | 硬件解码跟软件解码我们通常称为硬解跟软解，是通过移动设备观看视频时会碰到的一个概念。 44 | 首先来说下两者的区别： 45 | 硬件解码：硬件解码从字面意思很容易理解，就是通过硬件进行视频的解码工作，其中硬件解码是由GPU来进行的，使用GPU解码能够降低CPU的工作负荷，降低功耗。 46 | 软件解码：软件解码则是通过软件本身占用的CPU进行解码，所以会增加CPU工作负荷，提升功耗， 47 | 硬解及软解的优点跟缺点： 48 | 硬解优点：播放出来的视频较为流畅，并且能够延长移动设备播放视频的时间； 49 | 硬解缺点：所解码视频格式收到GPU影响，无法部分全部视频，画质也不够清晰。 50 | 软解优点：软解能够解码所有视频格式文件，且画质更加清晰； 51 | 软解缺点：由于软解加大CPU工作负荷，会占用过多的移动CPU资源，如果CPU能力不足，则软件也将受到影响。 52 | -------------------------------------------------------------------------------- /app/.gitignore: -------------------------------------------------------------------------------- 1 | /build 2 | -------------------------------------------------------------------------------- /app/build.gradle: -------------------------------------------------------------------------------- 1 | apply plugin: 'com.android.application' 2 | 3 | android { 4 | compileSdkVersion 26 5 | buildToolsVersion "26.0.0" 6 | defaultConfig { 7 | applicationId "com.vincent.videocompress" 8 | minSdkVersion 19 9 | targetSdkVersion 22 10 | versionCode 1 11 | versionName "1.0" 12 | testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" 13 | } 14 | buildTypes { 15 | release { 16 | minifyEnabled false 17 | proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 18 | } 19 | } 20 | } 21 | 22 | dependencies { 23 | compile fileTree(include: ['*.jar'], dir: 'libs') 24 | androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', { 25 | exclude group: 'com.android.support', module: 'support-annotations' 26 | }) 27 | compile 'com.android.support:appcompat-v7:26.+' 28 | compile 'com.android.support.constraint:constraint-layout:1.0.2' 29 | testCompile 'junit:junit:4.12' 30 | compile project(':videocompressor') 31 | } 32 | -------------------------------------------------------------------------------- /app/proguard-rules.pro: -------------------------------------------------------------------------------- 1 | # Add project specific ProGuard rules here. 2 | # By default, the flags in this file are appended to flags specified 3 | # in D:\Android_SDK/tools/proguard/proguard-android.txt 4 | # You can edit the include path and order by changing the proguardFiles 5 | # directive in build.gradle. 6 | # 7 | # For more details, see 8 | # http://developer.android.com/guide/developing/tools/proguard.html 9 | 10 | # Add any project specific keep options here: 11 | 12 | # If your project uses WebView with JS, uncomment the following 13 | # and specify the fully qualified class name to the JavaScript interface 14 | # class: 15 | #-keepclassmembers class fqcn.of.javascript.interface.for.webview { 16 | # public *;
