JeffVideoCache Architecture

The core of JeffVideoCache is placed on the client, and the local server and client do a good job of data synchronization

1.How to use

1.1 Initialization

Set JeffVideoCache when the program starts ----> SDK initialization configuration

File saveFile = StorageUtils.getVideoFileDir(this);
if (!saveFile.exists()) {
    saveFile.mkdir();
}
VideoProxyCacheManager.Builder builder = new VideoProxyCacheManager.Builder().
        setFilePath(saveFile.getAbsolutePath()).    //File location
        setConnTimeOut(60 * 1000).                  //Connection timeout
        setReadTimeOut(60 * 1000).                  //Read timeout
        setExpireTime(2 * 24 * 60 * 60 * 1000).     //Expire timeout
        setMaxCacheSize(2 * 1024 * 1024 * 1024);    //Cache Size limit
VideoProxyCacheManager.getInstance().initProxyConfig(builder.build());

Initialization configuration:

• 1.Set Cache File location
• 2.Set the Connection timeout
• 3.Set the Read timeout
• 4.Set the cache Expire timeout
• 5.Set the cache size limit

1.2 Build local proxy url

playUrl = ProxyCacheUtils.getProxyUrl(uri.toString(), null, null);

public static String getProxyUrl(String videoUrl, Map<String, String> headers, Map<String, Object> cacheParams)

You can pass in headers, or pass in other additional parameters, according to your own needs

The constructed url is mainly base64 encoded

1.3 Initiate a request

VideoProxyCacheManager.getInstance().startRequestVideoInfo(videoUrl, headers, extraParams);

public void startRequestVideoInfo(String videoUrl, Map<String, String> headers, Map<String, Object> extraParams)

1.4 Set up cache listener

VideoProxyCacheManager.getInstance().addCacheListener(videoUrl, mListener);

mListener:

public interface IVideoCacheListener {

    void onCacheStart(VideoCacheInfo cacheInfo);

    void onCacheProgress(VideoCacheInfo cacheInfo);

    void onCacheError(VideoCacheInfo cacheInfo, int errorCode);

    void onCacheForbidden(VideoCacheInfo cacheInfo);

    void onCacheFinished(VideoCacheInfo cacheInfo);
}

1.5 Set now playing link

VideoProxyCacheManager.getInstance().setPlayingUrlMd5(ProxyCacheUtils.computeMD5(videoUrl));

1.6 Pause cache task

VideoProxyCacheManager.getInstance().pauseCacheTask(mVideoUrl);

1.7 Resume cache task

VideoProxyCacheManager.getInstance().resumeCacheTask(mVideoUrl);

1.8 Drag the video progress bar

long totalDuration = mPlayer.getDuration();
if (totalDuration > 0) {
    float percent = position * 1.0f / totalDuration;
    VideoProxyCacheManager.getInstance().seekToCacheTaskFromClient(mVideoUrl, percent);
}

1.9 stop cache task and release resources

VideoProxyCacheManager.getInstance().stopCacheTask(mVideoUrl);
VideoProxyCacheManager.getInstance().releaseProxyReleases(mVideoUrl);
