The Androidvideocache is a video/audio cache library that uses local proxies to enable edge-to-bottom playback, which is very simple to use.Httpproxycacheserver is the main class, is a proxy server, you can configure the number of cache files, the size of the cache file, the directory of cache files and the cache file naming algorithm, the file cache is based on the LRU algorithm, using Builder to configure: // Builder cachedirectory (file file);

In the android native Media Player, mediaplayerservice controls the Media Player. mediaplayerservice creates a mediaplayer and mediaplayer. the native method of Java calls the method in android_media_mediaplayer.cpp through JNI, and then calls mediaplayer. the method in CPP. mediaplayer calls the method in mediaplayerservice through the IPC Mechanism. mediaplayerservice selects a different player to play the music by judging the file format. When it i

higher quality network video at limited bandwidth. For most professionals, the h.265 coding standard is not unfamiliar, it is itu-tvceg after the development of the video coding standards. The h.265 standard mainly revolves around the existing video coding standard, which, in addition to preserving some of the original technologies, increases the correlation between the code stream, the encoding quality, the delay, and the complexity of the algorithm. The main contents of h.265 research include

This article mainly introduces WEBRTC in each platform debug or log viewing mode, to facilitate troubleshooting, including Bs,pc,android,ios (this series of articles reproduced please indicate the source, blog Park rtc.blacker).1, Browser development:This development method does not need to download and compile WEBRTC source code (many people are "dead" here, but it is really troublesome, the reason is not to repeat), directly invoke the browser provi

I recently watched the playback latency problem in Android. After reading the code, I found that the latency function in the audiotrack class has the following comments: /* Returns this track's latency in milliseconds. * This includes the latency due to AudioTrack buffer size, AudioMixer (if any) * and audio hardware driver. */ Powerful enough. I used to calculate the latency Based on the b

Recently I wrote a simple android Audio/Video Player: 1. Scan and play sdcard music files 2. The lyrics synchronization function (only the line can be synchronized, because it is in lrc format. If you need to synchronize to every word, you need to parse the krc file like kogou) 3. Video Playback 4. Play the network video function (listview can pull down and refresh to obtain network disconnection data)
