万能播放器
一个编译后大小不足10兆的万能解码播放器
更多惊喜：https://bbs.pediy.com/user-854079-1.htm
思考：（可在帖子下方留言）
吃苹果需要要知道树是怎么栽不
海洋关心河流是从哪里汇入的不
ffmpeg5.0目前只能播放本地视频，改进完成后，将发布
支持https播放
ffmpeg-4.4.1 + OPEN-SSL1.0.2t
一个jar + SO 播放类型市面上99%类型的视频
全世界最强大的解码器，没有之一，目前各种系统平台下的播放均是在ffmpg基本上开发的

如果你用的是我之前的开源，没有影响API没有改变 |
|
|
|
|
|
mediaPlayer.setOnCheckDecodeListener 打开被注释的这个回调，可查看所有支持类型 |
|
|
有这么回答的?看来你也是拿来主义。 因为你自己都不确定，要别人去看。如果直接回答是或否，答错了就更..... |
|
|
大家都是拿来主义吧，我不至于自己搞解码算法吧，谁也不会自己搞个手机系统吧，不想用的话，这个问题我也不想回答，不想当拿来主义，可以自己去下载源码，或自己写解码 |
|
|
不全是拿来主义。如果推荐的东西自己都不完全了解，那就不应该推荐？ |
|
|
不好意思，不清楚你什么目地，我搞这个，是为了方便大家可以更轻松的开发属于自己的视频播放，不知为何你要纠结这个问题上，有能力的人可以自己去编译解码工具，能力不够或想省些时间的话，可以集成我编译的。如果你也在用，可把遇到的问题放帖子下面，要是你有更好的解决方案，也可以拿出来分享一下
