直播视频流的Android应用 [英] Live video streaming application on Android
问题描述
我试图建立从Android的流视频直播实时视频流应用程序。
I am trying to build a live video streaming application that streams live video from Android.
使用MediaRecorder类，我能够捕捉到的视频数据3GP的形式，与H263 codeCS。
Using the MediaRecorder class, I am able to capture the video data in the form of 3gp, with h263 codecs.
然而，当我跑我的应用程序，流媒体，我得到一个2-3秒的延迟，在服务器端。
However, when I run my application and stream media, I get a 2-3 second delay at the server side.
为什么会出现这种延迟？是否有任何内部缓冲区，我需要刷新？是否有使用MediaRecorder类除了视频流的其他方式？
Why am I getting this delay? Are there any internal buffers that I need to flush? Are there other ways of streaming video apart from using MediaRecorder class?

If you're set on RTMP streaming from Android, the best solution is MediaCodec + FFmpeg + librtmp. This avoids any hacky "detect the NAL Unit within the bytestream" business but requires Android 4.3. Skate where the puck is going...
我已经开发了一个开源SDK 演示RTMP流用的 FFmpeg的+ librtmp为pre-内置共享库。该SDK是专注于HLS流，但RTMP支持是present。
I've developed an open source SDK that demonstrates RTMP streaming with FFmpeg + librtmp as pre-built shared libraries. The SDK is focused on HLS streaming, but RTMP support is present.
如果你想帮助建设的FFmpeg自己为Android（带或不带librtmp），看看我的指南。
