Streaming video from Android camera to server
提问by JCL
I've seen plenty of info about how to stream video from the server to an android device, but not much about the other way, ala Qik. Could someone point me in the right direction here, or give me some advice on how to approach this?
我已经看到了很多关于如何将视频从服务器流式传输到 android 设备的信息，但关于其他方式的信息并不多，ala Qik。有人可以在这里指出我正确的方向，或者就如何解决这个问题给我一些建议？

I have hosted an open-source project to enable Android phone to IP camera:
我主持了一个开源项目，以启用 Android 手机到 IP 摄像头：
http://code.google.com/p/ipcamera-for-android
http://code.google.com/p/ipcamera-for-android
Raw video data is fetched from LocalSocket, and the MDAT MOOV of MP4 was checked first before streaming. The live video is packed in FLV format, and can be played via Flash video player with a build in web server :)
原始视频数据是从 LocalSocket 获取的，并且在流式传输之前首先检查 MP4 的 MDAT MOOV。实时视频以 FLV 格式打包，可以通过内置网络服务器的 Flash 视频播放器播放:)

Took me some time, but I finally manage do make an app that does just that. Check out the google code page if you're interested: http://code.google.com/p/spydroid-ipcamera/I added loads of comments in my code (mainly, look at CameraStreamer.java), so it should be pretty self-explanatory. The hard part was actually to understand the RFC 3984 and implement a proper algorithm for the packetization process. (This algorithm actually turns the mpeg4/h.264 stream produced by the MediaRecorder into a nice rtp stream, according to the rfc)
我花了一些时间，但我终于设法制作了一个可以做到这一点的应用程序。如果您有兴趣，请查看谷歌代码页：http: //code.google.com/p/spydroid-ipcamera/我在我的代码中添加了大量注释（主要是查看 CameraStreamer.java），所以它应该是不言自明。困难的部分实际上是理解 RFC 3984 并为打包过程实施适当的算法。（根据 rfc，该算法实际上将 MediaRecorder 生成的 mpeg4/h.264 流转换为不错的 rtp 流）
Bye
再见

I'm looking into this as well, and while I don't have a good solution for you I did manage to dig up SIPDroid's video code:
我也在研究这个，虽然我没有一个好的解决方案，但我确实设法挖掘了 SIPDroid 的视频代码：

I've built an open-source SDK called Kickflipto make streaming video from Android a painless experience.
我已经构建了一个名为Kickflip的开源 SDK，以使来自 Android 的流视频成为一种轻松的体验。
The SDK demonstrates use of Android 4.3's MediaCodecAPI to direct the device hardware encoder's packets directly to FFmpeg for RTMP(with librtmp) or HLSstreaming of H.264 / AAC. It also demonstrates realtime OpenGL Effects (titling, chroma key, fades) and background recording.
SDK 演示了使用 Android 4.3 的MediaCodecAPI 将设备硬件编码器的数据包直接定向到 FFmpeg，用于RTMP（使用 librtmp）或H.264/AAC 的HLS流。它还演示了实时 OpenGL 效果（标题、色度键、淡入淡出）和背景记录。
Thanks SO, and especially, fadden.

I am able to send the live camera video from mobile to my server.using this link see the link
Refer the above link.there is a sample application in that link. Just you need to set your service url in RecordActivity.class.
我可以将实时摄像头视频从手机发送到我的服务器。使用此链接 查看链接
请参阅上面的链接。该链接中有一个示例应用程序。只是你需要在 RecordActivity.class 中设置你的服务 URL。
Example as: ffmpeg_link="rtmp://yourserveripaddress:1935/live/venkat";
例如： ffmpeg_link="rtmp://yourserveripaddress:1935/live/venkat";
we can able to send H263 and H264 type videos using that link.
我们可以使用该链接发送 H263 和 H264 类型的视频。

Mux (my company) has an open source android appthat streams RTMP to a server, including setting up the camera and user interactions. It's built to stream to Mux's live streaming API but can easily stream to any RTMP entrypoint.
Mux（我的公司）有一个开源 Android 应用程序，可以将 RTMP 流式传输到服务器，包括设置相机和用户交互。它旨在流式传输到 Mux 的实时流式传输 API，但可以轻松流式传输到任何 RTMP 入口点。
