display video from h264 stream of an ip camera in android

In my ndroid application, I need to display H264 streams from a GrandStream IP Camera. I saw some topics about decoding H264 frames with MediaCodec in Android, but I really don't know where to start.
Before searching this topic, I thought that there were planty of open source library for that purpose but It seems there is not!
Can you show me a way where to start? Should I use Android's MediaCodec or is there any open source Java library for that?

You can refer to this site, It has a very thoroughly discussion and sample about Android Media Codec

Recording and watching video live streaming using red 5 and rtsp for android

I have spent enough time searching for a solution but I am not sure which way I should go. That is why I am asking question here.
I want to make an application from where I can record a video and same video will be shown live on any other device connected to the network or it can be on web using JWplayer or some thing like that.
Now I have done enough R&D and we are not considering WOwza server (as it is paid) . So on web side we have already implemented in which web cam in recording video and which can be seen on our web site and also on android and iphone browsers live.
But problem with red 5 is that is does not give support to RTSP (it only supports RTMP) unlike Wowza which handles RTSP internally and convert it into RTMP.
I have found few links who suggested client side RTMP handling what so far no success.
Convert video Input Stream to RTMP
This links explains lot of things but I am not sure which way I should spend my time or it is possible to convert RTSP into RTMP for red 5 server.

this guy has achieve this functionality I guess but we are looking for the native application.
Please suggest me in the right direction I should go and invest my time live record and watch video stream.
We can use other servers which are open source rather than red 5 , if it fulfill my needs on both iOS, android and web else I ll have to go with wowza which I dnt want for now.

Get frame from live video stream

I am streaming live video from my camera on my android phone to my computer using the MediaRecorder class.
recorder.setCamera(mCamera);
recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setOutputFile(uav_UDP_Client.pfd.getFileDescriptor());
recorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);
That's the basic idea. So I would like to show this stream in real time. My plan is to use FFMpeg to turn the latest frame into a .bmp and show the .bmp on my C# program every time there is a new frame.
The problem is there is no header until I stop the recording. So I can not use FFMpeg unless there is a header. I've looked at spydroid and using RTP but I do not want to use this method for various reasons.
Any ideas on how I can do this easily?

You can consider streaming a MPEG2 TS and playing it back on your screen or you can also stream H.264 data over RTP and use a client to decode and display the same.
In Android, there is a sample executable which performs RTP packetization of H.264 stream and streams it over the network. You can find more details about the MyTransmitter from this file, which could serve as a good reference to your solution.
Additional Information
In Android 4.2.0 release onwards, there is a similar feature supported by the framework called Miracast or Wi-Fi Display which is standardized by Wi-Fi forum, which is a slightly complex use-case.

Convert video Input Stream to RTMP

I want to stream video recording from my android phone to network media server.
The first problem is that when setting MediaRecorder output to socket, the stream is missing some mdat size headers. This can be fixed by preprocessing that stream locally and adding missing data to stream in order to produce valid output stream.
The question is how to proceed from there.
How can I go about output that stream as an RTMP stream?

First, let's unwind your question. As you've surmised, RTMP isn't currently supported by Android. You can use a few side libraries to add support, but these may not be full implementations or have other undesirable side effects and bugs that cause them to fail to meet your needs.
The common alternative in this case is to use RTSP. It provides a comparable session format that has its own RFC, and its packet structure when combined with RTP is very similar (sans some details) to your desired protocol. You could perform the necessary fixups here to transmute RTP/RTSP into RTMP, but as mentioned, such effort is currently outside the development scope of your application.
So, let's assume you would like to use RTMP (invalidating this thread) and that the above-linked library does not meet your needs.
You could, for example, follow this tutorial for recording and playback using Livu, Wowza, and Adobe Flash Player, talking with the Livu developer(s) about licensing their client. Or, you could use this client library and its full Android recorder example to build your client.
To summarize:
RTSP
This thread, using Darwin Media Server, Windows Media Services, or VLC
RTMP
This library,
This thread and this tutorial, using Livu, Wowza, and Adobe Flash Player
This client library and this example recorder
Best of luck with your application. I admit that I have a less than comprehensive understanding of all of these libraries, but these appear to be the standard solutions in this space at the time of this writing.
Edit:
According to the OP, walking the RTMP library set:
This library: He couldn't make the library demos work. More importantly, RTMP functionality is incomplete.
This thread and this tutorial, using Livu, Wowza, and Adobe Flash Player: This has a long tutorial on how to consume video, but its tutorial on publication is potentially terse and insufficient.
This client library and this example recorder: The given example only covers audio publication. More work is needed to make this complete.
In short: more work is needed. Other answers, and improvements upon these examples, are what's needed here.

If you are using a web-browser on Android device, you can use WebRTC for video capturing and server-side recording, i.e with Web Call Server 4
Thus the full path would be:
Android Chrome [WebRTC] > WCS4 > recording
So you don't need RTMP protocol here.
If you are using a standalone RTMP app, you can use any RTMP server for video recording. As i know Wowza supports H.264+Speex recording.

Live video feeds in my own android application

I would like to develope a application for viewing a IP camera , DVR video feeds from my own application. Can anyone please tell me the best possible way to achieve it so that the delay is as minimum as possible. What all servers are required to stream the video the formats etc..

androidfan , I believe you need to setup a media server to send & receive video streams.
Red5 will be a good option in your case.
Red5 is an Open Source Flash Server written in Java that supports: Streaming Video , Audio & RTMP protocols.
