Streaming audio and video from Android to PC/web?

Doing so is not simple but possible The MediaRecorder API assumes that the output is a random access file, meaning, it can got forth and back for writing the mp4 (or other) file container. As you can see in the ipcamera-for-android, the output file is directed to a socket which is not random access. The fact makes it hard to parse the outgoing stream since the MediaRecorder API will "write" some data like fps, sps/pps (on h264) and so on only when the recording is done.

The API will try to seek back to the beginning of the stream (where the file header exists) but it will fail since the stream is sent to a socket and not to a file Taking the ipcamera-for-android is a good reference, if I recall correctly, before streaming, it records a video to a file, opens the header and takes what it needs from there, than, it start recording to the socket and uses the data it took from the header in order to parse the stream You will also need some basic understanding in parsing mp4 (or other file container you'd want to use) in order to capture the frames. You can do that either on the device or on the server side Here is a good start for writing the stream to a socket: Tutorial I hope it was helpful, there is no good tutorial for parsing and decoding the outgoing streams since it is not so simple...but again, it is possible with some effort Take a look also here to see how to direct the output stream to a stream that can be sent to the server: MediaRecorder Question.

Very helpful bump in the right direction. I will look into those links now. Thanks – ajs Aug 4 at 13:24.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
