[android-developers] Re: video streaming from Android without saving on sdcard

Thank you for response.

Because i dont quite know ho to do it using HTTP server :)

For example how Apache can write input stream into mp4 file.

Could you please give me an example?

Why not put the mp4 on an HTTP server?  Why would you write your own server for this?

                    System.out.println("endmain");
            }
    }

I test it on Android 2.2.2 (HTC quiet brilliant) and all works fine. When I press "start" button Server create file and record data from stream to file. After this file is normally play in VLC player and etc.

But when I test it on Android 4.0.4 (Galaxy S2) Server create file and record data from stream to file but not play in VLC (and other players too) and give me error 

mp4 error: MP4 plugin discarded (no moov,foov,moof box)
avcodec error: Could not open �codec demux error: Specified event object handle is invalid
ps error: cannot peek
main error: no suitable demux module for `file/:///C:/1345461283455.mp4'

I also try to upload this file to youtube, but after upload youtube give me error like file format is unsupported.

But Android 4.0.4 (Galaxy S2) succesfully create and then play file when I save it on phone memory (not stream to server)

I think problem maybe on server side, or something changed on android 4.0.4.

Please, help me.

Thanks in advance.
