Android Ogg/Theora Streamer : Giss Streamer

GISS Ogg/Theora Streamer v 1.3

This is the Ogg/Theora streamer based on the java vorbis library for android : Vorbis library for android and using a native theora library.

It will only work with version of android >= 2.1 and will not work on devices with simplified processors, it was tested with success on an HTC Desire, it would not work on an HTC Tattoo, because it doesn't support floating point operations.

If works on many other recent phones like Samsung A2 or Oppo Find X3 Lite ( tested ).

You should enter your stream parameters in the following screens and type 'Start' to start your stream.

In case of an error, you will see an error in the status message or will have a pop-up alert :

Synopsis

Enter the stream server parameters in the main screen, than go to 'Stream quality' screen and enter the parameters you choose :

• Width and Height : size of the video that is transmitted ( different form the size you see on the screen )
• Framerate : framerate of the video stream
• Video quality : theora encoding quality ( 1 to 16 )
• Audio bitrate : the audio bitrate transmitted to the server ( usually 64/96/128/256 )
• Audio channels : the number of requested channels ( generally 2 : stereo, the mic is mono but output is stereo ).
• Audio rate : the audio rate of the recording ( usually 44100 ).

Finally, enter your stream metadata in the 'Meta Data' screen :

• Name : name of the stream
• Description : description of the stream
• Genre : genre
• More info : an url that describes more your project.

Then, click the 'Start' button and the stream should start.

Notes

On small android models, use a low value for the video size ( 160x128 ) as well as a low framerate ( 3 ).

In fact, here the trick is to launch a streaming and see how many frames you get per second, and then stop the stream and enter this value in the framerate and start again : this guarantees an optimal synchronisation of audio and video.
