Live Streaming Topic
<p>This could be quite an intresting topic for people who are intrested in livestreaming <strong>from</strong> your <em>device</em> <strong>to</strong> a <em>webserver</em>. (Primary Android/Java)
I have finally found a way on how to livestream from my device's camera to my webserver (website). On a wifi network it takes approx. 1 frame/ second to show on a wifi network, It also works on EDGE/3G network. In this topic/question, I want to discuss new techniques, improvements, ideas about livestreaming as I will share mine with yours (codes are appreciated too.)</p>

<p>My code repeatedly takes a snapshot from the camera preview using setOneShotPreviewCallback() to call onPreviewFrame(). The frame is delivered in YUV format so raw2jpg() converts it into 32 bit ARGB for the jpeg encoder. NV21 is a YUV planar format.</p>

<p>getPicture() is called, by the application, and produces the jpeg data for the image in the private byte array mCurrentFrame and returns that array. </p>

<p>After this, the byteArray mCurrentFrame gets Base64Encoded and send to my webserver in a HTTP POST method together with the string value of Base64 and a own ID code so people won't be able to also send another image to it. At the webserver, it gets decoded again and putted into the file test.jpg. PHP and Javascript is running on the webserver. PHP gets the POST method and JavaScript reloads the image every 750 seconds. This is basically how it works.</p>

<p>Now I am very intrested in your ideas, improvements and other things you would like to add/ask. <strong>Here are some of my questions:</strong></p>

<p>1) What would be the best method for live streaming WITH audio? Video Recording OR my method + Audio recording?</p>

<p>2) How would you approach video record streaming?</p>

<p>3) How would you stream audio to the webserver? (<strong>Main goal</strong>) (With Java, PHP and JavaScript)</p>

<p>4) I am also planning to add typical live streaming feautures to i, e.g. when a famous person appears, you could have the ability to show his name while you are live streaming, or just add an image from your sd directory to your livestream. Would you also decode it and overlay the image, or put the image in your livestream in some way?</p>

<p>This topic is primarly for questions, so please this could be some great help for some people out here. Therefore I added a bounty of 50 (woot!) rep to it.</p>

<p>Sincerely,
