+// Unlike other filters, this one uses a grid of GL_POINTs to sample the incoming image in a grid. A custom vertex shader reads the color in the texture at its position 
+// and outputs a bin position in the final histogram as the vertex position. That point is then written into the image of the histogram using translucent pixels.
+// The degree of translucency is controlled by the scalingFactor, which lets you adjust the dynamic range of the histogram. The histogram can only be generated for one
+// color channel or luminance value at a time.
+//
+// This is based on this implementation: http://www.shaderwrangler.com/publications/histogram/histogram_cameraready.pdf
+//
+// Or at least that's how it would work if iOS could read from textures in a vertex shader, which it can't. Therefore, I read the texture data down from the
+// incoming frame and process the texture colors as vertices.

+
+// How To Use:
+// 1) Use your favourite photo editing application to apply a filter to lookup.png from GPUImage/framework/Resources.
+// For this to work properly each pixel color must not depend on other pixels (e.g. blur will not work).
+// If you need more complex filter you can create as many lookup tables as required.
+// E.g. color_balance_lookup_1.png -> GPUImageGaussianBlurFilter -> color_balance_lookup_2.png
+// 2) Use you new lookup.png file as a second input for GPUImageLookupFilter.
+
+// See GPUImageAmatorkaFilter, GPUImageMissEtikateFilter, and GPUImageSoftEleganceFilter for example.
+
+// Additional Info:
+// Lookup texture is organised as 8x8 quads of 64x64 pixels representing all possible RGB colors:
+//for (int by = 0; by < 8; by++) {
+//    for (int bx = 0; bx < 8; bx++) {
+//        for (int g = 0; g < 64; g++) {
+//            for (int r = 0; r < 64; r++) {
+//                image.setPixel(r + bx * 64, g + by * 64, qRgb((int)(r * 255.0 / 63.0 + 0.5),
+//                                                              (int)(g * 255.0 / 63.0 + 0.5),
+//                                                              (int)((bx + by * 8.0) * 255.0 / 63.0 + 0.5)));
+//            }
+//        }
+//    }
+//}
+

+ This equation is a simplification of the general blending equation. It assumes the destination color is opaque, and therefore drops the destination color's alpha term.
+ 
+ D = C1 * C1a + C2 * C2a * (1 - C1a)
+ where D is the resultant color, C1 is the color of the first element, C1a is the alpha of the first element, C2 is the second element color, C2a is the alpha of the second element. The destination alpha is calculated with:
+ 
+ Da = C1a + C2a * (1 - C1a)
+ The resultant color is premultiplied with the alpha. To restore the color to the unmultiplied values, just divide by Da, the resultant alpha.

+from http://jira.red5.org/confluence/display/docs/Ping:
+
+Ping is the most mysterious message in PILI_RTMP and till now we haven't fully interpreted it yet. In summary, Ping message is used as a special command that are exchanged between client and server. This page aims to document all known Ping messages. Expect the list to grow.
+
+The type of Ping packet is 0x4 and contains two mandatory parameters and two optional parameters. The first parameter is the type of Ping and in short integer. The second parameter is the target of the ping. As Ping is always sent in Channel 2 (control channel) and the target object in PILI_RTMP header is always 0 which means the Connection object, it's necessary to put an extra parameter to indicate the exact target object the Ping is sent to. The second parameter takes this responsibility. The value has the same meaning as the target object field in PILI_RTMP header. (The second value could also be used as other purposes, like RTT Ping/Pong. It is used as the timestamp.) The third and fourth parameters are optional and could be looked upon as the parameter of the Ping packet. Below is an unexhausted list of Ping messages.
+
+    * type 0: Clear the stream. No third and fourth parameters. The second parameter could be 0. After the connection is established, a Ping 0,0 will be sent from server to client. The message will also be sent to client on the start of Play and in response of a Seek or Pause/Resume request. This Ping tells client to re-calibrate the clock with the timestamp of the next packet server sends.
+    * type 1: Tell the stream to clear the playing buffer.
+    * type 3: Buffer time of the client. The third parameter is the buffer time in millisecond.
+    * type 4: Reset a stream. Used together with type 0 in the case of VOD. Often sent before type 0.
+    * type 6: Ping the client from server. The second parameter is the current time.
+    * type 7: Pong reply from client. The second parameter is the time the server sent with his ping request.
+    * type 26: SWFVerification request
+    * type 27: SWFVerification response

+	 * The server meters its output so that data arrives at the client
+	 * in realtime and no faster.
+	 *
+	 * The rtmpdump program tries to set m_nBufferMS as large as
+	 * possible, to force the server to send data as fast as possible.
+	 * In practice, the server appears to cap this at about 1 hour's
+	 * worth of data. After the server has sent a complete buffer, and
+	 * sends this BufferEmpty message, it will wait until the play
+	 * duration of that buffer has passed before sending a new buffer.
+	 * The BufferReady message will be sent when the new buffer starts.
+	 * (There is no BufferReady message for the very first buffer;
+	 * presumably the Stream Begin message is sufficient for that
+	 * purpose.)
+	 *
+	 * If the network speed is much faster than the data bitrate, then
+	 * there may be long delays between the end of one buffer and the
+	 * start of the next.
+	 *
+	 * Since usually the network allows data to be sent at
+	 * faster than realtime, and rtmpdump wants to download the data
+	 * as fast as possible, we use this RTMP_LF_BUFX hack: when we
+	 * get the BufferEmpty message, we send a Pause followed by an
+	 * Unpause. This causes the server to send the next buffer immediately
+	 * instead of waiting for the full duration to elapse. (That's
+	 * also the purpose of the ToggleStream function, which rtmpdump
+	 * calls if we get a read timeout.)
+	 *
+	 * Media player apps don't need this hack since they are just
+	 * going to play the data in realtime anyway. It also doesn't work
+	 * for live streams since they obviously can only be sent in
+	 * realtime. And it's all moot if the network speed is actually
+	 * slower than the media bitrate.
