server looks too thin... in addition, the support for Qt files has been introduced since Real Server 8.0, which makes Darwin's prospects more unfavorable.However, we still need to see that Darwin has very wide restrictions on user authorization, and now DARwIn server is free and open source code, which gives developers a larger development space. so from the perspective of free software, this server software is already outstanding and crazy... in addition, the server not only supports mov files
fastest growing and most widely used video communication format. Based on the compression algorithm developed by Sorenson
. The FLV format is not only easy to import to flash, but also extremely fast, and can protect copyright, and can play videos without using a local Microsoft or Real Player.
Common video encoding:

Click the "set" button in the main window to enter the Advanced Settings dialog box, 2.In the video encoding Settings dialog box, the most significant one is the FLV video quality settings. The default value is "Flash 8-medium quality (400 Kbps)". The software has seven built-in encoding settings. You can also select custom settings and click the "show Advanced Settings" but

FLV is the short name of Flash video, FLV streaming media format is a new video format, all called Flash video. Because it forms a very small file, loading speed is very fast, so that the network to watch video files become possible, it has effectively solved the video file import Flash, so that the export SWF file size, can not be good use of the network and other shortcomings
FLV is the introduction of Flash MX with the development of video format, is currently used by many new generation of
Finalcut Pro, Apple QuickTime Pro, Avid Xpress DV, discreet Cleaner, Discreet Cleaner xl.
Here, take the most common player software QuickTime Pro for example:
First open the video file you want to convert in QuickTime Pro.
Then select the Output option in the File menu, locate the FLV in the file type of the dialog box that appears, and determine the location and name of the build file save.
The output settings including video stream, audio stream and file size are then converted.
Note
streaming server, data flow in the way from the flash Communication Server transfers, embeds video in SWF and plays on the timeline. Here, we select the first one, and then click Next to continue.

In the Encoding dialog box, we can set up how to configure the video encoding, and the system presets seven encoding profiles to accommodate different playback requirements. Click the Show Advanced Settings button to open the advanced settings for the video file, as shown in Figure 3. In the

In fact, some companies are already doing this (and have been doing it for a long time). Player is an excellent Flash Player. Later, it began to support H5. Below are some of its introduct
Video refers to a series of static images continuous image changes per second more than 24 frames (frame) screen above, according to the principle of visual persistence, the human eye can not identify a single static picture; Looks like a smooth, continuous visual effect.

In general==========There are planar and packed modes.- Planar mode means: You have 3 separate images, one for each component,each image 8 bits/pixel. To get the real colored pixel, you have tomix the components from all planes. The resolution of planes may differ!- Packed mode means: you have all components mixed/interleaved together,so you have small "packs" of components in a single, big image.There are RGB and YUV colorspaces.- RGB: Red, Green and Blue components. Used by analog VGA monitors
