Openrtmfp/Cumulus development Note (5) Playing cumulus real-time video streams

1. Define a window class:

Package

{

ImportFlash. display. Sprite;

Public class
LayerExtendsSprite

{

// Window layer

Protectedvar
_ Windowlayer: SPRITE;

Publicfunction
Layer ()

{

Init ();

}

Privatefunction
Init ():Void

{

_ Windowlayer =NewSprite ();

Addchild (_ windowlayer );

}

/**

* Window layer

*/

Publicfunction
GetWindowlayer (): Sprite

{

Return_ Windowlayer;

}

}

}

2. Declare a container variable:

Private var_container: SPRITE;

3. assign a value to the container variable:

PublicfunctionSetcontainer (container: SPRITE ):Void{

_ Container = container;

}

4. Play a video:

PublicfunctionPlayvideo ():Void
{

Buf. resetvideo ();

VaRVideo: Video =New
Video ();

Video. attachnetstream (BUF. NS );

_ Container. addchild (video );

}

Note: Buf is a custom video processing class, which requires the relevant netstream member variable. It is processed when a frame-by-frame video data is received, usage method _ ns. appendbytes (videoframe. streamdata );

Play the received real-time video frame, and the video class is mainly used to display the video, that is, the method video. attachnetstream (BUF. NS); the video class is associated with the relevant netstream

5. generally, the received video frame data does not contain the FLV Header Format, while the video data in the FLV format needs to be played in ActionScript. Therefore, the FLV header information must be added to the video, as follows:

VaRFirsttag: bytearray =New
Bytearray ();

Firsttag. endian = endian. big_endian;

// Video

Firsttag. writebyte (0x09 );

Firsttag. Position = 11;

// 4 bits: type of frame 1 => key frame + 4 bits: codecid 7 => AVC

Firsttag. writebyte (0x17 );

// Avcpackettype 0 => AVC sequence Header

Firsttag. writebyte (0x00 );

// Composition time, 3 bytes 0 for the firsttag

Firsttag. writebyte (0x00 );

Firsttag. writebyte (0x00 );

Firsttag. writebyte (0x00 );

// Todofirsttag. writebytes (avccfg );

VaRFirsttaglen: uint = firsttag. length;

Firsttag. writeunsignedint (firsttaglen );

Firsttag. Position = 1;

// 3-byte datasize

Firsttag. writebyte (firsttaglen-11)> 16) & 0xff );

Firsttag. writebyte (firsttaglen-11)> 8) & 0xff );

Firsttag. writebyte (firsttaglen-11) & 0xff );
