I call under the unity android so generated by the studio, so it calls the MediaCodec decoding H264 get picture
But the unity is rgba texture format
I like write the conversion speed is very slow
MediaCodec can directly output RGBA
The transformation code is as follows:

 
Void FillDispData (int * pdstRgba, int len) 
{
int x,y; 
Unsigned int * PDST [2]; 
Unsigned char * psrcY [2]. 
Unsigned char * psrcUV; 

If (nOutCnt==nInCnt) 
{
//LOGD (" NO DATA "); 
return; 
} 
NOutCnt=nInCnt; 
//pthread_mutex_lock (& amp; Mutex); 
//yuv2rgb 
If # 1 
PsrcY [1]=yuv; 
PsrcUV=yuv + 1920 * 1080; 
For (y=0; Y<1080; Y +=2) 
{
PDST [0]=(unsigned int *) & amp; PdstRgba [(1078 -) y * 1920]; 
PDST [1]=PDST [0] + 1920. 
PsrcY [0]=psrcY [1]. PsrcY [1] +=1920; 
For (x=0; X<1920; X +=2) 
{
Int, u, v, y [4], I; 
Int rx, gx, bx, r, g, b. 
U=* psrcUV++; V=* psrcUV++; 
Gx=((u - 128) * 88 & gt;> 8) - ((v - 128) * 183 & gt;> 8); 
Rx=(v - 128) + ((v - 128) * 103 & gt;> 8); 
Bx=(u - 128) + ((u - 128) * 198 & gt;> 8); 
Y [0]=* psrcY [0] + +; Y [1]=* psrcY [0] + +; 
Y [2]=* psrcY [1] + +; Y [3]=* psrcY [1] + +; 
for(i=0; i<4. I++) 
{
R=y [I] + rx. 
If (r> 255) r=255; 
Else if (rG=y [I] + gx; 
If (g> 255) g=255; 
Else if (gB=y [I] + bx; 
If (b> 255) b=255; 
Else if (b* PDST [I/2] + +=0 xff000000 | (b<16) | (g<8) | r; 
} 
} 
} 
# endif 
//pthread_mutex_unlock (& amp; Mutex); 
}
