Hi,
SwsContext* imgConvertCtxYuv420pToRGB24 = 0;
...
if( !p_imgConvertCtxYuv420pToRGB24 )
{
imgConvertCtxYuv420pToRGB24 = sws_getContext( p_codecCtx->width,
p_codecCtx->height, p_codecCtx->pix_fmt,
p_private->p_codecCtx->width, p_private->p_codecCtx->height,
PIX_FMT_RGB24, SWS_BICUBIC, NULL, NULL, NULL );
}
...
// get and decode the frame
...
sws_scale( imgConvertCtxYuv420pToRGB24 ,
p_Frame->data, p_Frame->linesize, 0, p_codecCtx->height,
p_FrameRGB24->data, p_FrameRGB24->linesize );
That's it.
Chris.

Objet : [libav-user] Conversion yuvj420P to RGB24
Hi,
I need to display a frame from an IP Camera stream in RGB24 format. However,
I have found out that the format of the frame is in YUVJ420P but I need to
display in RGB24. When using sws_getContext and swscale, all I get is a
green screen filled with noise.
Does anybody know how I can make this conversion work?
Thank you
Candice
