[chetan shawroop]

hi 

 I am trying to use  sws_scale from ffmpeg as suggest by you for conversion from ARGB to YUV format  .i download the ffmpeg-20130327-git-81e85bc-win32-dev.7z from ffmpeg

include the header file and lib "swscale.lib  swresample.lib" but compilor unable to resolve the related function of  swcale.lib . i am getting the following error

1>ffmpeg.obj : error LNK2019: unresolved external symbol "struct SwsContext * __cdecl sws_getContext(int,int,enum PixelFormat,int,int,enum PixelFormat,int,struct SwsFilter *,struct SwsFilter *,double const *)" (?sws_getContext@@YAPAUSwsContext@@HHW4PixelFormat@@HH0HPAUSwsFilter@@1PBN at Z) referenced in function _wmain
1>C:\Users\chetan\Desktop\New folder\ffmpeg\Debug\ffmpegtest.exe : fatal error LNK1120: 1 unresolved externals

Hi Friend's
       I am using x264 Encoder in my application .I am getting raw ARGB Data as input from some source .i want  to encode that data using x264 Encoder .i know the some of the attribute of my input like height,width, framerate etc.  

 
int iframe_size = x264_encoder_encode(    m_pEncoder, 
                                                                &m_nals, 
                                   
                             &i_nals, 
                                                                &m_pic_in, 
                                                                &m_pic_out);    //number of output NAL

That's very basic question. You should read some documentation at least for the basics. 
In order to feed this data to x264, you need to convert it to YUV420 format. For this, you may use swscale API coming along with ffmpeg. There are some others as well.

Good luck.
