I want to watch fixed display size from movie file. (eg. 640x480)
 I'm trying to use img_resample function.
 I don't know what i do before calling img_resample_init function.
 something following line.
if(packet.stream_index == m_nVideoStream)
// decoding next frame.
bytesDecoded = avcodec_decode_video(m_pCodecCtx, m_pFrame, &frameFinished, 
packet.data, packet.size);

 img_convert((AVPicture *)m_pFrameRGB, PIX_FMT_RGB24, (AVPicture*)m_pFrame,
m_pCodecCtx->pix_fmt, m_pCodecCtx->width, m_pCodecCtx->height); // m_pFrame 
has YUV frame 
 ImgReSampleContext *s;
s = img_resample_init( 640, 480, width, height); // initialize resample
img_resample(s, m_pic, (AVPicture *)m_pFrameRGB); // error occur
