Thank you all,

I enable libx264 (--enable libx264 )in my configure options and it works.
But I have an other question.
I know that the function used to encode picture in h263 is  static int
encode_picture(MpegEncContext *s, int picture_number)
located at  ffmpeg/libavcodec/mpegvideo_enc.c file. Correct me if I mistake.
Then can someone tell me the funtion used to encode picture for h264 and
the file in which I can find this function , please?
