I'm newbie in ffmpeg.

my problem is "avcodec_find_encoder(CODEC_ID_H264);" func always returning null.

ffmpeg configure is below on my ubuntu system.

./ffmpeg
FFmpeg version SVN-r26306, Copyright (c) 2000-2011 the FFmpeg developers
  built on Jan 11 2011 10:34:49 with gcc 4.4.5
  configuration: --enable-gpl --enable-version3 --enable-nonfree --enable-postproc --enable-libfaac --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libxvid --enable-x11grab
  libavutil     50.36. 0 / 50.36. 0
  libavcore      0.16. 0 /  0.16. 0
  libavcodec    52.108. 0 / 52.108. 0
  libavformat   52.92. 0 / 52.92. 0
  libavdevice   52. 2. 3 / 52. 2. 3
  libavfilter    1.72. 0 /  1.72. 0
  libswscale     0.12. 0 /  0.12. 0
  libpostproc   51. 2. 0 / 51. 2. 0

as you can see, configuration contains --enable-libx264

so I think avcodec_find_encoder(CODEC_ID_H264); have to return something not null... please let me know how to solve this problem?

ps) when i compile my test program, using below

gcc -o test test.c -lavutil -lavformat -lavcodec -lx264 -lz -lm

thanks
