[FFmpeg-devel] how to disable loop filter for h264

[tp hm]

Hi
  I just downloaded the latest libavcodec, It seems like it is slower than a previoius version for decoding h264 video, is it possible to disable loop filter to speed up a little bit? how to do it ? 
  is it during initialization function:
     avcodec_open(pCodecCtx, pCodec), 
  ???
  because there is a flags in pCodecCtx that seems to  afftet the loop filter parameter in X264_init(AVCodecContext *avctx),
  or any other way to speed up h264 decoding?
