fix crash issue because of high memory usage

 - The memory usage is high because of the invalid 'has_b_frames' value.

   The invalid 'has_b_frames' makes the condition in line #1239 false
   and 'h264_select_output_frame()' can't set the output frame in line #1241.
   So 'avcodec_receive_frame()' return the error(-11) due to no output frame.
   'avformat_find_stream_info()' try decode frame repeatly.
   As the result, the internal buffer for decoding is raised
   in 'avformat_find_stream_info()'.

 - We applied the patch from ffmpeg.
