-- Test2Queue.doTest ----------------------------
body = Hello Camel
header1 = value1-1
header2 = value2
header3 = null
header4 = null
Hello Camel

설명

Camel에서 기본적으로 Header의 내용은 Queue 넘어 갈때 초기화 되는데,
초기화 하지 않고, 그대로 데이터를 가지고 다니려면 preserveMessageQos=true 해주면 된다.

출력결과를 보시면 알 수 있듯이 기본 자료형외에 객체는 전달 할 수가 없는 것으로 판단된다.

header1 : 초기에 전달된 Header의 값으로 그 값을 변경했을때 변경된 값이 전달되는 것을 확인
header2 : 초기에 전달되지 않았으나 추가로 Header에 추가된 값으로 Queue 이동 후 값이 존재하는 것을 확인
Header3 : ArreyList에 기본형 데이터(String) 추가해서 Header에 추가해서 전달했으나 List 전달되지 않는 것으로 확인
Header4 : 사용자가 임으로 만들 객체를 Header에 추가 했으나 Queue 이동 후 값이 전달되지 않는 것으로 확인

PHP - MYSQL 조회

출처 : Mysql_fetch_row 와 Mysql_fetch_array 차이

나누기 몫, 나머지

$num = floor(10 / 3); // 소수점 이하는 버리고 몫만 = 3
$num_1 = 10 % 3; // 나머지 = 1

echo "num = $num / num_1 = $num_1";

mysql_fetch_array : 필드이름으로 데이터 조회

<? 
$connect = mysql_connect('localhost', 'user id', 'password'); 
mysql_select_db("dbname", $connect); 

$query = "select userid, name, tel from user"; 
$result = mysql_query($query, $connect); 
$row = mysql_fetch_array($result);

PHP Inline IF

FMX.Types.TBitmap.Unmap

FireMonkey에서 FFMpeg를 이용해서 이미지 챕쳐 하는 부분을 구현했습니다.
기존에 데이터는 Bitmap의 픽셀단위로 복사해서 구현했는데,
TImageControl 컴포넌트의 Bitamp.TBitmapData에 바로 데이터를 쓰도록 하는 방법을 찾아서,
기존 코드에 불필요한 부분을 제거하고 다시 구현했습니다.

FireMonkey에서 FFMpeg 사용하는 부분도 간단하게 정리했습니다..

파일 포맷과 코덱을 라이브러리 등록

av_register_all();

동영상 파일 읽기

errnum := avformat_open_input(@fFormatContext, Edit1.Text, nil, nil);

스트림 정보 조회

errnum := avformat_find_stream_info(fFormatContext, nil);

비디오, 오디오 스트림 Index 찾기

  for i := 0 to fFormatContext.nb_streams-1 do
  begin
    Stream := PPAVStream(PtrUInt(fFormatContext.streams) + i * Sizeof(pointer))^;

    if (Stream.codec.codec_type = CODEC_TYPE_VIDEO) and
       (FirstVideoStream < 0) then
    begin
      FirstVideoStream := i;
    end;

    if (Stream.codec.codec_type = CODEC_TYPE_AUDIO) and
       (FirstAudioStream < 0) then
    begin
      FirstAudioStream := i;
    end;
  end;

Codec 찾기

fCodec := avcodec_find_decoder(fCodecContext^.codec_id);

Codec 열기

errnum := avcodec_open2(fCodecContext, fCodec, nil);

동영상 정보 출력

  Memo1.Lines.Add('Found a matching Codec: '+ fCodecContext^.Codec.Name + sLineBreak +
    sLineBreak +
    '  Width = '+inttostr(fCodecContext^.width) +
    ', Height='+inttostr(fCodecContext^.height) + sLineBreak +
    '  Aspect    : '+inttostr(fCodecContext^.sample_aspect_ratio.num) + '/' +
                     inttostr(fCodecContext^.sample_aspect_ratio.den) + sLineBreak +
    '  Framerate : '+inttostr(fCodecContext^.time_base.num) + '/' +
                     inttostr(fCodecContext^.time_base.den));

Bitmap 객체 생성, TBitmapData

    ImageControl1.Bitmap := TBitmap.Create(fCodecContext^.width, fCodecContext^.Height);
    ImageControl1.Bitmap.Map(TMapAccess.maWrite, FBmpData);

AVPicture 구조체에 TImageControl.Bitmap의 버퍼와 연결

  errnum := avpicture_fill(PAVPicture(fAVFrameRGB), FBmpData.Data, PIXEL_FMT_FFMPEG,
      fCodecContext^.width, fCodecContext^.height);

파일에서 데이터를 읽기

errnum := av_read_frame(fFormatContext, AVPacket);

디코딩된 YUV 데이터 얻기

avcodec_decode_video2(fCodecContext, fAVFrame, frameFinished, @AVPacket);

색상 공간 변환

errnum := sws_scale(fSwScaleContext, @fAVFrame.data, @fAVFrame.linesize,
                0, fCodecContext^.Height,
                @fAVFrameRGB.data, @fAVFrameRGB.linesize);

Finalizes the customizing session of the current bitmap.
