input_gc2035.so

input_gc2035.tar.gz

mjpg-streamer의 input_uvc.so는 YUV만 지원하고, Orange PI PC2의 카메라인 GC2035는 YUV420코덱만 지원하기 때문에, mjpg-streamer에서 사용 할 수 없습니다.

제가 작업한 GC2035의 YUV420코덱을 지원하는 so 파일을 공개 합니다.
Orange PI PC2의 카메라인 GC2035를 사용해서 mjpg-streamer로 스크리밍 하시려면 첨부한 파일을 사용하세요.

pi@bpi-iot-ros-ai:~$ sudo fdisk /dev/mmcblk0

Welcome to fdisk (util-linux 2.27.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.


Command (m for help): p

Created a new partition 2 of type 'Linux' and of size 14.4 GiB.

Command (m for help): w
The partition table has been altered.
Calling ioctl() to re-read partition table.
Re-reading the partition table failed.: Device or resource busy

The kernel still uses the old table. The new table will be used at the next reboot or after you run partprobe(8) or kpartx(8).

Spring - Drag & Drop 파일 업로드 (img_type, img_id 속성 추가)

한 페이지내에서 여러개의 파일 업로드를 구현하기 위해서 img_type, img_id 속성을 추가해서 여러개의 업로드가 발생하더라고 구분 할 수 있게 구현

html 페이지

<div class="dragAndDropDiv" img_type="uploadarea" img_id="1">
<div class="dragAndDropDiv" img_type="uploadarea" img_id="2">

파일 올려진 경우 이벤트에서 img_type, img_id 속성 가져오기 - javascript

	$(document).on("drop",".dragAndDropDiv",function(e){
		$(this).css('border', '2px dotted #0B85A1');
		e.preventDefault();
		var files = e.originalEvent.dataTransfer.files;
		
		// img_type, img_id 속성 가져오기
		var img_type = $(e.target).attr('img_type');
		var img_id = $(e.target).attr('img_id');
		
		handleFileUpload(img_type, img_id, files,objDragAndDrop);
	});

FormData 구성 img_type, img_id 포함 - javascript

	function handleFileUpload(img_type, img_id, files,obj) {
		for (var i = 0; i < files.length; i++) {
			var fd = new FormData();
			fd.append('img_type', img_type);
			fd.append('img_id', img_id);
			fd.append('file', files[i]);
			
			var status = undefined;
			//var status = new createStatusbar(obj); //Using this we can set progress.
			//status.setFileNameSize(files[i].name,files[i].size);
			sendFileToServer(fd,status);
		}
	}

업로드 완료 처리 - javascript

img_type이 request인 경우 img테그의 src 속성 값 변경 처리

function sendFileToServer(formData,status) {
	var uploadURL = "<c:url value="/dragdrop/fileUpload/post.do"/>"; //Upload URL

... 생략 ...

		data: formData,
		success: function(data) { // 업로드가 완료되면 호출되는 메소드
			if (status != undefined) {
				status.setProgress(100);
			}
			
			// 
			console.log('img_type = ' + data.img_type);
			console.log('img_id = ' + data.img_id);
			$.each(data.files, function(index, file) {
				console.log('filename = ' + file);
				
				if (data.img_type=='request') {
					var targetObj = $(".dragAndDropDiv[img_type='"+data.img_type+"'][img_id='"+data.img_id+"']");
					targetObj.attr('src', '/test/' + file);
					targetObj.attr('uuid', file);
				}
			});
		}
	});
