아직까지는 찾지를 못함..

직접 구현해야 하려나?

M-JPEG over HTTP

HTTP streaming separates each image into individual HTTP replies on a specified marker. RTP streaming creates packets of a sequence of JPEG images that can be received by clients such as QuickTime or VLC.

In response to a GET request for a MJPEG file or stream, the server streams the sequence of JPEG frames over HTTP. A special mime-type content type multipart/x-mixed-replace;boundary=<boundary-name> informs the client to expect several parts (frames) as an answer delimited by <boundary-name>. This boundary name is expressly disclosed within the MIME-type declaration itself. The TCP connection is not closed as long as the client wants to receive new frames and the server wants to provide new frames. Two basic implementations of a M-JPEG streaming server are cambozola and MJPG-Streamer. The more robust ffmpeg-server also provides M-JPEG streaming support.

VLC로 raw 덤프해서 보니...

--myboundary

Content-type: image/jpeg

이렇게 시작하고 그 아래로는 깨지는걸 봐서는 그냥 jpeg 프레임인듯..

심심..(?)해서 저기 MIME 관련 헤더들 삭제하고 jpeg으로 저장하니

아래와 같이 똮!

저장을 좀 오래 하니

--myboundary

Content-type: image/jpeg

가 반복적으로 나타난다.

video/x-jpeg

Motion-JPEG video.

There are currently no specific properties defined or needed for this type. Note that video/x-jpeg only applies to Motion-JPEG pictures (YUY2 colourspace). RGB colourspace JPEG images are referred to as image/jpeg (JPEG image).
