 # This intermittently fails on Android due to async image decoding (bug #685516)

 # Sometimes the image decodes in time and the test passes, other times the image

 # appears blank and the test fails. This only seems to be triggered since the

 # switch to 24-bit colour (bug #803299).

 # webcam-simulacrum.mjpg is a hand-edited file containing red.jpg and blue.jpg,

 # concatenated together with the relevant headers for

 # multipart/x-mixed-replace. Specifically, with the headers in

 # webcam-simulacrum.mjpg^headers^, the web browser will get the following:

 #

 # HTTP 200 OK

 # Content-Type: multipart/x-mixed-replace;boundary=BOUNDARYOMG

 # 

 # --BOUNDARYOMG\r\n

 # Content-Type: image/jpeg\r\n

 # \r\n

 # <contents of red.jpg> (no newline)

 # --BOUNDARYOMG\r\n

 # Content-Type: image/jpeg\r\n

 # \r\n

 # <contents of blue.jpg> (no newline)

 # --BOUNDARYOMG--\r\n

 # 

 # (The boundary is arbitrary, and just has to be defined as something that

 # won't be in the text of the contents themselves. --$(boundary)\r\n means

 # "Here is the beginning of a boundary," and --$(boundary)-- means "All done

 # sending you parts.")
