revid: MJPEG output from file

Saxon Milton

Now assigned to @Ella Pietraroia . Seems like this is not working. We are sending MJPEG wrapped in MPEG-TS to vidgrind but when we try to download the raw MJPEG, VLC is not happy to play. We don’t yet understand whether this is something happening to the video on the client side, or on the vidgrind side. It is suggested that (only for debugging) the recvHandler() function on videgrind is modified so that clips are received and mts.Extract is used to get “raw” MJPEG and then we write this raw MJPEG straight to a file. If this MJPEG is okay, then we know that revid is packetising the MJPEG okay and that for some reason downloading on videgrind isn’t working (which still could be something wrong with revid’s packetisation(probably timing related (PTS))).
