I need to record "everything": Starting from the birds landing on the roof until the fligh away again. Since the camera delivers Full HD video AND I need the "complete movie" of the bird motion detection is not suitable here: Decoding analyzing and reencoding in case of recording would take to much horsepower... But Normally I will recogize the birds after the landed on the roof. My idea is to do something like loop recoording: The stream is cut into pieces of 5 minutes length. If I dont hit "ENTER" (or something similar) the previously recorded piece of video gets delted after the current one has been completly recorded. If I hit ENTER no deletion is performed until I hit ENTER again. I already have a script hacked together with a gst-launch command, which is able to fetch the Full HD hardware encoded stream from the C920 and put it on the harddisk. But I failed in creating a script which allows me to simultanously watch the material which gets recorded just in the same moment. Is there any software or script or which does this loop recording as described above AND is able to pull the Full HD stream correctly from the C920? Where can I proceed? Thank you very much in advance for any help! Best regards and have a nice weekend! mcc
