This allows a novel method to do\non-the-fly live editing of captured video and audio. This also removes the need for editing software or editing skills.\nthe only requirement is to include an agreed QR code image into the slides or to be displayed on camera.\n\nThings to note\n--------------\n\nQR codes have up to 30% error correction redundancy, for real world application its worth considering a high-redundnacy\nQR code image being used with this plugin. http://blog.qrstuff.com/2011/12/14/qr-code-error-correction\n\nUse of this plugin is optimised with mono-stream video of the slides. using a camera or FMV may have an impact on recording\nperformance (hardware dependant). Its worth looking at the QRcode config options ``rescale``, ``drop_frames`` and ``buffers``\nto help tune performance.\n\nUsing this plugin to do the editing on the Opencast server was planned but not implemented therefore the options\n``mp_add_edits`` and ``mp_add_smil`` are best left as ``False``\n\nLoading\n-------\n\nTo activate the plugin, add the line in the `plugins` section of your configuration file\n::\n\n    [plugins]\n    qrcode = True\n\nTrue: Enables plugin.\nFalse: Disables plugin.\n\nAnd set the recording pipeline pause type\n::\n\n    [recorder]\n    pausetype = recording\n\nrecording: GST pipeline keeps running, nothing recorded when paused.\n\nQR code example:\n----------------\n\n``pause``\n\n.. image:: docs/pause.png\n\nPlugin Options\n--------------\n::\n\n    [qrcode]\n    pause_mode = hold\n    hold_code = pause\n    stop_code = stop\n    start_code = start\n    rescale = 640x360\n    mp_add_edits = False\n    mp_force_trimhold = False\n    mp_add_smil = False\n    drop_frames = True\n    buffers = 200\n    hold_timeout = 1\n    ignore_track_name
