        ================
        
        `FLASk supported Http webCAM`
        
        IN DEVELOPMENT
        
        /Here, the merge of several ideas will form the package for easy
        installable webcam surveylance via PyPI. The basic aim is to access view
        to various technical devices during an experiment./
        
        Usage screen
        ------------
        
        ``` {.bash org-language="sh"}
        ... usage:
            flashcam ls
            flashcam getres [product | IDpath ]        # flashcam getres "Webcam C270"
            flashcam show ... show
            flashcam show  "Webcam C270"  -r 320x176
        
            flashcam flask & # (just a hint for gunicorn+wget)
            flashcam flask5000 [-w]   #  view on port 5000, immediatelly start browser tab
        
            flashcam savecfg [-a 11 ...]  # save cmdline parameters to congig for flask/gunicorn
        
        ..... advanced usage .... (accumulation, blur, threshold, frame_kind)
            flashcam show -a 19 -b 3 -t 100 -f [direct|delta|detect|histo]  [-h]  [-l 3600]
        
        ....  v4l setting .......... (exposure, gain  for automatically recommended video)
            flashcam v4l -e [auto | 0.0..1.0]  -g [0.0..1.0]
        
        ...... uninteruptable stream .....................
            flashcam uni http://192.168.0.91:8000/video  [-s ] # to save avi
        
        ```
        
        Typical usecase
        ---------------
        
        ### motion
        
        ``` {.bash org-language="sh"}
        # tune parameters with flask5000 or show; no parameter == default value
        # -w means - open web view
        flashcam.py flask5000  -w -l 1 -a 11 -b 11 -t 30
        # save config
        flashcam.py savecfg -l 1 -a 11 -b 11 -t 50
        # run server - ONE worker, many threads
        #    option flask should start wget with delay to start the camera
        flashcam.py flask& gunicorn --threads 5  -w 1 -b 0.0.0.0:8000  --timeout 15 web:app
        ```
        
        ### astro
        
        ``` {.bash org-language="sh"}
        #  x:- is compensate to right y:- is compensate to down;   -x -0.35  -y -0.015
        # repair broken AVI
        ls -1 *avi | xargs -n 1 -I III ffmpeg -i III -c:v copy -c:a copy repIII
        ```
        
        ### join many avi files from UNI
        
        ``` {.bash org-language="sh"}
        ls zen_192.168.0.91_* | while read line; do echo file \'$line\'; done | ffmpeg -protocol_whitelist file,pipe -f concat -i - -c copy output.avi
        
        ```
        
        Status:
        -------
        
        -   `usbcheck` can identify the camera by `product` or `IDpath`
        -   `v4l2` prove of concept - exposure/gain autotune - worked
        -   `show` (imshow) was tuned, now it needs a rewrite with `base_camera`
        -   `flask` interface is responsive
        -   `web.py` must be same with `flask5000` option
        -   `base_camera` (with greenlets) and `real_camera` modules work with
            flask
            -   initialized with `recommend`
            -   never-stopping (unlike the original version)
            -   more tricky tuning classmethod andstaticmethod was needed
        -   `flask` interface works
        -   gray frame is sent when no camera through web
        -   autostarts (threading) with `wget -u -p -O /dev/null` for 3 sec. and
            then kill
        -   properly taken `product` in `real_cam`
        -   rewrite proprerly for gunicorn (no gevent; --w 1 --t 5+); flashcam
            flask
        -   with automatic wget to start, with debugprint for gunicorn too
        -   !! `product` may not work now
        -   `stream_enhancer` decorations ON
        -   =detect motion basics ON -t threshold (0 - means NO)
        -   three modes -a 10 -b 3 -t 100 -f \[direct\|delta\|detect\]
        -   v4l commandline and in-image display works
        -   astro delta x,y per second works
        -   saving to \$HOME path
        -   `uni` option ... uninteruptable view, \'s\' to save \'q\' to quit,
            -s to save avi
        
        To see next
        -----------
        
        -   automatic exposure
        -   save jpg from web
        
        V4l2
        ----
        
        Camera sometimes needs to tune at dark conditions. Nicely done project
        to call `v4l2-ctrl` was used
        
        Identification of a camera
        --------------------------
        
        Several devices on USB, replugging or an built-in webcam of the notebok
        or sevral dev/video devices per CAM can make identification via
        `/dev/video` more difficult.
