Hi chill, as with most things I do, my approach is a bit hacky but it's working pretty well. The basic operation (ignoring the mechanics of generating the image) is:
- Have jivelite configured to use image viewer as the screen saver, configuring the delay times as desired - I have separate http server running on my LMS server for other things already so I'm used that to serve the image list file and image(s) - Point jivelite to the url of the image list file (http://10.0.0.10/res/photos/photos.lst) - I have just a single entry in the image list file (http://10.0.0.10/res/photos/wx.png) - The wx.png file is actually a symlink to the real file which is in ram instead of on disk: wx.png -> /dev/shm/wxd/png/wx.png - I have a cron job on the server which runs every minute to regenerate the wx.png, every run it: updates the time updates the current temperature 3 times an hour on minutes 20,40, and 00 updates the 5 hour forecast at the bottom once an hour on minute 00 I'm pulling the weather data from a couple weather.gov sites (US) the forecast is json and the currect observation is a METAR text file. I was concerned that having a single file in the image list would result in image viewer just downloading it once and never updating it, but it looks like based on my server log, that image viewer downloads the list file and then runs through the list until it gets to the end and then starts again by starting the process over - so since my list only has the single entry, my log shows alternating requests, first for the list file, then for the image, then the list file, then the image, etc. over and over. And since jivelite does a bit of a fade between images, the minute changing actually looks pretty cool. I've still got some improvements I want to make to the image generation script, sort of thinking about rewriting it altogether to get rid of some of the heavier tools I'm using, like jq for the json file parsing. ------------------------------------------------------------------------ sodface's Profile: http://forums.slimdevices.com/member.php?userid=19057 View this thread: http://forums.slimdevices.com/showthread.php?t=111488 _______________________________________________ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
