Image/leds lagging on orange pi

  • Hello, when I run hyperiond with v4l2 grabber setting, it is lagging leds - jerky colors are generated. But when I run hyperiond without v4l2 setting and then I run hyperion-v4l2, then colors are nice. Any idea what is causing it? (and how to solve it?)


    Many thanks.


    OS: armbian, orange pi zero

  • here is my config:

  • frame/size Decimation did not help - colors are jerky. But when I use separate hyperiond and hyperion-v4l2, colors are great.
    spidev1.0 is there because OPi0 has LEDs on this output.

  • absolutelly sure my friend. Options are the same in both cases. Just behaviour is not the same as I described. :( This behaviour is quite interesting for me, too. What I found out is, that when hyperiond use grabber settings, it runs in one CPU core, but when I use separate hyperiond and v4l2 they use 2 cores (in one is hyperiond in second v4l2). But I tried to leave ON just one cpu core and even when they both used the same core, when running separately everything is ok, but when runningg via hyperiond jerky colors again.

  • yes, sure. they are uncommented when testing just with hyperiond. When testing with separate hyperiond a v4l2, I am removing it and parsing all commands to command line for hyperion-v4l2.

  • Code
    hyperion-v4l2 --device /dev/video0 --video-standard PAL --input 0 --width 720 --height 576 --crop-top 2 --crop-bottom 2 --crop-left 2 --crop-right 2 --frame-decimator 1 --size-decimator 1 --red-threshold 0.2 --green-threshold 0.4 --blue-threshold 1.0 --priority 900


    (with any frame/size decimation, width/height this works ok)
