@bite_your_idols random thought: changing v4l parameters might fail if hyperion is accessing the /dev/video device - have you tried stopping hyperion before that?

Also you seem to be running the "official" hyperion version, not the LE addon version - have you tried using the hyperion addon from the LE repository instead?

I'm using hyperion with the dispmanx grabber, previously the precompiled version from hyperion and since some time the LE addon version - didn't have any issues so far with any of that in 8.2 and milhouse builds.

so long,
