OK, I will check it. But it seems there is a bigger, unacceptable problem. It came out during watching movie at nigth. There is very big delay between movie on the TV and captured frame: ~1-1.5s. UTV007 with old hyperion was much, much faster. I don't know why this happens and what fails: hyperion-ng, mjpg processing, that device or USB2.0 speed is insufficient. I didn't found 'frame decimation' option in hyperion-ng that was present in the previous generation . CPU has 30-40% usage for PAL, size decimation = 8 . I dont have a plan to upgrade my config to Rpi4 because there are problems with SPI. So it seems it's a dead end.
