Hi,
Anyone have tried to flip the usb camera inside the conf file of camera streamer?
I've successfully connected both usb cameras and one of them need to be flipped vertically. I've managed to do so in multicam plugin, also managed to see the rotated image in homeassistant - BUT when tried to send image via Telegram bot (each 15min) still I receive image which is not rotated (understood cause changes are made only in GUI). Nevertheless I've tried to done it in .conf file tried many combinations, search this forum, searched other forums and nothing was helpful.
