I encountered the same issue. I wrote my solution here. It involves manually editing the system.sh file in the sdcard in the yi-hack-v5/script folder, so I only advise doing it if you feel comfortable editing it. You can take out the sdcard or edit it through ftp by accessing /tmp/sd. A restart will be required.

Find the DISABLE_CLOUD sections (should begin line 165) and replace it with this:

if [[ $(get_config DISABLE_CLOUD) == "no" ]] ; then
    (
        cd /home/app
        killall dispatch
        LD_PRELOAD=/home/yi-hack-v5/lib/ipc_multiplex.so ./dispatch &
        sleep 3
        if [[ $(get_config TIME_OSD) == "yes" ]] ; then
            echo -ne '\x01\x00\x00\x00' | dd of=/tmp/mmap.info bs=1 seek=0 count=4 conv=notrunc
        fi
        LD_LIBRARY_PATH="/home/yi-hack-v5/lib:/lib:/home/lib:/home/app/locallib:/home/hisiko/hisilib" ./rmm &
        sleep 8
        ./mp4record &
        ./cloud &
        ./p2p_tnp &
        if [[ $(cat /home/app/.camver) != "yi_dome" ]] ; then
            ./oss &
        fi
        ./watch_process &
    )
fi
if [[ $(get_config DISABLE_CLOUD) == "yes" ]] ; then
    (
        cd /home/app
        killall dispatch
        LD_PRELOAD=/home/yi-hack-v5/lib/ipc_multiplex.so ./dispatch &
        sleep 3
        if [[ $(get_config TIME_OSD) == "yes" ]] ; then
            echo -ne '\x01\x00\x00\x00' | dd of=/tmp/mmap.info bs=1 seek=0 count=4 conv=notrunc
        fi
        LD_LIBRARY_PATH="/home/yi-hack-v5/lib:/lib:/home/lib:/home/app/locallib:/home/hisiko/hisilib" ./rmm &
	sleep 8
        if [[ $(get_config REC_WITHOUT_CLOUD) == "yes" ]] ; then
            cd /home/app
            ./mp4record &
        fi
	sleep 4
        ./cloud &
    )
fi

There are many things to fix in the next pre-release.

PR is the quickest way, but the next pre-release will take me longer than expected.

New release - 0.4.1f

[Minims]

So i have tried on Yi Home 27US 0.4.1f and I have still no watermark :-(.
Testing on Outdoor.

[Minims]

The issue is still present on Yi OutDoor 9CUS. Cloud disable or not.

[alienatedsec]

I'll test it later too

[Minims]

I'm suspecting an issue with the sleep values and/or a process that is still alive and make the library load fails. But i can't confirm this.

[alienatedsec]

@roleoroleo any advice on how the OSD should be called to be rendered?

[roleoroleo]

It's probably a race condition.
If I remember correctly mmap.info should be changed between dispatch and rmm.
But not too early.
You should try to increase the sleep before to run rmm.

While trying to debug, i have this. Don't know if it is related to this issue :

/home/app #   LD_PRELOAD=/home/yi-hack-v5/lib/ipc_multiplex.so ./dispatch &
/home/app # insmod: can't insert '/home/app/localko/ssp_ms41909.ko': No such file or directory

[roleoroleo]

insmod: can't insert '/home/app/localko/ssp_ms41909.ko': No such file or directory

I think it's not related to the issue.

Dispatch is used to load kernel drivers dynamically and its likely to have different or even similar errors on other cameras.
