http://192.168.x.x:8080/?page=snapshot

I hope that @roleoroleo can grab the Hisilicon model at some point and compile an app that will read directly from the kernel (at least that was roleo's plan at some point)
Anyone would like to donate a device?
Yes, I could try it. But probably with a swap file you can solve the problem.
I already have a swap file on my device as it is recommended, it doesn't help :-/. I have change my SD Card too without any Success.
Please check if the swap file is really enabled. Your top command is doubtful.
It seems really enabled :

@roleoroleo do you think that Swap is not utilised enough to manage the memory allocation? I find the same on yi_dome where Swap has minimal usage even the main memory is almost fully used.
Maybe some proc parameter. For example, what's the value of swappiness?
cat /proc/sys/vm/swappiness
I changed it to 60 to see the difference
/home/yi-hack-v5 # echo 60 >> /proc/sys/vm/swappiness
/home/yi-hack-v5 # cat /proc/sys/vm/swappiness
60
/home/yi-hack-v5 # reboot
Probably there is a line that forces this value during the boot. init.sh or other startup scripts. If you reboot it will come back to 0.

Correct, it was 0, I am changing it to the following:
sysctl -w vm.dirty_background_ratio=2
sysctl -w vm.dirty_ratio=5
sysctl -w vm.dirty_writeback_centisecs=100
sysctl -w vm.dirty_expire_centisecs=500
sysctl -w vm.vfs_cache_pressure=200
sysctl -w vm.swappiness=40
echo 5 > /proc/sys/vm/laptop_mode
echo 60 > /proc/sys/vm/swappiness
It works - it took 14 seconds for a snapshot but no hanging anymore. It could resolve many issues moving forward. I tested it with the v0.3.1 so before even your commits addressing memory allocation.
Thanks @roleoroleo

Took around 15s to get high res snapshot. Seems really better. Thx ! Done on 0.3.1 BETA. Load still around 6, but camera works great.

Can confirm this on my 6CUS camera as well. The high quality snapshot now works, even if it takes a little while.
Same for YI Outdoor 4CUS. Swap was enabled but not used without this extra sysctl settings.

Excuse me but.. How to edit this .sh file ? A mean, what is the command ? :/
You can use default shell editor vi - it's difficult at start but it's doable.

Doesn't seem to work for me... added a couple of those lines but the rstp feed is never accessible from vlc or any other app.
