EIS, OIS, gimbal, or post-process video

In my YouTube "Nomad" series, I record a lot of videos while walking. When I purchased my Moto G75, the OIS (Optical Image Stabilization) feature was one of the deciding factors. There is some jerkiness when walking, and I suppose the OIS helps; however, when panning, which I do a lot, there is a jerkiness that is actually caused by the OIS.

I asked Google about this:

Panning shots: Sometimes internal stabilization fights a smooth pan and creates a jerky snap at the end of the movement.

Well, no, not at the end of the pan, I get it 2 or 3 times during a large pan. Google AI also stated this:

Using a tripod: Keeping stabilization on while the camera is completely still can cause small, unwanted floating or jumping motions. Turn it off for tripod shots.

I have been experimenting with video post-processing stabilization apps, but they don't make the videos better.

Watching YouTube videos, it seems that top-brand action cameras can track an object, such as a face, and record very un-jerky videos. Or, use a 3-axis gimbal, either a camera with integrated gimbal, or one to which a phone can be attached. Latter example:

...main problem is they are large. When I travel, want recording to be as discrete as possible.

Or, combined camera and gimbal, such as the DJI Osmo Pocket:

...AU$789!!!

No, not ready to throw money at something like that. Not yet anyway. Still one more thing to try with my phone; record with OIS turned off, then post-process.  Will give that a go tomorrow.

To follow the progress, here is my "Nomad" video series:

Improve low-battery warning

Easy 7.4.7 has powerapplet_tray version 3.1, which added a beep when battery discharges below 10%, repeated every 15 seconds (and only when discharging, not on charge).

One of the tester guys commented that it wasn't very noticeable, and unfortunately I also discovered the same. Running the laptop in my tent, it wasn't on charge, and I did hear the beep, but didn't connect that with the battery being low. The tray icon also flashes, but I didn't notice that either. Then the laptop suddenly died.

I have bumped powerapplet_tray to version 3.2, and this time it calls an external script, /usr/sbin/bat-low-warn, every 15 seconds:

#!/bin/ash
#20260827 /root/Startup/powerapplet_tray will call this every 15 seconds
#when battery below 10%.

export TEXTDOMAIN=bat-low-warn
export OUTPUT_CHARSET=UTF-8

paplay /usr/share/audio/error.wav

M0="$(gettext 'WARNING LOW BATTERY')"
popup "background=#ffa0a0 terminate=5 timecount=dn name=batlow|<big><big><b>${M0} </b></big></big>"

sleep 1
paplay /usr/share/audio/error.wav
###end###

...that should get our attention!

Phone signal in tent

Ha ha, this is funny. I have been camping here for two weeks, at a campground on the south coast of Western Australia, and had to walk about 5 minutes to the beach to get a phone signal.

Wasn't getting a signal in my tent; however, today discovered if raise my phone, and get it into just the right spot, there is a weak 4G signal:

It is weak, some websites timeout, but can do basic browsing with phone a wifi hotspot; gmail and forum access ok. The signal may be dependent on the weather, we shall see.

EasyOS draft submitted to Wikipedia

Forum member pp4mnk submitted this to Wikipedia awhile ago:

https://en.wikipedia.org/wiki/Draft:EasyOS

I didn't mention it earlier, as I thought that it looked OK and would be accepted. But it hasn't, see the commentary prepended.

pp4mnk sent me this in a private message, June 26:

I consider positive if easyos users can visit it and make suggestions to improve it, but they must take into account wikipedia basics, so a post publishing that I have prepared a Wikipedia draft, and it is currently awaiting review. If anyone would like to take a look and notices any errors, references that could be improved, or sections that could be made more neutral, I would be greatly appreciate any suggestions. https://en.wikipedia.org/wiki/Draft:EasyOS

Many people think Wikipedia has very few restrictions, but it's actually quite the opposite. The standards are very strict, and depending on which reviewer evaluates your draft, getting it accepted can sometimes be quite challenging. Let's keep our fingers crossed!

I greatly appreciate the effort that pp4mnk has put into this. Maybe someone could edit it, take out what they consider to be LLM-generated.

Fix for pulseaudio causing app crash

Described this earlier today:

https://bkhome.org/news/202608/pulseaudio-mixer-causes-apps-to-crash.html

I'm concerned that apps other than geany might also crash, and apps other than pavucontrol might cause the crashes.

So, have restored this in /etc/profile:

export XLIB_SKIP_ARGB_VISUALS=1

As was described in a github link in the previous blog post, enabling that variable causes issues with Asian languages in chromium. So, instead have disabled it in chromium.

/usr/bin/chromium is a script, that will run chromium as user "chromium". I have inserted this into the script:

unset XLIB_SKIP_ARGB_VISUALS

The script is generated by /usr/local/clients/setup-client, by woofQ2 when EasyOS is built.

Interesting, I wonder if some other mysterious crashes that some users have reported, will now be fixed.

Pulseaudio mixer causes apps to crash

Forum members vtpup and NorthernSoul have reported the problem:

https://forum.puppylinux.com/viewtopic.php?p=175677#p175677

Look in /etc/profile:

#20230918 remove... ref: https://github.com/puppylinux-woof-CE/woof-CE/pull/3867
##v2.10 MU: rox crashes with DRI modules. solution:
#export XLIB_SKIP_ARGB_VISUALS=1

That link:

https://github.com/puppylinux-woof-CE/woof-CE/pull/3867

That variable was unset due to Chromium unable to properly display Chinese and other Asian characters if it is set.

I'll think about it, but probably won't set it globally, just set it when run 'pavucontrol', as the guys have suggested.

More packages compiled in woofQ2

Just to let you guys know, I'm still working on EasyOS; currently compiling packages in woofQ2.

The Excalibur-series is built with a lot of binary packages from the Scarthgap-series. Scarthgap is built with binary packages compiled in OpenEmbedded/Yocto, and there are a lot that are not available in the Devuan/Debian repositories. Hence, those binary packages have been used to build the Excalibur-series. But, I am gradually porting them into woofQ2, so they will be compiled in a running Easy Excalibur.

Doing the nomad thing right now, and likely for sometime into the future, so at times won't have Internet access. Right now where I'm camping, don't have a phone signal, but do have one nearby. A five minute walk, where I am right now.
