Rebooted with it set to 256 and Chromium now plays videos properly.
It played videos fine, set at 64, before the upgrade; why would that change with the Chromium update?

Chromium ffmpeg displaying static instead of videos

About a month ago I updated and upgraded my Raspbian Stretch desktop to the latest package versions. Chromium was updated from version 65 to version 72. All videos played in the browser now look "scrambled up". Several days later, I did another update and upgrade, and the chromium packages were list...

Re: Facing heating problem

It sounds like you are concerned about how hot your Raspberry Pi ZERO is getting. First question: Is this just a concern, or are you actually having problems due to overheating?\ In either scenario, you can cool it by: increasing airflow over the Pi. Usually people have problems with temperature whe...

Re: Raspberry Pi is unusable as everyday computer

Whether or not a Raspberry Pi is sufficient for you depends on what you prioritize. I prioritize simplicity, changeability, responsiveness, and reliability. Some people prioritize "brute force" computers with more resources, but they are usually hands-off in comparison to Raspbian and have a very co...

Re: Audio works with HDMI, audio does not work with 3.5 mm jack

To clarify, I use dtparam=audio=off in CONJUNCTION with a USB sound card. If you don't have a USB sound card on hand, turn on the built-in audio chip on again. Try setting the ALSA default directly, instead of through the raspi-config tool. Steps to try: 1. enable the onboard audio chip in config.tx...

Re: Audio works with HDMI, audio does not work with 3.5 mm jack

This answer is based off of my experience with a Raspberry Pi 3 running Raspbian Stretch. As far as I understand, raspi-config just sets the ALSA default audio output. I've had some programs ignore the ALSA default, others refuse to play if the it is set to 3.5mm audio jack. In my quest for consiste...

Re: Moving from a 8GB micro SD card to a 32 GB micro SD card

You can copy to a larger SD Card using the SD Copier in Raspbian. "Removing" NOOBS is a bit more problematic. It is possible to move a Raspbian installation to a new SD Card, but not exactly straightforward, The easiest is to do a fresh installation of Raspbian (any flavour), then use `rsync` to co...

This question is based on my experience on a Raspberry Pi 3 running Raspbian. I cannot provide you any NOOBS-specific information, but I do know how to copy a filesystem from one device to another. Both these below solutions assume you are running your Pi 2 off the built-in card slot, and you have t...

Are you using the SSD as extra storage space, or is your Pi booting from it?

Re: What cable can I use to connect these 3 devices

The connectors on the cable ends internally connect together contact positions which are ground on the PC and drive. The corresponding positions on a RPi GPIO header are not ground and connecting them together causes electrical damage to the SoC which cannot be repaired. If unsure, count 10 ridges ...

Re: What cable can I use to connect these 3 devices

Yes both devices could be relying on the same pins, but I'm assuming gullbaek has already sucessfully tried them stacked. Witty pi has male headers on one side and female headers on the other side. Because of that, the cables will physically work. I'm not so sure about electrically work though... Gu...

Re: Using PWM to slow down a motor

You never want to power a motor directly from a GPIO pin, it won't work and you risk frying your Pi. PWM stands for P ulse W idth M odulation.

I am not aware of any arguments you can add to scratch2.
Scratch 2 simply opens the first filename it sees.

That's because Scratch 2 is trying to open a nonexistent file called "presentation".
