Re: FFmpeg "Illegal instruction" Raspberry Pi Zero W

Why do you use sudo ? when FFmpeg tries to re-write on the same output file it needs permission use -y instead ffmpeg -y -ss 00:00:10 -t 00:00:30 -i "/home/pi/Desktop/jpFiles/GOPR2546.MP4" "/home/pi/Desktop/jpFiles/JoyPro2.mp4" 1) Are you using a proper power supply or are you using a phone charger...

Re: FFmpeg "Illegal instruction" Raspberry Pi Zero W

what do you think I'm missing here? Why do you use sudo ? There are a few possible causes: 1) Are you using a proper power supply or are you using a phone charger ? 2) Is the Pi 0W in a case ? (temperature!) 3) Are you using a quality memory card ? You must be aware that (this) ffmpeg is a heavy jo...

Re: FFmpeg "Illegal instruction" Raspberry Pi Zero W

so your recommendation would be to install the Raspbian Buster with desktop version and using the already FFmpeg version in that image and test it from there? Yes, but reduce the GPU memory to 16MB and increase the swap file size in /etc/dphys-swapfile. Alternatively using Buster Lite you could ins...

Re: Booting from USB on RPi3

Yes. You should change the title of your post because your problem is that booting from an SD card in a USB card reader fails. My experience is that this is as expected because a card reader is not the same as an USB storage device. Not true. I just double-checked and it boots here in a Raspberry P...

Would it be possible to drill the fixation holes 0,05mm bigger, so that standard 3mm screws could be used?
Currently I must enlarge every hole to fix the PCB with regular DIN screws.
:(
M2.5 is a regular ISO/DIN metric screw thread.

Add a new bridge, which in this case is called "br0". ... Connect the network ports. In this case, connect "eth0" to the bridge "br0". Does systemd requires the device to be alive at config time? If not, this runtime dance with brctl is completely superfluous. And I don't think systemd-networking r...

Very likely your SD card has gone into read only mode, time to replace the card.
