Re: FFMPEG not working for me in PI4/Buster (compared to AVCONV Pi3)

Now after some more fiddling (removing quotes from input file specification, and removing -pattern_type glob), it runs correctly with a %d format specifier and even if input files are not zero-padded, still gets them in the correct order. I coulda SWORN I tried that yesterday. pi@RPI4:~/wxdata/a/t $...

Re: FFMPEG not working for me in PI4/Buster (compared to AVCONV Pi3)

Why doesn't my ffmpeg take "whatever%d.jpg" as the input? It always says no input file found. If I use "whatever*.jpg" it runs, but the numbers better be leading-zero padded or it takes them out of sequence. So why, when I input this command line, -rw-r--r-- 1 pi pi 118068 Aug 7 21:50 bala0.jpg -rw-...

Re: FFMPEG not working for me in PI4/Buster (compared to AVCONV Pi3)

Using image%d should always take sequential frames. image*.jpg will leave it open to how the shell expands the wildcard. Well i guess I shoulda known that was the problem...the shell is expanding the wildcards into a different lexicographic ordering on Buster. But why oh why does "input%d.jpg" not ...

Re: FFMPEG not working for me in PI4/Buster (compared to AVCONV Pi3)

I ran your posted script and it resulted in image1.jpg ... image360.jpg. Next I ran my ffmpeg line as follows: ffmpeg -r 10 -pattern_type glob -i 'image*.jpg' -c:v libx264 -pix_fmt yuv420p image__.mp4 It took about 2 minutes and produced image__.mp4 which jumps around because ffmpeg took the input f...

FFMPEG not working for me in PI4/Buster (compared to AVCONV Pi3)

Pi 4: Can we **please** have an rtc included?

Currently, installing any rtc on the Pi, even the 3B+, and getting the software right is "a dog's breakfast". There are so many articles about how to do it, files to edit, and I've not found a single one which entirely documents the process on 3B+ / stretch lite. I'm certain this would be solved by ...

Re: Raspbian Jessie Lite - missing bits!

. . . Python 2 vs python 3 is a such a mess it makes the language look even more stupid, how they can make a new version that's incompatible with the old version is beyond belief.

Re: USB boot, PI3B+: followed instructions, doesn't work

You don't need to set the OTP bit on the 3B+, it's set in the factory as standard. If I used Windows, I'd use Etcher to write the image file to the USB stick, as it is easier to use than the old Win32 Disk Imager program. Not all USB devices are compatible with the USB boot on the Pi, but I have fo...
