“Capture” for the next step, i.e. BuildRoot build for headless test.

wget https://file-examples.com/storage/fe3abb0cc967520c59b97f1/2018/04/file_example_AVI_640_800kB.avi
ffmpeg -stream_loop -1 -re -i file_example_AVI_640_800kB.avi -s 1280x720 -f v4l2 /dev/video0

Due to change for “/dev/video0” part (because capture device is a file descriptor eventually). Then I just need playback and comparison to get success/failure condition…

Video streamed with ffmpeg, and played with ffplay through with my WiP V4L2 loopback driver.

The next step is to detach the producer from /dev/videoX fops and instead return anonymous inode, which owns a file where the capture device can write the video stream.

The video resolution in this smoke test is 640x480, and the encoder scales it up in real-time to 1280x720.

@chimbosonic @teve Feels just tragic that we've spend billions and billions to build these fast connections between computers and we still have just 2024 versions of AOL or CompuServe. No one can talk to each other in bits.

@chimbosonic @teve ya... it is sad

I mean I did regularly in 1996 e.g. /dcc send ;-) good times...

Or like wouldn't it be cool if you could just plain call your mates computer? WA or similar not required all-in-the-client...

@teve IPv6 is not really for the masses or like especially providing end user apps requiring IPv6. So not like extremely huge surprise...

I heard that recently YLE turned it on so points up for that!

Time is an ocean in a storm...
35 years ago today, Prince of Persia was released on Apple II.

A huge, heartfelt THANK YOU to all who've shared this incredible journey.❤️🙏🕹️

Itsehän myös kirjoitin tästä samasta Hesarissa pari viikkoa sitten.

X:n muutos on kuitenkin ollut nähtävissä jo kahden vuoden ajan, mutta siltä on haluttu sulkea silmät. Miltä kaikelta olisi voitu välttyä, jos globaali viestintäyhteisö olisi silloin jo tehnyt oikeat johtopäätökset?

I like in Rust how it returns back to MS-DOS on in executables and libraries ;-)

No joke. Makes debugging so much better experience...

DSO's suck... (for most part unless they are actually needed).

The only person I've talk to and with whom I can share my IPv6 grit has been David Woodhouse. He really gets this! I wish more PE's in big companies were like David (he works at AWS).

If you are PE of your company who has influence, be "the dwmw2" of your corps ;-)

Make a difference. In tech.

@travisfw To install full collection of currently popular linkers in Fedora:

sudo dnf install binutils-gold mold lld

This excludes wild, which needs to be installed through cargo:

cargo install --locked --bin wild --git https://github.com/davidlattimore/wild.git wild

Think how much some IM services could scale down in service if computers could actually talk to each other.

Fuck NAT.

IPv4 Internet of today

I wonder whether 2025 will be the year of IPv6.

I miss 90s and dialup as then you could actually speak to another computer no strings attached...

In some ways Internet was more advanced in tech back then ;-)

@travisfw then you should read this some day :-) it's still relevant and best book on topic. and as weird as it sounds it is nicely written, has nice backstories and generally very nice story telling.

Learned something pretty basic but also somewhat essential in software and systems engineering, i.e. how to switch the default linker in #Fedora :-)

PS. Needs sudo in order to make an effective change.

They’ve got a lot more work to do, but I like this. https://blog.mozilla.org/en/mozilla/mozilla-brand-next-era-of-tech/

It's slow refactoring because it is too easy to judge something "messy" and destroy "gray knowledge" while doing it ;-)
