2024-04-16 (projectcontour + GKE)

Https://Add.dog went down. To Fix:

  1. Updated GKE control plane
  2. Copied https://github.com/projectcontour/contour/tree/main/examples/contour into my_kubernetes
  3. Applied with kubectl
  4. Strange, stern contour -n project contour still showed an annotation error. But site works now.

Scan LAN for connected devices : sudo arp-scan --localnet

Starting to think that BUSTER is the right raspiOS for these 2015-2017 Raspberry pis.

Something is terribly wrong with COMPOSITE out on all my Raspberry Pi 3s

Happy PI Zero 😀 BUSTER

VLC media player 3.0.17.4 Vetinari (revision 3.0.13-8-g41878ff4f2) is a working version ✅

Could VLC media player 3.0.20 Vetinari (revision 3.0.20-0-g6f0d0ab126b) be bad for Buster on RPi Zero?

Open question remains

  1. Verify there is indeed something wrong with VLC media player 3.0.20 Vetinari (revision 3.0.20-0-g6f0d0ab126b) on Zero Buster
  2. How to install 3.0.17.4 Vetinari (revision 3.0.13-8-g41878ff4f2 specifically. vlc=3.0.17.4-0+deb10u2+rpt1 didn’t work. From source?

https://wiki.videolan.org/VLC_command-line_help/

Solution: /boot/firmware/config.txt is used vs /book/config/config.txt

These don’t seem needed

export DISPLAY=:0
cvlc --x11-display :0

This command works on Bookworm

cvlc --no-audio -L -R --no-video-title-show --crop=4:3 "$(yt-dlp -g -f 18 https://www.youtube.com/watch?v=zg_fAUsNVJ4)"

Useful working config


[all]

sdtv_mode=0
sdtv_aspect=1
hdmi_ignore_hotplug=1
dtoverlay=vc4-kms-v3d,composite
enable_tvout=1


# adjust resolution

Doing some Youtube archiving with this tool. Turns out ONLY CHROME works with the redirect.

I’m using the hack-repo to manage the metaJSON files when uploading concat’d archive footage from camera : ffmpeg -f concat -safe 0 -I list.txt -c:v copy -c:a copy -y <filename>

// list.txt
file 00000.MTS
file 00001.MTS
file 00002.MTS

Then the upload command youtubeuploader -filename my_video.mts -secrets ../youtube-upload/client_secrets.json --privacy unlisted Must copy the browser URL into Chrome!

Of course all the setup instructions on the youtubeuploader project must be followed!

This is all going to stephletteandsamlette

Could AI power a headless browser? Could a prompt become automated browser commands?

Idea would be to use AI agent to explore a website looking for items-of-interest, saving the consumer the need to check a website, & save the programmer coding the automated paths that will become outdated when the website gets a redesign.

youtube closed captions -> SRT with AI.

Rare Olivier Messiaen - The Crystal Liturgy found on Archive.org has no subtitles to share with non French speakers.

I uploaded this to youtube private to generate closed captions. Copied the file from the Network monitor, but its in a youtue format. This needs to be converted, but no converter exists. AI to rescue.

Canceled OpenAI in favor of Claude after it did a crazy cool job converting a youtube closed caption file into an SRT.

No official way exists to do this.

Chat GPT v4 stumbled through this, but after 3 prompts to fix the SRT from:

Claude succeeded in making a valid SRT that i added with ffmpeg -i input_video.mp4 -i captions.srt -c:v copy -c:a copy -c:s mov_text -metadata:s:s:0 language=eng output_video.mp4

Files: youtube closed caption file shortened after inspecting Network tab
