*no longer lights up the photo. Of course it lights up the area, just too early.

Android turned the screenshot around again. 🙃 Just do a handstand to read it.

Hm, seems not easily possible. If I just pipe it directly into VLC, I get no audio. If I download it to a file, I can immediately start that, but there is some unknown delay until the file is actually created, so I have to wait for that until starting VLC, which is annoying to script. So, about your answer: Do you mean there is some technological limitation why Privoxy cannot block YouTube/Twitch ads or do you mean that it's just not implemented yet? Is there something else that can block it, maybe...
Ad blockers as browser extensions can successfully block Twitch ads, but I guess that works differently. Your youtube-dl suggestion gave me an idea: I'm already using yt-dlp to get the playlist URL to insert into VLC, but maybe I can run it in actual download mode and output that to StdOut or somehow else pump it into VLC, so I would not actually use VLC for the internet connection, but yt-dlp. I'll see what I can do there.

I was pointed to this report by the Eclipse support. All Eclipse installer archives since 2018-10 are affected by this problem.
