<p>oh yes, every commit is fully open about Claude Code + the model.<p>honestly, it would've taken me about 2 years to do this otherwise.<p>there are many FATE tests added and a lot more to add when the hardware verification bits i'm planning are done.<p>edit: do you know if upstream have ever taken an AI assisted commit? i've not seen anything yet and would hate to be controversial or a burden on hardworking reviewers!</p>

<p>FFmpeg converts everything except subtitles across format boundaries. SRT to Blu-ray PGS? "Subtitle encoding currently only possible from text to text or bitmap to bitmap." Ticket #3819, filed 2014.<p>I built this with Claude Code over a few weeks. Claude wrote most of the encoder, found an integer overflow in the decoder buffer tracking, and ran review from five angles. I read the Panasonic and Sony patents, made the architectural calls, and told it when it was wrong about the spec. We argued about whether DTS computation belongs in the muxer. (It does, and also in fftools. We did both.)<p>Animation is an interesting problem. Advanced SubStation Alpha fades have to survive conversion to Blu-ray's PGS format. The encoder watches pixel changes between frames and classifies them: palette shift or full redraw. Fades become palette-only updates, no bitmap retransmission. Overlapping subtitles with different end times took four rewrites and an event lookahead window.<p>I'd like to maintain this properly and get the patches upstream eventually. If you hit a bug or have a subtitle workflow that doesn't work, open an issue. I'm dead curious what people do with this, but i have some plans for translation related plugins building on the OCR work.<p>Six iterations. 23 patches. libass and Tesseract were already in FFmpeg's filter library. I wired them into the main pipeline the same way sub2video works. Text to bitmap, bitmap to text, 114 OCR languages, RGBA-to-GIF. The development page has the history.<p>Pre-built for 6 platforms, no dependencies: <a href="https://connollydavid.github.io/pgs-release/" rel="nofollow">https://connollydavid.github.io/pgs-release/</a></p>

<p>This works really well in Ireland. Eircodes (our late adoption postal codes) resolve to individual addresses rather than areas, so Irish sites mostly do this.</p>

<p>also, was it some formal declaration by this body, or just someone with an email address from the organization?<p>doubtless, the irish representatives wouldn't support any divergence between Dublin and Belfast, (especially considering this is wrong from a spatial perspective as population density is heavily skewed to the east of the island).<p>edit: i was curious enough to email all of the irish delegates to this organisation. some fairly heavy hitters, as a citizen with a keen interest in Dublin & Belfast being in the same timezone will be interesting to hear back!</p>
