24 alternatives to I fixed FFmpeg's subtitle conversion (the bug from 2014)
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. 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.)…
This is an FFmpeg extension that converts subtitles across different format boundaries, resolving a limitation that existed since 2014.

I found that I am using ChatGPT more and more to get the FFmpeg command I need, but the process can be a bit tedious: copy-pasting commands, dealing with input file names and locations, making sure the prompt contains enough info about the input files. This site attempts to solve that. You just describe what you want to do, pick the input files and an LLM (currently DeepSeek) generates the FFmpeg command. You can then run it directly in your browser or use the command elsewhere.
