支持TRANSCRIPT CLAIM
当命令已经变成一份完整计划,“专业系统最后都会换成 API”就不再是必然结论。 二零二六年五月,Lex Fridman 发布了一场关于 FFmpeg 的长篇访谈。两位嘉宾 Jean-Baptiste Kempf 和 Kieran Kunhya 都长期参与 FFmpeg 及其周边工作。访谈在这里谈到两种确实并存的专业路径:有些公司使用 API,有些公司生成很长的 command line。 Jean-Baptiste Kempf(原声): It's a language. It's an actual language. Lex Fridman(原声): It's an actual, yeah, you could think of it as a programming language. Jean-Baptiste Kempf(原声): Yeah, of course, I'm sure. Because, so most of the people, they're going to take FFmpeg, file in, file out, and specify the format, right? But you can, we've seen thousands of characters, and we've seen also, like, people doing programming, generation of command lines to make FFmpeg.
