The honest answer: because it shouldn’t work and has never been done before. TeX has no arrays, no functions with return values, no convenient local variables or stack frames, no integers bigger than 2^{31}-1, no bitwise operations. Macro expansion can recurse, but you get no call stack and deep recursion quickly hits engine limits. What TeX does have is a Turing-complete macro expansion engine and, with e-TeX extensions (used by modern pdfTeX), up to 32,768 integer registers called \count. That turns out to be just barely enough to implement a chess engine.。关于这个话题，新收录的资料提供了深入分析

With more efficient multi-lane encoding and real-time quality metrics, we were able to fully deprecate our internal FFmpeg fork for all VOD and livestreaming pipelines. And thanks to standardized hardware APIs in FFmpeg, we’ve been able to support our MSVP ASIC alongside software-based pipelines with minimal friction.，详情可参考新收录的资料
