怀疑 执行last, awsmf_name = copyscript(script, folder + '.scripts/extract.vpy')出现错误

[henry-tujia]

初始化 last变量后，可以正确运行，但是报出

Script evaluation failed:
Python exception: invalid syntax (extract.vpy, line 33)

Traceback (most recent call last):
  File "src/cython/vapoursynth.pyx", line 2241, in vapoursynth.vpy_evaluateScript

(1/6) Processing encode with --crf 17

Traceback (most recent call last):
  File "vstest.py", line 332, in <module>
    encode(test + ' ' + ' '.join(codec_opts_passed) + ' ' + vbv_opts + ' ' + info)
TypeError: can only concatenate str (not "_wrap_close") to str

报错原因为 encode.ipynb 中缺少 src.set_output(),添加后报出以下：

Script evaluation failed:

这是第一次运行该脚本吗，之前是否 demux 失败过 建议完全删除相关文件和目录后再次重试
