The failure interface
To solve
The result check found that there were Chinese characters in the path name, which caused the problem of reading, so a new directory was created and the problem was solved.
At the same time, if there are possible escape characters in the imported video, it is necessary to double mark the slash.
In addition, sometimes there is a problem with thumbnail paths (using relative paths), so try importing absolute paths and running them again. Most of them can be solved according to the above three situations.
