🌀 Disordered order

when your video more than 10，the order will error，like：

BTW，Can you add an output format option? For example, when merging webm videos, the default output is webm format, but sometimes I want the output format to be mp4, and then I can use - o mp4 to specify the output format.

Heyy Senlin! 👋

What so you mean with error? If you name them like 01, 02, ... it should be fine 😊

The output file extension is always the same as the inputs, it's kinda hard to change that 😬
