🚀 The feature

Use one streamwriter to write multiple videos.

Motivation, pitch

Can the streamwriter support writing multiple videos using the same object, with each video corresponding to a different stream when I use gpu to encode? In current situation, this result in writing to the same buffer, ultimately producing one video. How can I do this? This can avoid the overhead caused by multiple initializations and destructions of the streamwriter.
