4. Douyin Open Platform, uploading a video to the file server, file size: 117 MB. Response: 200. Upload successful. Time elapsed: 1 m 7.02 s. See Figure 3.
5. Note from the official documentation: For videos larger than 50M, chunked upload is recommended to reduce failures caused by gateway timeouts. For videos larger than 128M, chunked upload is required. The total video size must be within 4GB. The recommended size for a single chunk is 20MB, with a minimum of 5MB. The subsequent implementation logic for uploading videos: Regardless of size, all videos will be uploaded in chunks, with a single chunk size of 100 MB.
