Hello @futianhang! 👋 I'm Dosu, your friendly bot here to help with bugs, answer questions, and assist you in becoming a contributor while we wait for a human maintainer. Let's tackle this together! 😄

The issue you're experiencing with the dynamic cover download, where it downloads the first frame of the original cover instead, might be related to how the dynamic cover URL is being extracted or processed. In the TikTokDownloader codebase, the __extract_cover and __extract_cover_tiktok methods are responsible for extracting the dynamic cover URL from the data. These methods ensure that the dynamic cover URL is correctly assigned to item["dynamic_cover"], which is then used in the download_cover method ^[1][2].

If the dynamic cover is not downloading as expected, you might want to check if the URL being extracted is correct and if the conditions in the download_cover method are being met. Additionally, ensure that there are no known issues affecting this feature, such as the one documented in version 5.3, where cover images and GIFs were being re-downloaded regardless of existing files ^[3].

If the problem persists, reviewing the extraction logic or updating to the latest version of the tool might help resolve the issue.
