douyin-downloader

Parse the share link with parse_douyin.py to get the download_url, which is the play address with playwm replaced by play, then pass it to download_video.py with an output path. The result is a watermark-free MP4 file.

Run transcribe_audio.py on the downloaded video file with your Volcano Engine App Key and Access Key, either as arguments or via the VOLC_APP_KEY and VOLC_ACCESS_KEY environment variables. It returns the recognized text as JSON and can write a plain text file.

The scripts require Python 3 and the requests library, installed with pip3 install requests. The transcription script uses only the Python standard library but needs valid Volcano Engine ASR credentials.

Parsing fails when the input contains no valid URL, the share link is unreachable, or the page structure changed so window._ROUTER_DATA cannot be found. Retry the request or update the script if Douyin modified its share page HTML.

The transcription script rejects files larger than 100MB and requires valid App Key and Access Key credentials from the Volcano Engine console. Standard mode polls for results with a default timeout of 120 seconds.
