Synthetic missing-audio example / 合成缺音軌示範

Check stored video dimensions, duration, codec and audio-stream presence against your delivery requirements. US$9 one-time Python download; PyAV required, no model key or GUI.

依交付規格核對影片儲存寬高、時長、編碼與音軌是否存在。US$9買斷Python包，需PyAV，不需模型金鑰，沒有圖形介面。

Three steps

三步開始

  1. Extract the package and install requirements.txt in your Python environment.

  2. Generate the synthetic video and run the command below.

  3. Read status and issues in the JSON output; replace the input path and specifications to check your own trusted local video.

  4. 解壓，在自己的Python環境安裝requirements.txt。

  5. 產生合成影片並執行下方指令。

  6. JSON直接列出檢查結果與問題；換入自己的可信本機影片及交付規格即可使用。

python3 -m pip install -r requirements.txt
python3 scripts/demo.py demo.mp4
python3 scripts/check.py --input demo.mp4 --width 320 --height 240 --max-seconds 2 --audio required

Actual result

實際結果

The synthetic 320x240, one-second video has no audio: AUDIO_STREAM_MISSING, exit 1. Set --audio absent to require no audio; use --min-seconds and --max-seconds to bound duration and --codec for an optional codec match.

合成影片為320×240、一秒、無音軌，會得到AUDIO_STREAM_MISSING與退出碼1。--audio absent要求沒有音軌；--min-seconds與--max-seconds指定時長，--codec可加上編碼條件。

Exit 0 means the selected metadata matches; 1 means issues found; 2 means input/dependency error. Input limit: regular local file up to 2 GB, no URL or symlink.

退出碼0代表指定規格一致，1代表發現問題，2代表輸入或依賴錯誤。接受2GB內的本機一般檔案，不接受網址或符號連結。

Scope and delivery

範圍與交付

Metadata only. An audio stream does not prove audible sound. No subtitle/OCR, content quality, full decoding integrity, rotated display-size or platform-acceptance validation.

只檢查中繼資料，有音軌不代表聲音可聽。不檢查字幕OCR、內容品質、完整解碼、旋轉後顯示尺寸，也不保證平台接受。

Python 3.10+ recommended; tested on macOS Python 3.9.6 with PyAV. Windows: use py -3 instead of python3. Windows/Linux clean installations unverified. Includes source, Skill guide and synthetic demo, package 0.1.0 Beta.

建議Python 3.10以上，已測macOS Python 3.9.6與PyAV；Windows以py -3取代python3，Windows/Linux尚未實測乾淨安裝。含原碼、Skill指引、合成範例，套件0.1.0 Beta。

US$9 one-time; no subscription, seller API or hosted service. Optional AI-client fees are yours. Support: [email protected] for installation and reproducible bugs; no custom integration or fixed response time.

US$9買斷，無月費、賣方API或託管服務，選用AI客戶端費用自付。支援[email protected]，提供安裝與可重現錯誤協助，不含客製整合或固定回覆時限。
