Flexibility and specialized features of the YAML configuration system
TubeTube uses YAML as the configuration language , through the structured settings.yaml file to achieve fine-grained media format control . The configuration file is divided into General/Music/Podcast/Video blocks by content type, and each block can independently set the audio encoding format (e.g., mp3/m4a), video encapsulation format (e.g., mp4/mkv), and the internal format ID of YouTube, which is designed to meet the codec requirements of professional users in different scenarios.
In terms of technical details, audio format ID '140' corresponds to YouTube's 128kbps AAC audio stream, and video format ID '625' represents 1080p H.264 encoding. Advanced users can combine specialized formats such as opus audio + VP9 video. The configuration engine listens for file changes in real time while the system is running, and new parameters can be applied without restarting the service.
Test data shows that compared with the graphical interface configuration tool, the YAML solution improves the efficiency of format switching by 5 times and supports version control system management. Typical application scenarios include: podcast production requires uniform m4a format, music library requires MP3 tags, 4K video retains the original encoding, and so on. In case of configuration error, the system will fall back to the last valid state to ensure service continuity.
