📝 Parameter Rules:
- Parameters are separated by underscores (
_) - If multiple parameters specify the same setting, the last one wins
- Unknown/invalid parameters are silently ignored
- Example:
/720p_h264_30fps_h265_60fps→ uses h265 codec and 60fps

⚠️ Important Notes:
- Most popular codecs and resolutions are pregenerated
- Unconventional params transcodes on demand and stays in cache
- First-time transcoding may take time depending on complexity
- AV1 encoding is slower but produces smaller files
- License incompatibilities: Some codec/container combinations may fail due to FFmpeg licensing restrictions (e.g., H.264 with WebM). Errors are returned directly from FFmpeg.
