* `prefer_multi_flv`: Prefer extracting flv formats over mp4 for older videos that still provide legacy formats
|
||||
|
||||
#### digitalconcerthall
|
||||
* `prefer_combined_hls`: Prefer extracting combined/pre-merged video and audio HLS formats. This will exclude 4K/HEVC video and lossless/FLAC audio formats, which are only available as split video/audio HLS formats

**Note**: These options may be changed/removed in the future without concern for backward compatibility
