-iOS has strict requirements for video files, requiring h264 or h265 video codec and aac audio codec in MP4 container. This can sometimes be a lower quality than the best quality available. To accommodate iOS requirements, when downloading a MP4 format you can choose "Best (iOS)" to get the best quality formats as compatible as possible with iOS requirements.

Any issues you might be experiencing with authentication to video websites, postprocessing, permissions, other `YTDL_OPTIONS` configurations which seem not to work, or anything else that concerns the workings of the underlying yt-dlp library, need not be opened on the MeTube project. In order to debug and troubleshoot them, it's advised to try using the yt-dlp binary directly first, bypassing the UI, and once that is working, importing the options that worked for you into `YTDL_OPTIONS`.

If your use cases are different and require additional features, please feel free to submit PRs that implement those features. It's advisable to create an issue first to discuss the planned implementation, because in an effort to reduce bloat, some PRs may not be accepted. However, note that opening a feature request when you don't intend to implement the feature will rarely result in the request being fulfilled.
