--acodec ACODEC                             Audio codec for ffmpeg transcoding.

--ffmpeg-options FFMPEG_OPTIONS             Additional ffmpeg options. (e.g. --ffmpeg-options "-acodec copy -vcodec copy")

--thread THREAD                             Number of threads for downloading. Defaults to 1. (NOT RECOMMENDED TO EDIT)

DO NOT SHARE THE TOKEN WITH ANYONE.**


Sometimes this tool may not function properly, delete temp files and folder to make it re-download the video.


(Feel free to modify the .json file if you understand what you are doing.)

## --select-manually

When downloading the whole channel, you can use this option to manually select the videos to be downloaded.

- `Arrow Up`/`Arrow Down`, `Arrow Left`/`Arrow Right`: Navigate

- `Space`: Select / Deselect

- `Enter`: Start download

- `Ctrl + A`: Select all

- `Ctrl + R`: Deselct all

- `Ctrl + W`: Use filter

The filter supports either with noarmal keyword-filtering or lambda expression (**Case-Sensitive**). 


Videos will be selected if they match the conditions.

- `/only `: Select videos that contain the keyword only.

- `/add `: Add the videos that contain the keyword to selection.

- `/remove `: Remove the videos that contains the keyword from selection.

- `/lambda `: Use lambda expression to filter the videos.

The syntax of the lambda expression does not need to include the `lambda x:` part, and should return a boolean value. 


The following is an example of a lambda expression that selects the video with 

- title containing "ASMR"; 

- length of title is greater than 30; 

- index is greater than 10; 

- and the content code contains letter "R".

`/lambda "ASMR" in x.title and len(x.title) > 30 and x.index > 10 and "R" in x.content_code`

The x object has the following attributes:

- `title`: Title of the video.

- `index`: Index of the video.

- `content_code`: Content code of the video.

**NOTE: lambda expression is case-sensitive. You can use `.lower()` to make it all lowercase.**


**Python built-in functions and variables are supported in the lambda expression.**
