bitfire is a tool that converts a resolution (like 480p) to a bitrate (like 300) and offers a switch between Mbps and Kbps.
To install, run
shell
% cargo install bitfire
With configuration, you can store a custom table as well you preference for using kbps with a config file. By default, bitfire will search ~/.config/bitfire/config.json for config. However, you can change this by changing the $BITFIRE_CONFIG environment variable or by passing in -c <PATH> or --config-path <PATH>. The json file recognizes 2 fields: "table" (a 'dictionary' or 'hashmap' consisting of strings and floats) as well as "use_kbps_by_default" (a boolean). The default configuration looks like this:
json
{
"table": {
"1080p": 3.000,
"720p": 1.500,
"540p": 0.989,
"360p": 0.460,
"270p": 0.327,
"180p": 0.193
},
"use_kbps_by_default": false
}
