Tdarr_Plugins VS Downmixer

there is also a pull request with this @ https://github.com/HaveAGitGat/Tdarr_Plugins to include it there.

u/dewitpj you can use multiple GPUs with this plugin: https://github.com/HaveAGitGat/Tdarr_Plugins/pull/341/files

It works really well if you give it example file info (such as https://docs.tdarr.io/docs/plugins/plugin-components/parameters/file) and then give it an example plugin (such as https://github.com/HaveAGitGat/Tdarr_Plugins/blob/master/examples/Tdarr_Plugin_pre1_Pre_Proc_Example.js)

Then all you need to do is have your plugin determin the handbrake profile based on the files resolution, which is easy to do, I've mentioned how to do this within your own plugin using an example from the DOOM Tiered plugin.

The other would be to add the Tdarr_Plugin_00td_filter_by_resolution plugin to the start of your stack and include/exclude the resolutions you want to process or don't want to process.

What you're looking for is a plugin that determins the output settings based on the audio channels or files resolution, the DOOM Tierd plugin is a good example of this as it adjusts the video bitrate based on the resolution.

First step is to Fork the original repository, Click Fork it will be in the top right, you should then be redirected to your forked version of Tdarr_Plugins

BTW, I happen to have code for downmixing that works by appending an audio stream and setting it to first position. I wrote this to use for a single set of files that I ripped from DVD, so I knew exactly what I was working with, but the relevant ffmpeg part should be useuful:
