Youtube download customisation

[simb24]

In many attempts I didn't find way to download from Youtube only H264+AAC mp4 formats video. How I can modify config.yml or any other way to achieving that? I use Synology NAS docker. Any options apart best, such as MP4, created video without audio. Thanks in advance.

@simb24 Check out youtube-dl's documentation. In your config.yml file you can try adding the following to the ydl_options: section

• This example is directly from youtube-dl's readme. It'll attempt to grab the highest quality mp4 video & m4a (aac) audio as separate streams first, otherwise the best quality mp4 file (based on a muxed stream), or otherwise the best possible stream.

  format: 'bestvideo[ext=mp4]+bestaudio[ext=m4a]/best[ext=mp4]/best'

EDIT: However, this assumes that the format key takes precedence over the webui configuration. I'm still skimming over the project, so I can't be certain. If I find time, I'll spin up a new container and test it out myself. @simb24, In the meantime, this info is still useful if you're comfortable with the command line and really need a specific output format.

I'm sure you can find more on the /r/youtubedl subreddit. I figured it out myself by trying out the stuff from the readme. If you get youtube-dl onto your computer, you can play around with the --list-formats/-F option to list available formats for a particular URL. For example, this is the output from running youtube-dl -F https://www.youtube.com/watch?v=RxzC2S8Z2Ng

Thank you, unfortunately doesn't changed anything, by choosing "best" the video is same as was before, as well as do not affected to any other options chosen. By choosing "MP4" the video is only 720p. My targets is to be able choosing 1080 or less, AAC audio and h264 codec. A1 video and opus audio doesn't supported by my existed players. Any idea how I can achieve it?
