Not to commenting on the youtube-dl but trying to answer your Opus audio related questions.Īs ffcvt suggested, " the Opus audio codec is becoming the best thing ever for compressing audio - A 64K Opu audio stream is comparable to mp3 files of 128K to 256K bandwidth". So, my question is: Do you think I should download the AAC track instead of the Opus track, or should I just let youtube-dl does its stuff? What benefit will I get downloading the Opus track compared to downloading the AAC track? (FI, I have no problem playing the remuxed video+audio using MPC-HC + K-Lite Mega Codecs, and I also have no problem extracting the audio using ffmpeg -c:a copy and playing it using Foobar2000) Which means the Opus audio track will be a lossy-transcode from AAC, potentially reducing quality. However, I also know that Opus audio is not supported by the MP4 container, and since uploads to YouTube does not (yet) support MKV, the original upload would be using AAC. I know that, encoded from source, Opus tracks usually have better quality than AAC tracks at the same bitrate. I noted that left to its defaults, youtube-dl will use bestvideo+bestaudio, and with recent videos, for bestaudio it will nearly invariably download the Opus track. I have been using youtube-dl to download some music videos from YouTube. No, this is not a duplicate of this question.
