I have tried to get the highest possible audio bitrate from this YouTube video, in this case format 22 being 22 mp4 1280x720 720p 359k , avc1.64001F, mp4a.40.2@192k (44100Hz) (best) or 192k audio, and the resulting file is 128k. Same with format 251 on the same video, which is 251 webm audio only DASH audio 102k , webm_dash container, opus @160k (48000Hz) with the resulting file being much lower bitrate than 160k (different bitrates reported in different programs, ranging from 64k-99k, but never 160k). Can somebody please help me by telling me if I am doing something wrong? I recently redownloaded youtube-dl (weird update issue idk) from ytdl.org, so that couldn't be the problem.

Blame Youtube for providing wrong bitrate metadata.
