When I download a song with youtube-dl into AAC, then I cannot import it into iTunes. iTunes doesn't give an error. It just ignores it.
youtube-dl -x --audio-format aac https://www.youtube.com/watch?v=abc123 --verbose [download] 100% of 5.88MiB in 00:03 [debug] ffmpeg command line: ffprobe -show_streams "file:xxxxxx.webm" [ffmpeg] Destination: xxxxxxxx-xxxxxxxxx.aac [debug] ffmpeg command line: ffmpeg -y -loglevel "repeat+info" -i "file:xxxxxxxxxxxx.webm" -vn -acodec aac "-q:a" 5 -f adts "file:xxxxxxxx.aac" Deleting original file xxxxxxxxxxxx.webm (pass -k to keep)
ffprobe xxxxxxxxxxxx.aac [aac @ 0000006501ace3c0] Estimating duration from bitrate, this may be inaccurate Input #0, aac, from 'xxxxxxxxx.aac': Duration: 00:12:39.84, bitrate: 249 kb/s Stream #0:0: Audio: aac (LC), 48000 Hz, stereo, fltp, 249 kb/s
It works with m4a.
iTunes Version 184.108.40.206
@nohillside Yes it happens with all AAC files I try to download with youtuble-dl. Yes it does work if I use mp3 also. Yes I am using Windows.
@slm I don't have any original AAC files to test with. All AAC files have been generated with ffmpeg/youtube-dl. I found this sample AAC file from http://samplephotovideo.com/2015/12/download-aac-mpeg-2-advanced-audio-coding-file/, http://cdn.online-convert.com/example-file/audio/example.aac, and was unable to import it into iTunes. Drag & Drop shows a red-circle-crossed and File > Add File to Library just ignores it.
