WYSIWYG cross-platform multi-lingual music composition and notation The correct command is: ffmpeg -i "without_cover.mkv" -attach "art_cover.jpg" -map 0 -c copy -metadata:s:t mimetype="image/jpeg" -metadata:s:t:0 filename="cover.jpeg" "with_cover.- MuseScore 4 sheet music editor SYNOPSIS mscore As in the command I posted this, the field was with jpg, the codec, despite not giving an error, simply attached the image without any encoding, causing many problems at the time of conversion. Note that where is jpg, it has to be jpeg. What happens is that the mjpeg codec, looks for information in the command so that it can encode the image correctly, this information is in the mimetype="image/ jpg" field. I used the second command that I posted here in some mkv files I have and, although they are attached without an error message, when I went to convert the files with the cover art into mp3, the system showed a codec error in the image and only converted the audio to mp3. Note about the second command posted at top: Note: q:a 9 is equivalent to 320 kbps VBR.Įquivalences when encoding with libvorbis to MKV format: -q:a 4 ~= 128 kbps VBR If you wanted to change the audio in MKV format use -c:a libvorbis -q:a 9 ,VBR format, or c:a libvorbis -b:a 320, CBR format, but the file will be re-encoded. The audio on the output remains with the same settings as the input. In the output file, streams #0:0, #0:1 were kept and stream #0:2 was included, which is the cover art stream. Output of ffprobe output_sample.mkv: Stream #0:0: Audio: mp3, 44100 Hz, stereo, fltp, 320 kb/s Output of ffprobe input_sample.mp3: Stream #0:0: Audio: mp3, 44100 Hz, stereo, fltp, 320 kb/s If you would like to attach an image that is not embedded in the mp3 file then this is a way to do that: ffmpeg -i "input_sample.mp3" -attach "image_cover.jpg" -map 0 -c:v copy -metadata:s:t mimetype="image/jpg" -metadata:s:t:0 filename="cover.jpg" "output_sample.mkv" See more details at this Stack Overflow thread at: How to add album art with ffmpeg? ffmpeg -i "input.mp3" -map 0:0 -map 0:1 -c copy -id3v2_version 3 -metadata:s:v title="Album cover" -metadata:s:v comment="Cover (front)" "output.mkv" In this case, the audio remains in the output file with the same settings as the input mp3. To include embedded cover art when converting an mp3 to mkv file, I use below command.
