Everytime I encode my songs to lossy formats, the output file keeps the tags (title, artist, album, etc...), but drops the album art.

I tried to encode to any lossy format, including AAC, OGG and OPUS. They all drop the album art... except MP3.

I've figured out that I can't encode my songs to M4A and OGG formats, unless I add -vn flag, which removes the album art. So instead of M4A and OGG, i tried any other container, including .aac, .oga, .mka. But they all drop the album art too.

What I've tried:

ffmpeg -y -i "/storage/sdcard1/Music/01 Adam Foroush.m4a" -c:a libopus -b:a 128k -af aresample=48000:resampler=soxr:precision=33:cheby=1:dither_method=shibata -vbr on -compression_level 10 -frame_duration 60 -application audio "/storage/emulated/0/FFMPEG/01 Adam Foroush.opus"

Things gets more weird when I use opus-tools (to encode to OPUS) and used vorbis-tools (to encode to OGG). Unlike FFmpeg, they both gave me output files that retained the album art. But I don't like to use them since they both have poor input decoding support.

And about FFmpeg, I know I can encode my songs to OPUS, OGG or AAC, and then in the next step, embed the album art in them, but that's not a good solution.

Anyone? Any help?

I faced this problem too, the answer is very easy, just pass -c:v copy and that's all. FFMpeg tries to encode any video to h264 format by default, but audio containers not supporting this, so we should copy .jpg cover without encoding. And please, do not covert lossy format to other lossy, use lossless as source

FFmpeg version 4.4 automatically supports embedding album art into Ogg containers with the Theora video codec (see "Ogg codecs" on Wikipedia for a list of supported codecs, although they may not all be supported by FFmpeg).

Here's an example converting an MP3 file with a video track containing album art to an Ogg file with Opus encoded audio and Theora encoded video:
