Description

Hi,

I created a webm made of a sound file and a still image with this command:

ffmpeg -i folder.jpg -report -i "23 - Ripe Seeds (Plant Castle BGM).flac" -threads 8 -c:v libvpx -crf 10 -qmin 5 -qmax 55 -vf "scale=360:-1" -c:a libvorbis -ac 2 -b:a 128K out.webm

Seeking is unsupported (according to the mpv dev, the index is broken and contain only one entry: the beginning of the video, ​https://github.com/mpv-player/mpv/issues/1533)

Summary: Still image video contain a bad index → Still image should be muxed as picture attachment

FFmpeg actually creates a valid file. Some players (like mpv) will have trouble seeking in it, because it has only 1 video frame, but a large audio track.

What FFmpeg should do is not creating obscure files, but making the picture an attachment.

(In case of confusion, I'm wm4.)
