#4286 new defect
Still image should be muxed as picture attachment
|Reported by:||Nietzsche||Owned by:|
|Blocking:||Reproduced by developer:||no|
|Analyzed by developer:||no|
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)

|Priority:||normal → wish|
|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.)
