Missing VP9 thumbnails Hannibal Chew 2018/02/12 (Mon) 21:07:51 No.1794

It looks like vp9 webms don't have thumbnails: >>>/cult/1673 & >>>/cult/1656

I think this is where thumbnails for webms are generated:
https://github.com/arisu-dev/arisuchan/blob/master/inc/lib/webm/ffmpeg.php#L43

Since it uses ffmpeg and the command seems to be correct, simply updating ffmpeg will probably fix it.

Or maybe it's Firefox that can't play the thumbnail? It seems to be there and mpv can play it without any problems:

On Chromium and thumbnails also don't show

I'm testing it out now.

I was wrong, after reading https://github.com/arisu-dev/arisuchan/blob/master/inc/lib/webm/posthandler.php it seems that the problem is that Arisuchan does not use ffmpeg but some hand-written PHP webm parser, maybe we could try setting

$config['webm']['use_ffmpeg']

to true and test if that fixes the problem.

I've made that change and rebuilt the board.

Can you set

$config['webm']['allow_audio']

to true? For some reason the previous setting ignored it but now you can't post webm with audio.
