That's nuts. You can turn png into webm. Similarly you can turn mp3 to webm. Are you serious?

webm is a container
vp8/vp9 video codec
vorbis/opus audio codec
g damn it g

104mb mp3

what the fuck is that a 5 hour movie?

Why does it have to be bigger than 4 millibits?

This thread is a shame.
What has Jow Forums become?
It's so sad.

104 mb is already >4 mb
My, God, /gee/ these days...

>tfw Hatsune Miku Remembers 10,000 digits of Pi is only available in 128k MP3 for 62MB.

Jow Forums has a limit on how long the webm can be anyway, if that's what you're trying to do

what the fuck is going on here

encode;
ffmpeg -i out.mp3 -ac 1 -ar 16000 -c:a pcm_u8 -f u8 - | ffmpeg -f rawvideo -pix_fmt yuv420p -r 60 -s 640x480 -i - -c:v libvpx -deadline best -cpu-used 0 -g 1 -qmin 18 -qmax 18 -y out.webm

decode;
ffmpeg -i out.webm -f rawvideo - | mpv --demuxer=rawaudio --demuxer-rawaudio-format=u8 --demuxer-rawaudio-rate=16000 --remuxer-rawaudio-channels=1 -

Attached: out.webm (640x480, 2.76M)

ps. my mp3 is 58 minutes long and 133MiB
yes, that's almost an hour of audio in 2 seconds of video

just noticed i posted a typo,
decode;
ffmpeg -i out.webm -f rawvideo - | mpv --demuxer=rawaudio --demuxer-rawaudio-format=u8 --demuxer-rawaudio-rate=16000 --demuxer-rawaudio-channels=1 -

Where can I find more ffmpeg commands like that ?

i've done a bunch similar to this from time to time on Jow Forums

Care to post again?

2MB

Used to be much larger, until Hiro

I said on HOW LONG, not size. Different boards have different size limits you mong.
a.4cdn.org/boards.json

just go on rbt.asia and search for "rawvideo", not all of them use it, but a bunch do
i haven't kept them, since i don't find them particularly difficult to write
