[FFmpeg-devel] [Consulting] Converting an Audio Visualization application to CLI using FFMpeg

[Ryan Schott]

Hello,

I am not sure if this is the right page to post this, but your consulting
page recommended I use this list. I recent built an audio visualization app
using html5. I'm currently using that app with xsplit to stream music to an
RTMP endpoint on either twitch.tv or YouTube.

For an example check out: https://youtu.be/Zmb_fy528Uo

I would like to be able to mimic this functionality on a server without
using window capture and a live browser window. I'm a fan of the
flexibility that my html5 solution gives me, but there's no way to spawn
streams from a CLI. I know I will most likely have to throw out my HTML5
solution to get the data to something that can run on a command line
without a full browser.

My dream is that I can somehow stream the audio and video that would be
coming from the browser normally to an input in ffmpeg and then output it
to an RTMP endpoint. If I could get to that point, I could easily build a
controller application with my skillset to allow any number of users to
arbitrarily stream music with visualization from our central server to
their twitch and youtube channels.

Another use case I have is mass creating visualized mp4's from mp3's. I
currently have  a static image script working using ffmpeg to batch create
videos from mp3's, but we'd rather have visualized videos than static image
videos.

Overall, I'm looking to see if it's feasible to pipe the html5 video and
audio output to an rtmp endpoint without a browser, and if it's not what my
options are to construct visualizations in code without a desktop.

thanks,
