• ffmpeg arguments for youtube upload [duplicate]

  9 March, by Hoopes

  I'm currently having an issue in my ios app where youtube sharing of a video created by ffmpeg seems broken. I am starting with an audio file, and an image that I will use as the static background of the video.

  


  ffmpeg -y 
-i "/path/to/audio.m4a" 
-r 24 
-i "/path/to/background.png" 
-codec:a aac_at 
-codec:v h264_videotoolbox 
-brand mp42 
-vf "scale=1080:1080" 
-vf "scale=out_color_matrix=bt709" 
-color_primaries bt709 
-color_trc bt709 
-colorspace bt709 
-movflags +faststart 
"output.mp4"


  


  Note that since i'm on an ios device, i am using h264_videotoolbox, which uses the apple hardware to help encode it.

  


  When I use the regular ios share screen, and share to something like slack, the video seems to work fine. However, when I try to share to youtube via the same share screen, it looks like it can't detect the duration of the video:

  


  

  


  Another thing to note is that when i download the file, and upload it to youtube via regular web browser, it seems to be fine - which somewhat points to it not being ffmpeg related, but it shares fine to other apps.

  


  I'm using ffmpeg version 5.1.2

  


• C# (discord music bot) Youtube to mp3 api with ffmpeg

  4 October 2017, by Greg Varadi

  Ok, so i have made a discord music bot before with youtube-dl in C#. But I don’t like it because it’s very slow. It has to download the song and then stream it using ffmpeg to discord. I don’t know but I think there is a quicker way.

  So, i decided to use a youtube to mp3 api to get a mp3 as quick as possible, but it won’t work. I mean I found an api that worked, but it’s the worst api I ever seen. This is the api: http://www.convertmp3.io/api/ . Sometimes doesn’t give the mp3, just a link to a download page that doesn’t work.

  I’m still searching for an api. Last time I found this:
  http://www.yt-mp3.com/fetch?v=VIDEO-ID&apikey=1234567
  This is for me the best. But ffmpeg doesn’t recognize the mp3. And I don’t know why because I can’t see any difference beetween them. Of course it’s probably something different but I can’t see what. And I don’t even know that ffmpeg will recognize any of these api’s mp3 files, but it’s working with this convertmp3.io api.

  So, my question is, is there someone who did something like this or someone who can give me advice?

  By the way, I want something that is as quick as oxyl- or hime bot. And I know that using apis for getting mp3 from youtube videos is not by all means the most legal thing, because the copyright and stuff, but yeah... This is the only way, I think.

• How can I schedule a YouTube livestream entirely from Linux?

  25 April 2021, by Dale Wellman

  I have a setup on a Raspberry Pi (with its native camera) that uses a cronjob to start an ffmpeg session with its output streaming to YouTube. I re-use the same stream key each time, which is written into my ffmpeg scripts. This all works perfectly each week, automatically starting and stopping at the desired time.
However, each week PRIOR to that livestream, I have to "manually" go into YouTube Studio and "schedule" a new future event. This is easy enough, since it lets me "reuse" previous settings — all I have to change is the Title, date, and time. But I would love to figure out a way to automate that part of the process, as well. I assume it involves using the YouTube Data API, but I'm not well versed in API's, JSON, etc.
(I do have a strong Linux background, bash scripting skills, and general programming background.)

  


  My final solution just needs to:

  


  

  • create the new scheduled event (maybe 12 hours prior to going live), with Title, Date, Time, "Unlisted" status, category, and so forth — all the usual settings I do manually within Studio

  


  • retrieve the assigned URL for the upcoming stream (my script will then email that to me)

  


  


  So, basically, I'm asking for help getting started with the API, or whatever method is capable of doing this. I would prefer to code it on the same Pi that does the ffmpeg encoding (although in a pinch, I could create the schedule from another computer, even Windows). Any examples would be great.

  


  So far, all I have done is create my Google project, enable the YouTube Data API in the project, and create my API key. But I'm not sure where to go from there.
