• C# - Discord.Net - Trying to read audio from soundcloud and transmit it to discord

  28 mars 2022, par Bruno Braga

  I am currently working on a discord bot that is able to play a song using soundcloud.
Unfortunately, I can't seem to figure out how to get it to read from the url and stream it !
The bot it made in C#, and uses Discord.net library and ffmpeg for the audio.
Would love to hear some suggestions !

  


  These are the three functions involved :

  


  [Command("teste", RunMode = RunMode.Async)]
public async Task Play(IVoiceChannel channel = null)
{
    var audioClient = await JoinChannel(channel);
    var url = "https://soundcloud.com/campatechlive/campatech-live-feat- 
        matheus-moussa-arabian-system-vol-2-psy-trance-150-original-mix";

    var ffmpeg = new Ffmpeg(audioClient);
    await ffmpeg.SendAsync(url);
}

public async Task SendAsync(string path)
{
    using (var ffmpeg = CreateStream(path))
    using (var output = ffmpeg.StandardOutput.BaseStream)
    using (var discord = _client.CreatePCMStream(AudioApplication.Mixed))
    {
        try { await output.CopyToAsync(discord); }
        finally { await discord.FlushAsync(); }
    }
}

private Process? CreateStream(string path)
{
    return Process.Start(new ProcessStartInfo
    {
        FileName = "ffmpeg",
        Arguments = $"-hide_banner -loglevel panic -i \"{path}\" -ac 2 -f 
        s16le -ar 48000 pipe:1",
        UseShellExecute = false,
        RedirectStandardOutput = true,
    });
}


  


  I'm guessing it's something on the ffmpeg arguments, but can't kind of figure out what.

  


  I've tried a bunch of different arguments on ffmpeg, but none of them worked.
Anyone can lend me a hand ?

  


• Overlay a video and an image over a background video and shift that background video's position to the right

  4 août 2023, par sybr

  I'm currently working on a way to improve my production process for the videos that I'm making. I usually edit videos using two folders full of clips. Being able to automate putting these together in Premiere would save me a lot of time.

  


  I'm using the FFMpegCORE C# library, as well as Xabe.FFMpeg to achieve what I'm trying to do, and I've currently reached the point of creating two separate videos using the clips I mentioned earlier.

  


  The final step that I need to solve is to overlay the overlay video (overlay.mp4) over the background video (background.mp4), add an overlay image to add a clean divider (overlay.png) between the edges of the videos, and to somehow shift the position of the background video 33% to the right (background.mp4).

  


  This is the script I've come up with so far :

  


  ffmpeg -i overlay.mp4 -i background.mp4 -i overlay.png -filter_complex \ 
"[1:v]scale=608:1080[a]; [0:v]pad=1920:1080[b]; [b][a]overlay[out]; \
[out][2:v]overlay[out]; [0][1]amix[a];" \
-map [out] -map [a] -c:v libx264 -crf 30 -pix_fmt yuv420p -y output.mp4


  


  Is there a way to shift the background video to the right ? Or should I manually edit the video files ?

  


  Would love some help here, also eager to learn more about FFmpeg, so some explanation would be highly appreciated !

  


  Edit :

  


  Just found the solution, padding the background video for 33% and then cropping the final out back to 1920x1080 seemed to do the trick !

  


  ffmpeg -i overlay.mp4 -i background.mp4 -i overlay.png -filter_complex "[1:v]scale=608:1080[a]; [0:v]pad=2560:0:x=1920:y=1080[b]; [b][a]overlay[out]; [out][2:v]overlay[out]; [out]crop=1920:1080:0:0[out]; [0][1]amix[a];" -map [out] -map [a] -c:v libx264 -crf 30 -pix_fmt yuv420p -y output.mp4


  


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

  25 avril 2021, par 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.
