• Discord FFMPEG audio wont play from yt-dlp

  19 mars 2023, par user21236822

  My question is this : Why isn't my bot playing audio ?

  


  I want the bot to join, play audio from queue, then disconnect without downloading an mp3 file.

  


  I tried using youtube-dl, but I switched to the yt-dlp library after getting errors I couldn't fix.
I am running on Windows 10 locally. All my libraries are up to date.

  


  Here are my ydl_opts and FFMPEG_OPTS :

  


  ydl_opts = {
    'format': 'bestaudio/best',
    'postprocessors': [{
        'key': 'FFmpegExtractAudio',
        'preferredcodec': 'mp3',
        'preferredquality': '192',
    }],
}

FFMPEG_OPTIONS = {
    'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5',
    'options': '-vn'
} 


  


  Here is where I believe the problem is.

  


  async def play():
    print("Play Called")
    musicPlay()
    # Get message object from initial request
    message = ytLinkQue.get()
    print(f"Message object recieved: {message}")
    voiceChannel = message.author.voice.channel
    vc = await voiceChannel.connect()
    songsPlayed = 0
    
    while not ytLinkQue.empty():
        # Get current song
        currentSong = ytLinkQue.get()[0]
        print(f"Current song: {currentSong}")

        # Get song from Youtube
        with yt_dlp.YoutubeDL(ydl_opts) as ydl:
            # song = ydl.download(currentSong)
            info = ydl.extract_info(currentSong, download=False)
            song = info['formats'][0]['url']

        # Play Song
        vc.play(discord.FFmpegPCMAudio(song, **FFMPEG_OPTIONS), after=lambda e: print('Song done'))

        # Wait until the song has finished playing
        while vc.is_playing():
            print("playing rn")
            await asyncio.sleep(1)
    
    await vc.disconnect()
    musicStop()


  


  When play() is called, here is the output in terminal with my annotations as **** text **** :

  On Discord's end, the bot successfully connects then disconnects after 2 second.

  


  Note : I've only included code I think is relevant. Please let me know if I should add anything else to the post, otherwise, here is the github for the project. Code is in main.py.

  Thank you in advance !

  


  I've applied the advice from these posts but it still will not play audio :

• Rotating gyro data in gopro footage with ffpmeg

  2 juillet 2023, par FPV Shenanigans

  I believe orientation of gyro data in some of my gopro clips is wrong. Reelsteady runs stabilization ok but it results in even worse than initial video shaky effect. I have filmed with gopro in 90 degree with orientation locked .

  


  Is it possible to amend metadata if ffmpeg to fix this ?

  


  the below is an example clip

  


  Metadata :
major_brand : isom
minor_version : 512
compatible_brands : isomiso2mp41
encoder : Lavf60.10.100
Duration : 00:04:30.22, start : 0.000000, bitrate : 119132 kb/s
Stream #0:00x1 : Video : hevc (Main 10) (hvc1 / 0x31637668), yuv420p10le(pc, bt709), 3840x3360 [SAR 1:1 DAR 8:7], 118934 kb/s, 59.94 fps, 59.94 tbr, 60k tbn (default)
Metadata :
handler_name : GoPro H.265
vendor_id : [0][0][0][0]

timecode : 13:27:43:05
Side data :
displaymatrix : rotation of -90.00 degrees
Stream #0:10x2 : Audio : aac (LC) (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 189 kb/s (default)
Metadata :

vendor_id : [0][0][0][0]
Stream #0:20x3 : Data : none (tmcd / 0x64636D74)
Metadata :
handler_name : GoPro H.265
timecode : 13:27:43:05

  


  tried this

  


  ffmpeg.exe -i "F :\2023 THE ONLY COPY\Chasing surfers\GX010223.MP4" -c copy -metadata:s:v rotate=90 "F :\2023 THE ONLY COPY\Chasing surfers\GX010223_test.mp4"

  


  but reelsteady can't read metadata from a new video

  


• Using aler9/rtsp-simple-server, able to stream HLS from file but not from ffmpeg's stdin

  11 avril 2023, par Powercoder

  UPD : hehe, it actially works, but in chrome, not mozilla

  


  I want to display programmatically generated stream on a webpage in real time. For this I have rtsp-simple-server with RTSP and HLS enabled. I managed to publish a stream from file with command ffmpeg -re -stream_loop -1 -i file.mp4 -vcodec libx264 -f rtsp -rtsp_transport tcp rtsp://localhost:8554/mystream and see it at http://localhost:8888/mystream.

  


  But when I'm trying to do the same with python from the ffmpeg's stdin, I'm getting infinitely loading video instead of stream and browser console says "Uncaught (in promise) DOMException : The fetching process for the media resource was aborted by the user agent at the user's request". Here is my code :

  


  import random
import shlex
import subprocess
import time

import numpy as np


def main():
    width = 1024
    height = 720
    framerate = 1
    frame_duration = 1 / framerate
    cmd = shlex.split(
        f'ffmpeg'
        f' -y'
        f' -f rawvideo'
        f' -vcodec rawvideo'
        f' -s {width}x{height}'
        f' -pix_fmt bgr24'
        f' -r {framerate}'
        f' -i -'
        f' -r {framerate}'
        f' -force_key_frames expr:eq(mod(n,3),0)'
        f' -vcodec libx264'
        f' -crf 18'
        f' -preset ultrafast'
        f' -tune zerolatency'
        f' -f rtsp'
        f' -rtsp_transport tcp'
        f' rtsp://localhost:8554/mystream'
    )
    ffmpeg_process = subprocess.Popen(cmd, stdin=subprocess.PIPE)
    try:
        while True:
            image = np.full(
                (height, width, 3),
                (
                    random.randint(0, 255),
                    random.randint(0, 255),
                    random.randint(0, 255),
                ),
                dtype=np.uint8,
            )
            ffmpeg_process.stdin.write(image.tobytes())
            time.sleep(frame_duration)
    finally:
        ffmpeg_process.stdin.close()
        ffmpeg_process.wait()


if __name__ == '__main__':
    main()



  


  In the server's logs seems like no bad messages instead of single 404 status (is it just about favicon, right ?)

  How do I get my stream from python visible on a webpage ?
