• FFMpeg command output shows 'green pixelated' video

  18 janvier 2021, par DonX

  I am trying to take a single image and add audio resulting in a video playing the entire song with that single image ; much like you see for YouTube videos for songs. The command I am using is from this link : https://askubuntu.com/questions/868283/image-audio-mp4-how-to-make-video-smaller

  


  This is the command :

  


  ffmpeg -loop 1 -framerate 1 -i image.png -i song.aac -c:v libx264 -preset veryslow -crf 0 -c:a copy -shortest output.mp4


  


  It works as intended for having the video file be a small size, and the song plays as well, but depending on the image I used, some of the images appear 'Green' when playing the video.

  


  However though, this command works for any image used :

  


  ffmpeg -loop 1 -framerate 1 -i image.jpg -i music.mp3 -c copy -shortest output.mp4


  


  But the result is a very big file whereas I would like it to be smaller. Any help would be greatly appreciated ! Thank you !

  


  FFMpeg version : 4.3.1

  


• Issues with MediaSourceExtension

  4 janvier 2023, par engine32

  I want to livestream audio only using MSE. I would like to send data/files via websockets, therefore no HLS nor DASH.

  


  But until I implement websockets, I thought to give it a try by statically loading the song in an array.

  


  Here is my code so far :

  


  <audio controls="controls"></audio>&#xA;..&#xA;<code class="echappe-js">&lt;script&gt;&amp;#xA;  const ms = new MediaSource();&amp;#xA;  var ae = document.getElementById(&quot;ap&quot;);&amp;#xA;  ae.src = URL.createObjectURL(ms);&amp;#xA;  ms.addEventListener(&amp;#x27;sourceopen&amp;#x27;, msOpen);&amp;#xA;  &amp;#xA;function msOpen(e) {&amp;#xA;  URL.revokeObjectURL(ae.src);&amp;#xA;  var mse = e.target;&amp;#xA;  const sourceBuffer = mse.addSourceBuffer(&amp;#x27;audio/mp4&amp;#x27;);&amp;#xA;  var u8A0 = new Uint8Array([0x00, 0x00, 0x00, 0x1C, 0x66, ...]);&amp;#xA;  sourceBuffer.appendBuffer(u8A0.buffer);&amp;#xA;  &amp;#xA;  sourceBuffer.addEventListener(&amp;#x27;updateend&amp;#x27;, function() {&amp;#xA;    if (!sourceBuffer.updating &amp;amp;&amp;amp; mse.readyState === &amp;#x27;open&amp;#x27;) {&amp;#xA;      mse.endOfStream();&amp;#xA;      console.log(&amp;#x27;Audio is ready to play!&amp;#x27;);&amp;#xA;    }&amp;#xA;  });&amp;#xA;}  &amp;#xA;&lt;/script&gt;&#xA;&#xA;

  


  The result is that there are no errors in the debug window and the audio element correctly shows the duration of the song, about two min and half. However, once I click Play, the duration shows 0 (zero) and the song is not played. If I try to pause and play again, the debug window says :

  


  *"Uncaught (in promise) DOMException : The fetching process for the media resource was aborted by the user agent at the user's request".
*
This is the ffmpeg command I used to prepare the file :

  


  ffmpeg -i m.wav -c:a aac -b:a 32k -f mp4 output.mp4

  


  Any help would be well appreciated.
Thank you.

  


• Error opening input files : Invalid data found when processing input

  I am creating disnake music bot. The error is :

  


  [in#0 @ 00000233f8d71500] Error opening input: Invalid data found when processing input
Error opening input file https://www.youtube.com/watch?v=duDUqBtxwXk.
Error opening input files: Invalid data found when processing input


  


  Here is part of my code :

  


  import disnake
import asyncio
from yt_dlp import YoutubeDL
import ffmpeg


YTDL_OPTIONS = {'format': 'bestaudio', 'noplaylist': 'False', 'simulate':'True', 'key':"FFmpegExtractAudio"}
FFMPEG_OPTIONS = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}


async def play_music(inter):
        global YDTL_OPTIONS, FFMPEG_OPTIONS
    print(tm.now().strftime("%H:%M:%S"),"play_music begin")
    id = int(inter.guild.id)
    with YoutubeDL(YTDL_OPTIONS) as ydl:
        info = ydl.extract_info(url, download=False)

    song = {
            'link': 'https://www.youtube.com/watch?v=' + url,
            'thumbnail': 'https://i.ytimg.com/vi/' + url + '/hqdefault.jpg?sqp=-oaymwEcCOADEI4CSFXyq4qpAw4IARUAAIhCGAFwAcABBg==&rs=AOn4CLD5uL4xKN-IUfez6KIW_j5y70mlig',
            'source': info['formats'][0]['url'],
            'title': info['title']
        }   self.vc[id].play(disnake.FFmpegPCMAudio(executable=r"C:\\ffmpeg\\ffmpeg\\bin\\ffmpeg.exe",source=song["source"], **FFMPEG_OPTIONS))
    print(tm.now().strftime("%H:%M:%S"),"play_music end")


  


  I tried to write source = song['source'] instead of source = song['link'], but it didn't seem helpful.
