• ffmpeg datascope filter : How does it works ?

  25 octobre 2022, par tony

  I'm trying to see how the datascope filter is displaying the color values for a black and white image. I was expecting to see a part of the image with 0xfff and one with 0x000 value,
instead I obtained only the 0xfff for white

  


  ffmpeg \
-f lavfi -i color=white:100x100 \
-f lavfi -i color=black:100x100 \
-lavfi '[0:v][1:v]hstack[out]' \
-map [out] \
-frames 1 \
blackAndWhite.png ; \


ffmpeg \
-i blackAndWhite.png \
-vf 'datascope' \
data.png


  


  what am I seeing ?


  


• Pyinstaller exe works halfway on another computer

  5 novembre 2022, par At Bay

  I wrote a code which uses FFMPEG and os, subprocess, datetime, speechrecognition, and xlsxwriter libraries. Below a brief sketch of the code - it goes through a directory of wav files and creates a transcription for X seconds in length and saves it into an excel sheet.
import os
import subprocess
import datetime
import speech_recognition as sr
import xlsxwriter

  


  def ffmpeg():
   #create clip
   subprocess.run(["ffmpeg", "-ss", starti, "-t", lengthi, "-i", filepathO, filepathNEW1])

   #convert to mono
   subprocess.run(["ffmpeg", "-i", filepathNEW1, "-ac", "1", filepathNEW2])
   
   #compres to 44.1 kHZ
   subprocess.run(["ffmpeg", "-i", filepathNEW2, "-ar", "44100", filepathNEW3])

def transcription():
    with sr.AudioFile(os.path.abspath(clippath)) as source:
       audio = r.record(source)  # read the entire audio file
       transcriptstring = str(r.recognize_google(audio, language = 'en', show_all=True))
       worksheet.write(tcol, transcriptstring)


#call functions in this order
for filename in os.listdir(ufolder):
   if (filename.endswith(".wav")):
       ffmpeg() #cuts clips, compresses to mono and 44.1 khz
       transcription() 

workbook.close()



  


  When I try to run the exe created by pyinstaller, I get the following error :

  


  Enter directory of wav files: C:\Users\myname\Downloads\&#xA;Enter clip start (seconds): 0&#xA;Enter desired clip length (seconds): 5&#xA;Traceback (most recent call last):&#xA;  File "cliptranscript.py", line 134, in <module>&#xA;  File "cliptranscript.py", line 47, in ffmpeg&#xA;  File "subprocess.py", line 503, in run&#xA;  File "subprocess.py", line 971, in __init__&#xA;  File "subprocess.py", line 1440, in _execute_child&#xA;FileNotFoundError: [WinError 2] The system cannot find the file specified&#xA;[13304] Failed to execute script &#x27;cliptranscript&#x27; due to unhandled exception!&#xA;</module>

• My discord music bot works locally, but not on a server [closed]

  8 décembre 2022, par Asmondya

  I have an issue with my discord music bot that I made with discord.js v14.

  


  When I run it locally, it works fine and plays music as it should. But when I put in on a server (here I use Vultr), it doesn't work.

  


  I am not sure but it might come from FFmpeg. I am kinda desperate and cant really figure where the issue is from. I think it is FFmpeg because it is what converts the music.

  


  What happens :

  


  Me: !play a music
Bot: Now playing a music
*and right after, without playing the music*
Bot: Music finished


  


  What should normally happen is that same thing but the "music finished" should be sent when the queue is finished.

  


  The thing is that the bot works perfectly locally, but does this when it is hosted on a server. Also I don't have any error messages or else. It just doesn't play the music like if the music was 0 seconds length.

  


  I tried making sure everything is installed on the server, same as making sure ffmpeg was installed globally and I have the good version of it. Here is the answer I have to the "ffmpeg -version" command :enter image description here.

  


  Does anyone know what could be the issue or what could cause it ? I can show some code if needed, even tho it works perfectly fine locally.

  


  Here's my code :

  It does come from my ffpmeg, I need to install one of these packages instead of the npm installation : https://github.com/BtbN/FFmpeg-Builds/releases

  


  How do I install it on a server (Vultr) ?
