• Compile FFmpeg project for ARM in PC Linux 64-bit

  4 avril 2017, par Dang_Ho

  I want to compile a simple FFmpeg project for my Arrow Sockit Board with an arm-linux-gnueabihf architecture from my Linux-64bit PC. I don’t want to compile the project in the board directly because of my low CPU and that is not convenient for me.

  I’m using FFmpeg version 2.8.11 and this is my Makefile and my "main.c". I know, my Makefile has something wrong in it. If I command "make", it will compile depending on my PC’s architecture, I can’t use that binary file on my board. So, can someone please tell me how to do it.

  I Cross-Compiled the FFmpeg package and installed into the board. I tested all functions such as ffmpeg, ffplay. All them work. The source code folder is located to /home/hohaidang/ffmpeg-2.8.11

          av_register_all();
  
          return 0;

• Getting error while transcribing mp3 file into text file

  8 août 2021, par Parul Verma

  I used the below code to transcribe the mp3 file into text.

  


  import speech_recognition as sr
from pydub import AudioSegment

# convert mp3 file to wav  
src=(r"C:\Users\user.name\Desktop\python\DATA\Audio files\Audio1.mp3")
sound = AudioSegment.from_mp3(src)
sound.export(r"C:\Users\user.name\Desktop\python\DATA\Audio files\Audio1.wav"), format="wav")

file_audio = sr.AudioFile(r"C:\Users\user.name\Desktop\python\DATA\Audio files\Audio1.wav")

# use the audio file as the audio source                                        
r = sr.Recognizer()
with file_audio as source:
 audio_text = r.record(source)

print(type(audio_text))
print(r.recognize_google(audio_text))


  


  But I got the following error-

• My discord.py music bot fails with "ffmpeg not found"

  17 avril 2022, par ThatNoClueDude

  I am using repl.it to host my Discord.py music bot
It fails with an error saying "ffmpeg is not found"
I used multiple ways to fix the error

  


  npm install ffmpeg-static in shell is my first way how i tried to fix the problem, but it did not do anything.

  


  Even if i do any way, repl.it will still give the error ffmpeg not found.
Can someone please tell any way to fix this issue ??
