  I'm trying to upload a video on S3 service using Laravel FFMPEG and convert the video to multi-resolution after adding Frames, the error appears on the server, but on localhost not appear, and working very well locally.

  


  `FFMpeg::fromDisk('s3')//uploads
    ->open($this->data["storage_path_full"])
        ->exportForHLS()
        ->addFormat($lowBitrate, function ($media) {
            $media->addFilter('scale=256:144'); 
        })
        ->addFormat($superLowBitrate, function ($media) {
            $media->addFilter('scale=426:240'); 
        })
        ->addFormat($midBitrate, function ($media) {
            $media->addFilter('scale=480:360'); 
        })
        ->addFormat($superMidBitrate, function ($media) {
            $media->addFilter('scale=640:480'); 
        })
        ->addFormat($highBitrate, function ($media) {
            $media->addFilter('scale=1280:720'); 
        })
        ->addFormat($superHighBitrate, function ($media) {
            $media->addFilter('scale=1920:1080'); 
        })
        ->toDisk('s3')
        ->save($this->data["storage_path_video"]);`


  


• PyDub can't locate FFmpeg, even after comfirming that FFmpeg is properly installed

  14 avril 2023, par TordG

  After trying many solutions, checking that FFmpeg is installed correctly through cmd and other modules, PyDub still cannot find it. I am running Windows 11, Python 3.10.6, PyDub 0.25.1 and FFmpeg version 2023-04-12-git-1179bb703e-full_build-www.gyan.dev

  


  I've tried to run the following code that should speed up an mp3 file within the directory by 100%

  


  import os
from pydub import AudioSegment

file = r'test.mp3'

# Load the MP3 file
audio = AudioSegment.from_file(file, format="mp3")

# Increase the speed
audio = audio.speedup(playback_speed=2, chunk_size=150)

# Export the modified file to the same file name
audio.export(file, format="mp3")

# Delete the original file
os.remove(file)


  


  From this I get the following error :

  


  C:\Users\xxx\AppData\Local\Programs\Python\Python310\lib\site-packages\pydub\utils.py:170: RuntimeWarning: Couldn&#x27;t find ffmpeg or avconv - defaulting to ffmpeg, but may not work&#xA;  warn("Couldn&#x27;t find ffmpeg or avconv - defaulting to ffmpeg, but may not work", RuntimeWarning)&#xA;C:\Users\xxx\AppData\Local\Programs\Python\Python310\lib\site-packages\pydub\utils.py:198: RuntimeWarning: Couldn&#x27;t find ffprobe or avprobe - defaulting to ffprobe, but may not work&#xA;  warn("Couldn&#x27;t find ffprobe or avprobe - defaulting to ffprobe, but may not work", RuntimeWarning)&#xA;Traceback (most recent call last):&#xA;  File "c:\Users\xxx\xxx\xxx\xxx\xxx\speed_up.py", line 7, in <module>&#xA;    audio = AudioSegment.from_file(file, format="mp3")&#xA;  File "C:\Users\xxx\AppData\Local\Programs\Python\Python310\lib\site-packages\pydub\audio_segment.py", line 728, in from_file&#xA;    info = mediainfo_json(orig_file, read_ahead_limit=read_ahead_limit)&#xA;  File "C:\Users\xxx\AppData\Local\Programs\Python\Python310\lib\site-packages\pydub\utils.py", line 274, in mediainfo_json&#xA;    res = Popen(command, stdin=stdin_parameter, stdout=PIPE, stderr=PIPE)&#xA;  File "C:\Users\xxx\AppData\Local\Programs\Python\Python310\lib\subprocess.py", line 969, in __init__&#xA;    self._execute_child(args, executable, preexec_fn, close_fds,&#xA;  File "C:\Users\xxx\AppData\Local\Programs\Python\Python310\lib\subprocess.py", line 1438, in _execute_child&#xA;    hp, ht, pid, tid = _winapi.CreateProcess(executable, args,&#xA;FileNotFoundError: [WinError 2] The system cannot find the file specified&#xA;</module>

  


  I've added FFmpeg to my path variable and checked that it worked by typing 'ffmpeg' in my command prompt. I also made sure that it was installed and pathed correctly by testing it with other modules that should use ffmpeg as well

  


  The following code worked flawlessly (where moviepy uses ffmpeg as far as I know) :

  


  from moviepy.editor import ColorClip

# Create a black clip with a duration of 5 seconds
empty_clip = ColorClip(size=(640, 480), color=(0, 0, 0), duration=5)

# Write the empty clip to a video file
empty_clip.write_videofile("empty.mp4", codec="libx264", fps=25)



  


  I've specified the abs path in my code as :

  


  AudioSegment.ffmpeg_path = r"C:\ffmpeg\bin\ffmpeg.exe"

  


  Again this didn't work and I cannot find any more solutions anywhere

  


• FFMPEG Streaming Issue - "Connection Failed : I/O Error"

  25 avril 2023, par 1080Jake

  For a fun project I wanted to see if I could create an SRT stream from an active SDI input (1080i59.94) on a BMD Decklink Quad card. Whenever I try to execute my syntax, I get the following prompt "Connection to srt ://127.0.0.1:1234 failed : I/O error"
Is there anyway to use a debug mode and get more details about what is causing this ? I am very new to FFMPEG and obviously clueless. This is the syntax I am trying to execute -

  


  C:\Users\01>ffmpeg -f decklink -i "DeckLink Quad (8)" -c:v libx265 -preset ultrafast -b:v 5000k -f mpegts srt://127.0.0.1:1234


  


  Full printout here -

  Instead of using an SDI input from my BMD card, I also tried to use a local mp4 file on my PC but I get the same prompt. Note - I am running FFMPEG on a Windows 10 PC.
