• Having issues making an app with py2app ffmpeg and ffprobe

  23 septembre 2024, par Nuno Mesquita

  I have made an app in OSX Python, that uses FFMEG and ffprobe.

  


  It runs fine in my VS Code.

  


  I want to make a self sustained app, that others can use, without needed to install anything themselves. So, I manually included the static libraries in the bin folder of my main app, and am able to run the app using the libraries inside my bin folder.

  


  I have lost many hours trying to figure this out, and am always getting the same error.

  


  My best shot was being able to open the app inside app/contents/resources and running via Python, but still have the issue saying that ffprobe is not available.

  


  I´m losing my mind...

  


  Should I try a completely different approach ?

  


  For now, I just want my OSX friends to be able to use the app, then I will want it to run on Windows too, but baby steps.

  


  I am not quite sure what to include in setup.py, so I would love to include everything that is in my app folder, to avoid all sorts of errors in missing .pngs and stuff.

  


  I also made sure that libraries are executable (they are about 80MB each (ffmpeg and ffprobe))

  


  Can anyone help =D ???

  


  I described above, tested different ways, checked stuff like redirecting the libraries to the folders of the app :

  


  For the last try my setup.py was :

  


  from setuptools import setup

APP = ['mpc.py']
DATA_FILES = [
    ('bin', ['./bin/ffmpeg', './bin/ffprobe']),
    ('theme/dark', ['./theme/dark/*.png']),
    ('theme/light', ['./theme/light/*.png']),
    ('theme', ['./theme/dark.tcl', './theme/light.tcl']),
    '.',  # Add current directory to ensure everything is included
]

OPTIONS = {
    'argv_emulation': False,
    'packages': ['pydub', 'pygame', 'requests', 'freesound'],
    'includes': ['pydub', 'pygame', 'requests', 'freesound'],
    'resources': ['./bin/ffmpeg', './bin/ffprobe', './theme/dark/*.png', './theme/light/*.png',     './theme/dark.tcl', './theme/light.tcl'],
}

setup(
    app=APP,
    data_files=DATA_FILES,
    options={'py2app': OPTIONS},
    setup_requires=['py2app'],
)


  


  And I also had this in the beginning of my Python script :

  


  # Set ffmpeg and ffprobe paths relative to the app's Resources/bin directory
app_dir = os.path.dirname(os.path.abspath(__file__)) 

# Set ffmpeg and ffprobe paths relative to the app's Resources/bin directory
ffmpeg_path = os.path.join(app_dir, 'bin', 'ffmpeg')
ffprobe_path = os.path.join(app_dir, 'bin', 'ffprobe') 
AudioSegment.converter = ffmpeg_path
AudioSegment.ffprobe = ffprobe_path


  


  Don't know what else to try.

  


• ffmpeg convert images to video and add audio in one command

  9 novembre 2022, par user2108258

  I have two commands that I would like consilidate to a 1 liner.
Here are the two queries.

  


  Here are the steps i need help

  


  

  1. create a video based on a directory of jpegs

  


  


  ffmpeg -f image2 -pix_fmt yuv420p -r 10 -s 1080x1920 -i 'Roach spray high-25263/%d.jpg' -vf "pad=ceil(iw/2)*2:ceil(ih/2)*2" -crf 25 -vcodec h264 'Roach spray high.mp4' -y


  


  

  2. Merge audio with video from step 1

  


  


  ffmpeg -stream_loop -1 -i 'Roach spray high.mp4' -i '/beats/2022/Roach spray high.mp3' -shortest -map 0:v:0 -map 1:a:0 '/videos/Roach spray high/Roach spray high.mp4' -y


  


  Is there a way to combine these two steps into 1 ?

  


• FFMPEG convert GIF to MP4 is cutting GIF short

  31 août 2019, par Jay

  I have this command line to run ffmpeg from aws lambda.

  The code is suppose to convert a GIF to a black background mp4.

  On my local PC it works perfectly.

  For whatever reason the ouput out of AWS Lambda is missing some of the GIF frames.

  Any Ideas ?????

  I have checked to make sure /tmp/2.gif is an accurate input and it is.

  os.system("/tmp/ffmpeg -f lavfi -i color=black -i /tmp/2.gif -movflags faststart -pix_fmt yuv420p  -filter_complex  '[0][1]scale2ref[bg][gif];[bg]scale=2*trunc(iw/2):2*trunc(ih/2),setsar=1[bg];[bg][gif]overlay=1' -c:v libx264 -preset veryslow  /tmp/black.mp4")
