• .exe file, works different than .py file

  29 août 2024, par r_b

  I've made the YouTube Dowbloader App. Everything is working properly (run in PyCharm), but when I try to make it into an executable with pyinstaller, it does not work.

  


  This is the link to the repo :

  


  YouTube Downloader

  


  Command for making exe file :
pyinstaller project.spec

  


  project.spec file :

  


  # project.spec
# -*- mode: python ; coding: utf-8 -*-

block_cipher = None

a = Analysis(
    ['gui.py'],
    pathex=['.'],
    binaries=[],
    datas=[('static_files/*', 'static_files')],
    hiddenimports=[],
    hookspath=[],
    runtime_hooks=[],
    excludes=[],
    win_no_prefer_redirects=False,
    win_private_assemblies=False,
    cipher=block_cipher,
)
pyz = PYZ(a.pure, a.zipped_data, cipher=block_cipher)

exe = EXE(
    pyz,
    a.scripts,
    [],
    exclude_binaries=True,
    name='YouTube Downloader',
    debug=False,
    bootloader_ignore_signals=False,
    strip=False,
    upx=True,
    upx_exclude=[],
    runtime_tmpdir=None,
    console=False,
    icon='static_files/logo.ico'
)
coll = COLLECT(
    exe,
    a.binaries,
    a.zipfiles,
    a.datas,
    strip=False,
    upx=True,
    upx_exclude=[],
    name='YouTube Downloader'
)

app = BUNDLE(
    coll,
    name='YouTube Downloader',
    icon='static_files/logo.ico',
    bundle_identifier=None
)


  


  The file structure :

  


  project/
├── backend.py
├── gui.py
├── temp_mp3 # temporary mp3 for Audio player
├── static_files/
│   ├── icon.ico
│   ├── image1.png
│   ├── image2.png
│   └── setup.json  # setup.json file
└── project.spec

  After searching and fetching the YouTube URL, the app downloads an MP3 file (in temp_mp3) for the audio player section.

  


  And here is the difference between .exe and the .py, when I run .exe the APP downloads the audio segment from the URL in .webm format and stops there. Even if the format is different, it should be converted to MP3 (in PyCharm does).

  


  Find possible problem with moviepy/ffmpeg.exe (library for converting files).

  


  project.spec

  


  a = Analysis(
    ['gui.py'],
    pathex=['.'],
    binaries=[('C:\\path\\to\\ffmpeg\\bin\\ffmpeg.exe', 'ffmpeg')],
    datas=[('static_files/*', 'static_files')],


  


  Added binaries => path to ffmpeg.exe , but it still doesn't work.

  


• How create a circular video (transparent area on top of video) effect without applying image mask to video

  26 septembre 2024, par Arina Lubimova

  Basically i googled a lot and solutions suggests apply some PNG mask or do not provide needed solution.

  


  What i've found.

  


  ffmpeg -i main.mkv -i facecloseup.mkv
 -filter_complex "[1]trim=end_frame=1,
  geq='st(3,pow(X-(W/2),2)+pow(Y-(H/2),2));if(lte(ld(3),pow(min(W/2,H/2),2)),255,0)':128:128,
  loop=-1:1,setpts=N/FRAME_RATE/TB[mask];
  [1][mask]alphamerge[cutout];
  [0][cutout]overlay=x=W-w:y=0[v];
  [0][1]amix=2[a]"
 -map "[v]" -map "[a]"  out.mp4


  


  command = "-i " + this.video1Path.getPath() + " -i " + this.video2Path.getPath() + " -filter_complex [1]trim=end_frame=1,geq=lum_expr='st(3,pow(X-(W/2),2)+pow(Y-(H/2),2));if(lte(ld(3)," + (this.mZoomLayout.getZoomedWidth()/2) + "*" + (this.mZoomLayout.getZoomedWidth()/2) + "),255,0)':128:128,format=gray,loop=-1:1,setpts=N/FRAME_RATE/TB[mask];[1][mask]alphamerge,format=rgba,lutrgb=a=if(gte(val\\,16)\\,val)[cutout];[0][cutout]overlay=" + this.mZoomLayout.getCircleX() + ":" + this.mZoomLayout.getCircleY() + ":enable='between(t,0," + this.videoTwoDuration + ") -c:v libx264 -crf 24 -preset ultrafast " + videoPath.getPath(); 


  


  So i tried to extract needed things from them, but i don't understand how exactly i need to do that, i did this :

  


  ffmpeg -i video.mp4 -filter_complex "[0]geq='st(3,pow(X-(W/2),2)+pow(Y-(H/2),2));if(lte(ld(3),pow(min(W/2,H/2),2)),255,0)':H:W; [0:v][mask]alphamerge" out.mp4


  


  [mov,mp4,m4a,3gp,3g2,mj2 @ 000001f761dd8e40] Invalid stream specifier: mask.

  ffmpeg -i video.mp4 -filter_complex "[0]geq=lum_expr='st(3,pow(X-(W/2),2)+pow(Y-(H/2),2));if(lte(ld(3),pow(min(W/2,H/2),2)),255,0)':H:W; [0:v][mask]alphamerge" out.mp4

  And one more time, guys, if you are going to post some "prepared image mask" solution - just leave, the question is about creating mask on air.

  


  So, let's say we have red square (yes, ratio is static, always 1:1), yes, i can't post it because i dont have 10 rep. (...).

  


  https://i.sstatic.net/MsL71.png - red square.

  


  https://i.sstatic.net/aIFEV.png - circle

  


  https://i.sstatic.net/R8EAx.png - result

  


  https://i.sstatic.net/WtqQg.png - final result

  


  I actually want to get the answer from @Gyan or @llogan because i searched a lot and only these two guys do understand how to make things programmatically.

  


  More tech details :
Aspect ratio is constant - 1:1, width and height should be taken from the video in auto way, we need to create a white square with transparent circle inside it, the end result must contain "rounded" video with white background.

  


• Crop a video in Python, centered on a 16x9 video, cropped to 9x16, moviepy ?

  22 décembre 2022, par Levfo

  I want to crop a video that is 16x9 resolution to 9x16. This can be done by cropping a centered 607px wide rectangle on the 16x9 video. Can this be done ? EDIT : I do not care to stay within moviepy. I want to use something with speed. Currently, writing a 5 min video file with moviepy is taking 10+ minutes.

  


  

  


  from moviepy.video.io.ffmpeg_tools import ffmpeg_extract_subclip
import moviepy.editor as mpy

origVideo = 'video.mp4'
video = mpy.VideoFileClip(origVideo)

#Crop 'video' here and output 'cropped-video.mp4'

video.write_videofile('video-cropped.mp4')


  


  Currently only getting a black screen with no audio. The video won't play, but it has a time code.
