• OSError : [WinError 6] The handle is invalid Python 3.10 Windows moviepy

  21 mars 2024, par ernesto casco velazquez

  I'm trying to make a clip using MoviePy but I getting error OSError: [WinError 6]

  


  Using Windows 11, Python 3.10.11
This is the method I'm trying to replicate.
(The full github is here)

  


  def clip(
        content: str, 
        video_file: str, 
        outfile: str, 
        image_file: str = '', 
        offset: int = 0, 
        duration: int = 0):
    """
    Generate the Complete Clip
    content: str - Full content text
    video_file: str - Background video
    outfile: str - Filename of output
    image_file: str - Banner to display
    offset: int - Offset starting point of background video (default: 0)
    duration: int - Limit the video (default: audio length)
    """
    audio_comp, text_comp = generate_audio_text(split_text(content))

    audio_comp_list = []
    for audio_file in track(audio_comp, description='Stitching Audio...'):
        audio_comp_list.append(AudioFileClip(audio_file))
    audio_comp_stitch = concatenate_audioclips(audio_comp_list)
    audio_comp_stitch.write_audiofile('temp_audio.mp3', fps=44100)

    audio_duration = audio_comp_stitch.duration
    if duration == 0:
        duration = audio_duration

    audio_comp_stitch.close()

    vid_clip = VideoFileClip(video_file).subclip(offset, offset + duration)
    vid_clip = vid_clip.resize((1980, 1280))
    vid_clip = vid_clip.crop(x_center=1980 / 2, y_center=1280 / 2, width=720, height=1280)

    if image_file != '':
        image_clip = ImageClip(image_file).set_duration(duration).set_position(("center", 'center')).resize(0.8) # Adjust if the Banner is too small
        vid_clip = CompositeVideoClip([vid_clip, image_clip])

    vid_clip = CompositeVideoClip([vid_clip, concatenate_videoclips(text_comp).set_position(('center', 860))])

    vid_clip = vid_clip.set_audio(AudioFileClip('temp_audio.mp3').subclip(0, duration))
    vid_clip.write_videofile(outfile, audio_codec='aac')
    vid_clip.close()


  


  My overly simplified code looks like this :

  


  clip1 = TextClip(
  txt="test",
  font="Komika",  # Change Font if not found
  fontsize=32,
  color="white",
  align="center",
  method="caption",
  size=(660, None),
  stroke_width=2,
  stroke_color="black",
)
clip2 = TextClip(
  txt="webos",
  font="Komika",  # Change Font if not found
  fontsize=32,
  color="white",
  align="center",
  method="caption",
  size=(660, None),
  stroke_width=2,
  stroke_color="black",
)
conc = concatenate_videoclips([clip1, clip2]).set_position(("center", 860))


  


  The problem is happening in the concatenate statement.

  


  The error output :

  I've tried closing the vid_clip variable and audio clips I have throughout the code but nothing seems to work.

  


  I'm trying to solve this without the need of multithreading, because I saw a couple of fixes that involved that but I don't think it is necessary in my case

  


• ffmpeg split by silence (with logic to achieve 12 split segments)

  14 mars 2023, par Martin

  https://github.com/MartinBarker/split_by_silence

  


  I am trying to automate the process of splitting a single audio file into 12 tracks. you can see in the below image that this 35:62 length mp3 file has 11 visible split points (where the audio more quiet), which means 12 distinct segments.


  


  I'd like to be able to run a script to automatically find these split points and split my file, my first split point should be around 159 seconds, and second around 360, third around 540, 4th around 780, 5th around 960, and so on for a total of 11 split points :

  


  1 159
2 360
3 540
4 780
5 960
6 1129
7 1309
8 1500
9 1680
10 1832
11 1980


  


  but my test results have not been working so good :

  


  - Goal:
11 split points found
12 tracks rendered

- Test 1
SD_PARAMS="-24dB"
MIN_FRAGMENT_DURATION="3"
5 split points found: 361.212,785.811,790.943,969.402,2150.24`
6 tracks rendered

-Test 2
SD_PARAMS="-24dB"
MIN_FRAGMENT_DURATION="3"
10 split points found: 151.422,155.026,158.526,361.212,534.254,783.667,967.253,1128.91,2150.2
11 tracks rendered


  


  

  • Test 2 Problem :
Even though 12 tracks were rendered, some split points are very close

leading to tracks being exported that are very short, such as 3, 5, and 2 seconds. as well as one long track being 16 minutes


  


  


  So I added a variable MIN_SEGMENT_LENGTH and ran another test

  


  - Test 3
SD_PARAMS="-18dB"
MIN_FRAGMENT_DURATION="3"
MIN_SEGMENT_LENGTH=120 (02:00)

log:

Exporting 12 tracks with ffmpeg...


  


  I'm unsure how to change my script and vars so that by running it, are calculating the split points, if any of them are too short (less then 120 seconds) to regenerate the split point(s) ?

  


  Here is my audio file :
https://filetransfer.io/data-package/HC7GG07k#link

  


  And here is my script, which can be ran by running ./split_by_silence.sh

• FFMPEG scaling, how to set scale so width AND height don't exceed a certain amount ?

  12 octobre 2013, par Darius

  I have 2 videos, one is 500 pixels by 100 pixels (just an example, like something recorded sideways on an iphone). And a 1980 x 400 pixels videos. I need the video to convert maintaining aspect ratios. I know of the -vf scale filter such as -vf scale=-1:320, but that only takes the width and scales the height accordingly. My 500 x 100 video would be 320px wide and 1600 pixels tall. That's bad, I need it to be max 500 pixels tall and max width of 320 (just example sizes).

  How would I configure the -vf scale function to do that ?

  Using latest ffmpeg 0.11

  Recap : scale any video to max 500 height : 320 width while keeping aspect ratio
