  spanish language file. May be we should use Salvatore, right ?

• Can't import to Unity video clip rendered using FFmpeg for Unity

  29 juin 2023, par Maximiliano Bezmalinovic

  I am using FFmpeg to render a video in Unity. For the FFmpegCaptureCommand.OutputOptions I'm using this command :

  


  -g 24 -c:v h264 -preset medium -crf 32 -pix_fmt yuv420p -color_primaries bt709 -color_trc bt709 -colorspace bt709 -color_range pc -f mov -movflags frag_keyframe+empty_moov -vf setpts=2*PTS


  


  The video output plays fine on windows media player or VLC but when I try to import the clip into Unity I get the following error :

  


  WindowsVideoMedia error 0xc00d36e6 while reading C:/.../d.mov

Context: Getting duration.
Error details: The requested attribute was not found.
Track types:
   Video Track [1024 x 1024], type: H264


  


  I can create a working copy of the video with this command :

  


  ffmpeg -i input.mov output.mov


  


  I assume ffmpeg creates a new container for the video when it copies it but I can't figure out why is not doing it in the first place.

  


  Using ffprobe

  


  ffprobe -show_streams -select_streams v C:\...\d.mov   


  


  I get this info on the original video :

  I noticed the start_time is 0.000000 on the copied video but the original is 0.066667, I wonder if that has anything to do with it.

  


  If I look at the video properties/details the "Length" attribute is missing on the original video but exists in the copy. Does Unity need that info maybe ?

  


  What am I missing here ? How could I make my original command output a video with the proper data that Unity needs for importing it ?.

  


  Thanks in advance.

  I want to make a python script to make a video in FFmpeg. I try a lot of solutions for example but I do not know Why I do not have permission to write. I have not any idea because ffmpeg errors are a little bit tricky

  


  my code :

  


  import os
import cv2

def calculate_quote_position(quote, max_length, video_width, video_height):
    if len(quote) > max_length:
        print("Quote is too long for the video.")
        return
    
    # Determine font size and alignment
    font = cv2.FONT_HERSHEY_SIMPLEX
    font_scale = 1.0
    thickness = 2
    (text_width, text_height), _ = cv2.getTextSize(quote, font, font_scale, thickness)
    
    # Calculate position for the quote
    x = int((video_width - text_width) / 2)
    y = int((video_height + text_height) / 2)
    
    return (x, y, text_width, text_height)

def create_video_from_audio_quote_picture(music_file, quote, font, font_size, font_color, background_picture, output_file, video_duration, video_width, video_height, max_length):
    quote_position = calculate_quote_position(quote, max_length, video_width, video_height)
    if not quote_position:
        print("The quote is too long for the video.")
        return
    # Create the FFmpeg command
    command = f"ffmpeg -loop 1 -t {video_duration} -i {background_picture} -i {music_file} -vf drawtext='fontfile={font}':text={quote}:fontcolor={font_color}:fontsize={font_size}:x={quote_position[0]}:y={quote_position[1]}' -shortest -c:v libx264 -c:a aac {output_file}"

    # Execute the command
    os.system(command)

music_file = "music.mp3"
quote = "This is a quote"
font = "Raleway-Bold.ttf"
font_size = 20
font_color = "white"
background_picture = "nature.png"
output_file = r"C:\Users\Lukas\Dokumenty\python_scripts\Billionare livestyle\output.mp4"
video_duration = 30
video_width = 1920
video_height = 1080
max_length = 30

create_video_from_audio_quote_picture(music_file, quote, font, font_size, font_color, background_picture, output_file, video_duration, video_width, video_height, max_length)
