• Python-ffmpeg video metadata editing script - Error splitting the argument list : Option not found

  16 janvier, par maric193

  I have been updating a simple script that allows me to mass edit video files metadata (in a specific folder) and save them with a new filename (inside the same folder). I have been bouncing around different forums and decided to try python-ffmpeg.
For some reason right now I am getting the below FFmpegInvalidCommand exception

  


  Error splitting the argument list: Option not found

  


  I am not quite sure what I am doing wrong here, so I am wondering if someone can give me a fresh set of eyes to determine what the problem is. Apologies in advance, there may be some leftover code that I have not cut out yet. Thanks in advance !

  


  import os
import re
import sys
from pathlib import Path
from ffmpeg import FFmpeg, FFmpegFileNotFound, FFmpegInvalidCommand
#Project looks through a folder, checks all the files in there, then edits metadata (and filename)
#and returns a new file for each file inside the folder

video = 'Anime' #Movie/TVSeries/Anime/etc...
name = 'Sword Art Online (2012)'
extension = '.mkv'
season = '01'
episode = 1

try:
    folder = r'D:\ServerTransfer\Update Server\%s\%s\S%s\\' % (video, name, season)

    #Check current file names
    print('Current names are: ')
    res = os.listdir(folder)
    print(res)
    
    # episode increase by 1 in each iteration
    # iterate all files from a directory
    for file_name in os.listdir(folder):
        # Construct old file name
        source = folder + file_name
        try:
            title = ''
            if episode < 100:
                # Adding the season & episode #'s
                destination = folder + name + '.S' + season + 'E0' + str(episode) + extension
                title = name + '.S' + season + 'E0' + str(episode)
##            elif episode < 100:
##                # Adding the season & episode #'s
##                destination = folder + name + '.S' + season + '.E0' + str(episode) + extension
            else:
                # Adding the season & episode #'s
                destination = folder + name + '.S' + season + 'E' + str(episode) + extension
                title = name + '.S' + season + 'E' + str(episode)
            # Renaming the file
            if file_name.endswith(extension):
                ffmpeg = FFmpeg(executable=r'c:\FFmpeg\bin\ffmpeg.exe').option("y").input(source).output(destination,codec="copy",title=title)
                ffmpeg.execute()
        except FFmpegFileNotFound as exception:
            print("An FFmpegFileNotFound exception has been occurred!")
            print("- Message from ffmpeg:", exception.message)
            print("- Arguments to execute ffmpeg:", exception.arguments)
        except FFmpegInvalidCommand as exception:
            print("An FFmpegInvalidCommand exception has been occurred!")
            print("- Message from ffmpeg:", exception.message)
            print("- Arguments to execute ffmpeg:", exception.arguments)
        except Exception as err:
            print(f'Unexptected {err=}, {type(err)=}')
            raise
        episode += 1
    print('All Files Renamed')
    print('New Names are')
    # verify the result
    res = os.listdir(folder)
    print(res)
except OSError as err:
    print('OS error:', err)
except Exception as err:
    print(f'Unexptected {err=}, {type(err)=}')
    raise


  


  Here is what one of my print statements in the exception says is being executed

  


  - Arguments to execute ffmpeg: ['c:\\FFmpeg\\bin\\ffmpeg.exe', '-y', '-i', 'D:\\ServerTransfer\\Update Server\\Anime\\Sword Art Online (2012)\\S01\\\\[Kosaka] Sword Art Online - 01 - The World of Swords (1080p AV1 10Bit BluRay OPUS) [73066623].mkv', '-codec', 'copy', '-title', 'Sword Art Online (2012).S01E01', 'D:\\ServerTransfer\\Update Server\\Anime\\Sword Art Online (2012)\\S01\\\\Sword Art Online (2012).S01E01.mkv']


  


  I have tried different variations of trying to run ffmpeg via python including using subprocess and shlex libraries. I also tried moviepy, however no one has answered me back on their page.

  


• JPEG image quality problems

  2 mars 2020, par atokzz

  I have two different JPEG images captured by the same source (stream IP Boroscope MJPEG). I analyzed the bytes and the structure and, with my very little experience with image byte structures, I couldn’t tell the difference between the two. So, based on the image that has no defects, what makes JPEG 2 have quality problems ?

  PS. : Both of them has the correct SOI and EOI markers (FFD8 and FFD9)

  JPEG 1 : Image without quality problems download from here to see the bytes

  Image’s preview (do not download from here)

  JPEG 2 : Image with quality problems download from here to see the bytes

  Image’s preview (do not download from here)

  Online hex editor (online hex editor to see the binary of the image)

• Cut end of multiple videos

  19 octobre 2020, par Marvin von Rappard

  I need a script to cut off the last 6 seconds of multiple videos. The videos do all have different length.

  



  I can‘t find anything helpful online.

  



  Does anyone know how to do that ?
thx
