Adding video in ppt using python cannot be played

Adding video in PowerPoint presentations using Python can sometimes result in videos that cannot be played. This can be due to various reasons such as incompatible video formats or missing codecs. In this article, we will explore three different solutions to this problem.

Solution 1: Converting the Video Format

One possible solution is to convert the video to a compatible format that PowerPoint supports. Python provides several libraries that can be used to convert video formats, such as moviepy or ffmpeg-python.


import moviepy.editor as mp

def convert_video(input_file, output_file):
    video = mp.VideoFileClip(input_file)
    video.write_videofile(output_file)
    
input_file = "video.mp4"
output_file = "converted_video.avi"
convert_video(input_file, output_file)

This code snippet demonstrates how to use the moviepy library to convert a video file from one format to another. You can specify the input file and the desired output file format. Once the conversion is complete, try adding the converted video to your PowerPoint presentation and see if it can be played.

Solution 2: Installing Missing Codecs

If the issue is related to missing codecs, you can try installing the necessary codecs on your system. Python provides the pydub library, which can be used to install missing codecs.


import pydub

pydub.get_codec('mp4')

This code snippet checks if the required codec for the MP4 format is installed. If it is not installed, you can use the following command to install it:


pydub.get_codec('mp4').install()

After installing the missing codec, try adding the video to your PowerPoint presentation again and see if it can be played.

Solution 3: Embedding Video as an Object

If the above solutions do not work, you can try embedding the video as an object in your PowerPoint presentation. This can be done using the python-pptx library.


from pptx import Presentation

def add_video_slide(presentation, video_file):
    slide_layout = presentation.slide_layouts[1]
    slide = presentation.slides.add_slide(slide_layout)
    content_slide = slide.shapes.add_movie(video_file, left=0, top=0, width=914400, height=685800)
    
presentation = Presentation()
video_file = "video.mp4"
add_video_slide(presentation, video_file)
presentation.save("presentation.pptx")

This code snippet demonstrates how to add a video slide to a PowerPoint presentation using the python-pptx library. You can specify the video file and customize the position and size of the video on the slide. Save the presentation and check if the video can be played.

After trying out these three solutions, it is difficult to determine which one is better as it depends on the specific requirements and constraints of your project. Solution 1 provides a general approach to converting video formats, while Solution 2 focuses on installing missing codecs. Solution 3 offers a different approach by embedding the video as an object. Consider the specific needs of your project and choose the solution that best fits your requirements.
