I use the python imageio package to convert a .mp4 video to a .avi video, keeping the fps and size same. The following is my code: import imageio src_dir = "my/source/video.mp4" dst_dir = "my/dst/video.avi" reader = imageio.get_reader (src_dir) fps = reader.get_meta_data () ['fps'] writer = imageio.get_writer (dst_dir, fps=fps) for im in reader Today we will learn how to convert videos to MP3 files using ffmpeg in Python. 📚 Programming Books & Merch 📚🐍 The Python Bible Book: https Use moviepy to convert MP4 to MP3. There are many programs and packages for converting videos into audio files. Here I chose moviepy directly because the code is very short. First of all, we still have to download moviepy. sudo pip3 install moviepy. After the download is complete, let’s convert the downloaded file into test.mp3. However, ffmpeg-python seems to work well for both simple and complex usage. Below is the code responsible for extracting the metadata: import ffmpeg import sys from pprint import pprint # for printing Python dictionaries in a human-readable way # read the audio/video file from the command line arguments media_file = sys.argv[1] # uses ffprobe import moviepy import os import moviepy.editor import tempfile pathdir = "path/to/dir" for filename in os.listdir (pathdir): filename.endswith (".mkv") print (filename) video = moviepy.editor.VideoFileClip (filename) audio = video.audio audio.write_audiofile (filename + ".wav") else: print ("Finished conversion") And this is what comes up I want to load an audio file of any type (mp3, m4a, flac, etc) and write it to an output stream. I tried using pydub, but it loads the entire file at once which takes forever and runs out of memory easily. I also tried using python-vlc, but it's been unreliable and too much of a black box. Convert a Video to MP4 Using python-opencv ¶. The code below converts a MOV vidoe file to a MP4 vidoe file using OpenCV in Python. The above code might fail to work if your OpenCV is compiled with H264 encoding support. In that case, you can use MPV4 or AVC1 instead. Here is how you can import the video file inside the python code: video = mp.VideoFileClip(r"sample.mp4") #here sample.mp4 is the name of video clip. 'r' indicates that we are reading a file. Now it's time to convert the video file into audio file. We will be converting the .mp4 file into .mp3 file. To do this add the following line in the program: How to extract audio from video file. How to convert video into audio. MoviePy: pip install moviepy----- So I was hopping there was any way to use a Python lib to convert. But yeah, ftransc seems to work, and I can try to fit it in. Thanks! 1. Oxbowerce. • 3 yr. ago. You could also use the pydub library to load the audio using AudioSegment.from_ogg and then save it again as an mp3. t-freitaz. 2IHdd.
