IOError: MoviePy error. Failed to read duration of file

[NareshPrabhu]

I'm using RapberryPi and downloaded MoviePy. Wrote a small sample code (sample.py) below

# !/usr/bin/env python

from moviepy.editor import *
video = VideoFileClip("sampleVideo.mp4")

Is there any issue with my installation? Getting below error. ffmpeg installation was fine.

pi@raspberrypi ~/pyv $ python sample.py
/home/pi/.imageio/ffmpeg/ffmpeg.linux32: 1: /home/pi/.imageio/ffmpeg/ffmpeg.linux32: Syntax error: "(" unexpected

Traceback (most recent call last):

    filename, infos))
IOError: MoviePy error: failed to read the duration of file sampleVideo.mp4.
Here are the file infos returned by ffmpeg:

/home/pi/.imageio/ffmpeg/ffmpeg.linux32: 1: /home/pi/.imageio/ffmpeg/ffmpeg.linux32: Syntax error: "(" unexpected

Have this same issue. Referenced in #116

I got this error when trying to use MoviePy to edit video produced by the picamera library for recording from a Raspberry Pi. It produced a video in h.264 which didn't contain any duration information, which caused MoviePy and other video converters to crash. I was able to solve the problem using MP4Box to convert the video to mp4:

sudo apt-get install -y gpac
MP4Box -add video.h264 video.mp4

This created an mp4 file with the duration information so MoviePy could process it. I followed this guide: https://www.raspberrypi.org/documentation/usage/camera/raspicam/raspivid.md

This is likely long out-of-date. If the problem reoccurs, please create a new issue.

I use opencv to resave video：

def opencv_video_save_as(video_path, save_path):
    """
    video save as video
    :param video_path:
    :param save_path:
    :return:
    """
    input_movie = cv2.VideoCapture(video_path)
    width = int(input_movie.get(cv2.CAP_PROP_FRAME_WIDTH))
    height = int(input_movie.get(cv2.CAP_PROP_FRAME_HEIGHT))
    fps = input_movie.get(5)

    fourcc = cv2.VideoWriter_fourcc(*'MP4V')
    out = cv2.VideoWriter(save_path, fourcc, fps, (width, height))

    while (input_movie.isOpened()):
        ret, frame = input_movie.read()
        if (ret != True):
            break
        out.write(frame)
    out.release()
