Moviepy: IOError: MoviePy error: failed to read the duration of file / Protocol not found

[lmsanch]

I keep getting this error, and some people have experienced this before using different versions of moviepy. As recommended, I manually istalled from Github, and I am stil lgetting the error.

I am using ubuntu 64-bit 14.04.1, Python 2.7.8 |Anaconda 2.1.0 (64-bit)| (default, Aug 21 2014, 18:22:21) [GCC 4.4.7 20120313 (Red Hat 4.4.7-1)] on linux2

This is the rest of the info:

IOError: MoviePy error: failed to read the duration of file GoPro: Alana Blanchard Surfer Girl On NetworkA.webm.
Here are the file infos returned by ffmpeg:

I have a list of webm files, and this is the only one giving me an error. It plays well, so I don't think it is a corrupted file or anything like that.

Are all the files shot with a gopro or is this the only one ?

same here - file produced with clip.write_videofile(outPath, codec='libx264')

203 seems to be about the same bug.

[Moinukhan]

Hi I am also getting same error. Please suggest me how can I overcome ?

Getting this error as well on Ubuntu 16.04. Any thoughts @Zulko?

any solutions to this problem?

[malcx95]

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

[yurastanik]

Someone solved this problem?

[Villjoie]

I solved it in a simpler way, with the help of VLC I converted the file to the forma MPEG4 xxx TV/device,
and you can now use your new file with python without any problem

xxx = 720p or
xxx = 1080p

everything depends on your choice on the output format

[tburrows13]

Feel free to reopen or start a new issue if you're experiencing this problem. However, there's probably not much that can be done to fix it without having the movie file to debug with.

[alexcdot]

I fixed this problem from a video that came from the MediaRecorder Web API (html5 web cam) by just processing it in FFmpeg like this:
ffpmeg -r <your desired frame rate> -i path/to/input_video.mp4 path/to/output_video.mp4 and then using the output video in moviepy

Feel free to reopen or start a new issue if you're experiencing this problem. However, there's probably not much that can be done to fix it without having the movie file to debug with.

Can confirm that this issue persists with webm files recorded in Chrome using the MediaRecorder API. The following results in the same error as the OP. The codec used within Chrome is Opus.

from moviepy.editor import * audio_clip = AudioFileClip('original_chrome.webm')
Here's what VLC says about the Codec:

Interestingly, if I then generate a new webm file with ffmpeg, this works perfectly well.

ffmpeg -i original_chrome.webm -ss 0 -to 5 converted_ffmpeg.webm
Attaching both files in case someone else can figure out what's happening here.

webm_samples.zip

[Heedster]

I faced the problem with .webm files recorded from the browser.
What I did was similar to what @tejpochiraju suggested, but programmatically using moviepys ffmpeg_tools:

ffmpeg_tools.ffmpeg_extract_audio(file_name, wav_file_name)

file_name is the .webm file's path, and wav_file_name is the output with .wav

Post this, AudioClip(wav_file_name) did not have the duration problem.
