• Error in writing video file using moviepy and ffmpeg

  13 juillet, par Divakar Sharma

  I have been working with moviepy library for the first time. I have a video clip around 7 hours long, and I'd like to clip it into small clips. I have a list of start and end time.

  


  video = VideoFileClip("videoFile.mp4")
clips = []
for cut in cuts:
   clip = video.subclip(cut[0], cut[1])
   clips.append(clip)
clips
clip = video.subclip("7:32:18", "7:38:38")
clips.append(clip)
for clip, title in zip(clips, title_list):
 clip.write_videofile(title + '.mp4', threads=8, fps=24, audio=True, codec='libx264',preset=compression)
video.close()


  


  clips[] contain the start and end time for clipping. I have a list of title too which I have scraped from youtube. I have not included the two lists here but a small example could be :

  


  cuts = [('0:00', '2:26'),
 ('2:26', '5:00'),
 ('5:00', '7:15'),
 ('7:15', '10:57'),
 ('10:57', '18:00'),
 ('18:00', '18:22'),
 ('18:22', '19:57'),
 ('19:57', '20:37'),
 ('20:37', '28:27'),
 ('28:27', '40:32'),
 ('40:32', '49:57'),...
title_list = ['Introduction (What is Todoist?), tech stack talk', 'Showing the final application (with dark mode!)', 'Installing create react app', "Clearing out what we don't need from create react app", "Let's get building our components!", 'Installing packages using Yarn', 'Building the Header component', 'Building the Content component',...


  


  OSError: [Errno 32] Broken pipe

MoviePy error: FFMPEG encountered the following error while writing file Introduction(WhatisTodoist?),techstacktalkTEMP_MPY_wvf_snd.mp3:

b'Introduction(WhatisTodoist?),techstacktalkTEMP_MPY_wvf_snd.mp3: Invalid argument\r\n'

In case it helps, make sure you are using a recent version of FFMPEG (the versions in the Ubuntu/Debian repos are deprecated).


  


  Above is the error I am getting after running the write_videofile(). I have looked at the documentation and the issues on github, I tried updating the ffmpeg through pip too. I don't know why it can't write the audio file.

  


• Broken pipe when writing video file with moviepy in azure [closed]

  5 juin 2024, par Lydia

  I have a program that retrieves images (png) and audio files from Azure Blob Storage to merge them into a video, which is then written to a temporary file and saved back to Blob Storage. I'm coding in **Python **and here is the function I use from MoviePy :
final_clip.write_videofile(temp_file_name, fps=24, codec='libx264', audio_codec='mp3')
I have containerized my code, and the **Docker **image works perfectly on my machine. However, once deployed on Azure, I encounter this problem with writing the video :

  


  Failed: [Errno 32] Broken pipe MoviePy error: FFMPEG encountered the following error while writing file /tmp/tmp81o22bka.mp4: b'' Traceback (most recent call last): File "/usr/local/lib/python3.8/site-packages/moviepy/video/io/ffmpeg_writer.py", line 136, in write_frame self.proc.stdin.write(img_array.tobytes()) BrokenPipeError: [Errno 32] Broken pipe During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/home/site/wwwroot/function_app.py", line 102, in generate_simple_video image_clip.write_videofile(temp_file_name, fps=24) File "", line 2, in write_videofile File "/usr/local/lib/python3.8/site-packages/moviepy/decorators.py", line 54, in requires_duration return f(clip, *a, **k) File "", line 2, in write_videofile File "/usr/local/lib/python3.8/site-packages/moviepy/decorators.py", line 135, in use_clip_fps_by_default return f(clip, *new_a, **new_kw) File "", line 2, in write_videofile File "/usr/local/lib/python3.8/site-packages/moviepy/decorators.py", line 22, in convert_masks_to_RGB return f(clip, *a, **k) File "/usr/local/lib/python3.8/site-packages/moviepy/video/VideoClip.py", line 300, in write_videofile ffmpeg_write_video(self, filename, fps, codec, File "/usr/local/lib/python3.8/site-packages/moviepy/video/io/ffmpeg_writer.py", line 228, in ffmpeg_write_video writer.write_frame(frame) File "/usr/local/lib/python3.8/site-packages/moviepy/video/io/ffmpeg_writer.py", line 180, in write_frame raise IOError(error) OSError: [Errno 32] Broken pipe MoviePy error: FFMPEG encountered the following error while writing file /tmp/tmp81o22bka.mp4: b''


  


  From my online research, everyone suggests that it’s a resource issue (lack of RAM and CPU). I increased these resources in the Azure Function App configuration, but I still face the same problem.

  


  I took a step-by-step approach to check for compatibility issues with the MoviePy function. I created a small 30-second video without audio, and it worked. Then, I added more options such as more images, audio, etc., but it failed.

  


  I suspected a timeout issue, but even with an execution time of one minute only, it still fails.

  


  I am out of ideas to test and really need help.

  


  Thank you in advance.
