• Errno32 during MoviePy-FFMPEG write_videofile

  5 mars 2023, par Krest

  During write_videofile i get Errno32 inside Errno32

  


  def creating_video(files, title):
    fragments = []
    for file in files:
        print(file)
        clip = VideoFileClip(file).subclip()
        fragments.append(clip)
    video = moviepy.editor.concatenate_videoclips(fragments)
    video.write_videofile(f"{title}.mp4")
    return None


video_fragments = preparing_videos(title)
creating_video(video_fragments[0], video_fragments[1])


  


  files is list containing paths to mp4 files making up final video

  


  Current FFMPEG version - 5.1.2

  


  Current MoviePy version - 1.0.3

  


  I added FFMPEG to Path instead of using ImageIO-FFMPEG bundled with moviepy.
Checked different versions of FFMPEG
Checked app at linux system which generated .mp3 and mp.4 files but at the end after merging them the final file was broken.
Tried installing moviepy with pipx
On windows app doesnt even render chunks error :

  


  chunk:   0%|          | 0/11098 [00:00<?, ?it/s, now=None]Traceback (most recent call last):

BrokenPipeError: [Errno 32] Broken pipe

During handling of the above exception, another exception occurred:

OSError: [Errno 32] Broken pipe

MoviePy error: FFMPEG encountered the following error while writing file titleTEMP_MPY_wvf_snd.mp3:

• ffmpeg timelapse resets PTS on frame size change

  19 avril 2024, par Ral

  I have 601 sequential images, they change size and aspect ratio on frame 36 and 485, creating 3 distinct sizes of images in the set.

  


  I want to create a timelapse and shave off the first 200 frames and only show the remaining 401, but if I do a trim filter on the input, the filter treats each of the 3 sections of different sized frames as separate 'streams' with their own reset PTS, all of which start at the exact same time. This means the final output of the below commmand is only 249 frames long instead of 401.

  


  How can I fix this so I just get the final 401 frames ?

  


  ffmpeg \
-framerate 60 \
-i "./%07d.jpg" \
-filter_complex "
 [0]scale=1000:1000[in1];
 [in1]trim=start_frame=200[in2];
 [in2]setpts=PTS-STARTPTS
 " \
-r 60 -y trimmed.webm


  


  Filters like setpts=N/(60*TB) or setpts=PTS-SETPTS after the scale to try and fix the frame times also seem to change nothing.

  


  If I remove the trim and pts reset, the timelapse exports all 601 perfectly.
If I remove the pts reset and leave the trim, it exports 449 frames starting on frame 0.

  


  There's no errors or warning associated with the problem, other than the debug states the input reaches EOF on frame 449. (which is 485-36, the two section lengths, for some reason)

  


  I understand pre-processing the image sizes is a way to fix this, but I'd like to understand why this isn't possible in one command.

  


  version 6.0-6ubuntu1, but also happens on 6.1 and 5.1.

  


  Even if I whittle it down to the bare minimum, it still incorrectly exports 450 frames :

  


  ffmpeg -i "./%07d.jpg" -filter setpts=PTS-STARTPTS -y tpad.webm
