I tested this on the newest version, as well. Still getting the issue.
Those are the environment variables I have (that I am using for manim).
I'm having the exactly the same problem. Disrupted by the absence of some answer for this issue >:(
Try to add this file_list = "file:" + file_list
line to the file manim/manimlib/scene/scene_file_writer.py
at line number 289
just before the line movie_file_path = self.get_movie_file_path()
Didn't work
look, it says DD:/Documents...etc
but it should be D:/Documents..etc
in [concat @ 000001a1d404bf80] Impossible to open 'DD:/Documents/Coding/Installations/manim/media/videos/example_scenes/480p15/partial_movie_files/SquareToCircle/00000.mp4'
Try to add this print("file::::::", partial_movie_files)
line to the file manim/manimlib/scene/scene_file_writer.py
at line number 284
just before the line with open(file_list, 'w') as fp:
After that show your output
and check you file D:\Documents\Coding\Installations\manim\media\videos\example_scenes\480p15\partial_movie_files\SquareToCircle\partial_movie_file_list.txt
this file may also contains wrong path DD:/Documents...etc
instead of D:/Documents..etc
Followed the same tutorial and got the same error. Did try print("file::::::", partial_movie_files) line to the file manim/manimlib/scene/scene_file_writer.py at line number 284 just before the line with open(file_list, 'w') as fp: But got the same Traceback.
The path is correctly specified in the txt file
I'm facing this issue too. Impossible to open it
@NavpreetDevpuri Followed those steps, but am still getting an error. Here is what was printed:
file:::::: ['D:\\Documents\\Coding\\Installations\\manim\\media\\videos\\example_scenes\\480p15\\partial_movie_files\\SquareToCircle\\00000.mp4', 'D:\\Documents\\Coding\\Installations\\manim\\media\\videos\\example_scenes\\480p15\\partial_movie_files\\SquareToCircle\\00001.mp4', 'D:\\Documents\\Coding\\Installations\\manim\\media\\videos\\example_scenes\\480p15\\partial_movie_files\\SquareToCircle\\00002.mp4']
Also tried it with pip install manimlib
. Same error.
Also tried it with
pip install manimlib
. Same error.
This problem is with ffmpeg Try to reinstall ffmpeg
@NavpreetDevpuri Alright, I'll try.
I reinstalled it and then tested it. Works fine when I test it but I get that error still when I try to use manim.
I looked at the error some and looked again at the part that said: FileNotFoundError: [WinError 2] The system cannot find the file specified: 'D:\\Documents\\Coding\\Installations\\manim\\media\\videos\\example_scenes\\480p15\\SquareToCircle.mp4'
And, well, it definitely doesn't exist.
There is a folder within there called partial_movie_files
and in there a folder called SquareToCircle
. Inside of there, there are three mp4
files and a txt
file. The files are:
00000.mp4
00001.mp4
00002.mp4
partial_movie_file_list.txt
The .txt
file just says:
file 'D:/Documents/Coding/Installations/manim/media/videos/example_scenes/480p15/partial_movie_files/SquareToCircle/00000.mp4'
file 'D:/Documents/Coding/Installations/manim/media/videos/example_scenes/480p15/partial_movie_files/SquareToCircle/00001.mp4'
file 'D:/Documents/Coding/Installations/manim/media/videos/example_scenes/480p15/partial_movie_files/SquareToCircle/00002.mp4'
I think this had something to do with what you might have been saying above.
This is a error due to ffmpeg somehow it takes sub files names from partial_movie_file_list.txt
after that when it try to concat those videos to produce SquareToCircle.mp4
it shows error that sub files impossible to open because somehow it change the file paths from D:/Documents...etc
to DD:/Documents...etc
try to run following command in cmd
ffmpeg -y -f concat -safe 0 -i D:\Documents\Coding\Installations\manim\media\videos\example_scenes\480p15\partial_movie_files\SquareToCircle\partial_movie_file_list.txt -loglevel error -c copy D:\Documents\Coding\Installations\manim\media\videos\example_scenes\480p15\partial_movie_files\SquareToCircle\output.mp4
After that it should create a file outpu.mp4
in folder D:\Documents\Coding\Installations\manim\media\videos\example_scenes\480p15\partial_movie_files\SquareToCircle\
How, then, can we fix it? If we uninstall and reinstall but still pose the same problem.
After trying above command if it shows same error then i suggest you to post this issue about that command on stackoverflow mentioning that what your text file is containing and how it replace a single 'D' in path 'D:/Document..etc" to double 'DD' and showing error impossible to open 'DD:/Documents/....etc'
because this is a issue related to ffmpeg associate with specify system configuration
@NavpreetDevpuri I'll post a SO question like you said. I did:
ffmpeg -y -f concat -safe 0 -i D:\Documents\Coding\Installations\manim\media\videos\example_scenes\480p15\partial_movie_files\SquareToCircle\partial_movie_file_list.txt -loglevel error -c copy D:\Documents\Coding\Installations\manim\media\videos\example_scenes\480p15\partial_movie_files\SquareToCircle\output.mp4
and got:
[concat @ 0000021cf2ebbe80] Impossible to open 'DD:/Documents/Coding/Installations/manim/media/videos/example_scenes/480p15/partial_movie_files/SquareToCircle/00000.mp4'
D:\Documents\Coding\Installations\manim\media\videos\example_scenes\480p15\partial_movie_files\SquareToCircle\partial_movie_file_list.txt: Protocol not found
Did you mean file:D:\Documents\Coding\Installations\manim\media\videos\example_scenes\480p15\partial_movie_files\SquareToCircle\partial_movie_file_list.txt?
Try to change partial_movie_file_list.txt
file 'file:D:/Documents/Coding/Installations/manim/media/videos/example_scenes/480p15/partial_movie_files/SquareToCircle/00000.mp4'
file 'file:D:/Documents/Coding/Installations/manim/media/videos/example_scenes/480p15/partial_movie_files/SquareToCircle/00001.mp4'
file 'file:D:/Documents/Coding/Installations/manim/media/videos/example_scenes/480p15/partial_movie_files/SquareToCircle/00002.mp4'
After that run that command again
and try following command
ffmpeg -y -f concat -safe 0 -i file:D:\Documents\Coding\Installations\manim\media\videos\example_scenes\480p15\partial_movie_files\SquareToCircle\partial_movie_file_list.txt -loglevel error -c copy file:D:\Documents\Coding\Installations\manim\media\videos\example_scenes\480p15\partial_movie_files\SquareToCircle\output.mp4
and also try to reboot your system and run manim because sometimes ffmpeg requires rebooting
I did the second to last command and there was no error.
(after I changed the .txt
file to what you said). Should I try the last command as well?
try to run following command in cmd
ffmpeg -y -f concat -safe 0 -i D:\Documents\Coding\Installations\manim\media\videos\example_scenes\480p15\partial_movie_files\SquareToCircle\partial_movie_file_list.txt -loglevel error -c copy D:\Documents\Coding\Installations\manim\media\videos\example_scenes\480p15\partial_movie_files\SquareToCircle\output.mp4
After that it should create a file
outpu.mp4
in folderD:\Documents\Coding\Installations\manim\media\videos\example_scenes\480p15\partial_movie_files\SquareToCircle\
Is that one works fine after changes in .txt file ?
I believe so, I typed in this:
ffmpeg -y -f concat -safe 0 -i D:\Documents\Coding\Installations\manim\media\videos\example_scenes\480p15\partial_movie_files\SquareToCircle\partial_movie_file_list.txt -loglevel error -c copy D:\Documents\Coding\Installations\manim\media\videos\example_scenes\480p15\partial_movie_files\SquareToCircle\output.mp4
and got a output.mp4
file in the manim/media/videos/example_scenes/480p15/partial_movie_files/SquareToCircle
folder.
So, that is the one that worked after the changes to the .txt
file.
Now change line number 288
in file manim/manimlib/scene/scene_file_writer.py
from fp.write("file \'{}\'\n".format(pf_path))
to fp.write("file \'file:{}\'\n".format(pf_path))
after that try to run manim again
It worked! I think that it might have been on line 289, or that is from the fact that I tried your other changes before. So, is this worth me making a pull request for? Or should we I leave that for someone else that might know more about this?
Alright, thanks for all of your help. :D
I'll close the issue.
Thank you very much @NavpreetDevpuri! I added the 'file:' into line 258 and it finally work for me as well. Thank you very much :)
@NavpreetDevpuri I appreciate your help, thank you very much!
Had the same issue thanks @NavpreetDevpuri
thank you very much, it fixed my problem! @NavpreetDevpuri
There is a issue tracker now on ffmpeg: https://trac.ffmpeg.org/ticket/8674
Awesome! The pull request was merged. No one will be having this problem anymore (unless it gets fixed on ffmpeg and we then have to undo it).
I think, there will be no need to undo this because it will works fine even with file:
and there is no problem with that.
Ah, that's good.
thank you very much, it fixed my problem! @NavpreetDevpuri
@lwzzzzzzzz why are you "so upset", is everything ok? I just noticed ur status on Github.
I followed this tutorial: https://www.youtube.com/watch?v=ZltiKHFWmv8 After, I ran the
python -m manim example_scenes.py SquareToCircle -pl
command through the Windows terminal, in the manim repo folder, and got an error. Here is the trace:I am using this version of manim: https://github.com/3b1b/manim/tree/3b088b12843b7a4459fe71eba96b70edafb7aa78
