Temp file not found when running GTTSExample

[azampa]

Description of bug / unexpected behavior

After installing manim-voiceover I checked installation with gtts-example.py running

manim -pql gtts-example.py --disable_caching GTTSExample

but obtained an error saying that the file GTTSExample_temp.mp4 has not been found.
The voiceovers and the video get created, but the video has no voiceover

Expected behavior

Manim should produce the video with a voiceover and should report no errors. Indeed, if I remove the manim-voiceover stuff from the python file, using a run_time of 2 seconds, all works smoothly

How to reproduce the issue

Code for reproducing the problem

See gtts-example.py distributed file

Additional comments

As you can see in the log, file GTTSExample.wav has problems: I have attached it.
It seems that the origin of the issue lies in this file...

GTTSExample.zip

[OsamaElshimy1973]

Copy all file in the Script Folder under your Manimd Enviromint Directory (....\envs..\scripts ) and past it to the same directory of your gtts-example.py and it will be resolved till they find a solution to this bug

[yvvijay121]

I also have this issue, even after trying the solution that @OsamaElshimy1973 provided. Is there any progress on this issue?

[osolmaz]

@azampa @yvvijay121 Like you said, the following lines are where the error begins:

[mp3 @ 0000022C2CC8FE00] Failed to read frame size: Could not seek to 1026.
C:\Users\ale\Python\media\videos\gtts-example\480p15\GTTSExample.wav: Invalid argument

The GTTSExample.wav you uploaded indeed does not contain any audio. That is probably a temporary file that is created before the audio is merged to the final video, since I don't see any .wav file after render is complete:

It is probably related to the logic here

https://github.com/ManimCommunity/manim/blob/cbf6726f89972580cbb64e117da56f643919857d/manim/scene/scene_file_writer.py#L626-L665

There might be something wrong with either

• your ffmpeg installation,
• or the voiceover files under /media/voiceovers

I can't replicate this locally, so can you maybe take a look at these two? You can also debug locally by inserting breakpoints with e.g. import ipdb; ipdb.set_trace() in relevant manim or manim-voiceover files.

[devRegion1]

The problem maybe due to this part in manim -> scene -> scene_file_writer.py file
self.audio_segment.export(sound_file_path, bitrate="312k")
In the above block, the 2nd parameter is not passed to "export" function call so it uses default "mp3" format to encode the output audio file with ".wav" suffix. You can try to change it as below:
self.audio_segment.export(sound_file_path, format="wav", "bitrate="312k")
It depends on your own package installation or other situations, here just for a suggestion you can try.

[melonux]

@devRegion1 Yes. I have the same problem and solved by your method. Thank you very much.

• The sound generated by GTTService is a MP3 file.
• sound_file_path = movie_file_path.with_suffix(".wav") expects a WAV file.
• self.audio_segment.export(sound_file_path, format="wav", "bitrate="312k") tries to extract sounds from the MP3 file and save to WAV file with WAV format.

I wonder if we can treat it as a bug and fix it in official package?
