• Stuck in installing a voicecloner via Python (module not found)

  25 novembre 2023, par Wimmah

  I use Python 3.11.5

  


  As a great Python n00b I enter this forum because I'm stuck with installing a Voice Cloner (for personal use to do a funny trick for X-mas with my family) Its this tool that i'm trying to install : https://github.com/CorentinJ/Real-Time-Voice-Cloning

  


  With a little help of chatGTP I came quite far but for some reason the downloaded datasets cant be found. Instructions of the tool state :

  


  Install intructions form Github
So my tree looks like this :

  


  (base) willem@willems-air Voice cloner % tree
.
├── demo_cli.py
├── demo_toolbox.py
├── encoder_preprocess.py
├── encoder_train.py
├── saved_models
│   └── default
│       ├── encoder.pt
│       ├── synthesizer.pt
│       └── vocoder.pt
├── synthesizer_preprocess_audio.py
├── synthesizer_preprocess_embeds.py
├── synthesizer_train.py
└── vocoder_train.py

3 directories, 11 files


  


  However, when I give the command to execute the demo, I get the message that a needed module cant be found :

  


  (base) willem@willems-air Voice cloner % python demo_cli.py&#xA;Traceback (most recent call last):&#xA;  File "/Users/willem/Desktop/Voice cloner/demo_cli.py", line 10, in <module>&#xA;    from encoder import inference as encoder&#xA;ModuleNotFoundError: No module named &#x27;encoder&#x27;&#xA;</module>

  


  I build a tree that (for me) looks inline with the installation instructions...(And of course i downloaded the modules without any errors)
Here also the first lines of the command demo_cli.py where you also see the path :

  


  import argparse
import os
from pathlib import Path

import librosa
import numpy as np
import soundfile as sf
import torch

from encoder import inference as encoder
from encoder.params_model import model_embedding_size as speaker_embedding_size
from synthesizer.inference import Synthesizer
from utils.argutils import print_args
from utils.default_models import ensure_default_models
from vocoder import inference as vocoder


if __name__ == '__main__':
    parser = argparse.ArgumentParser(
        formatter_class=argparse.ArgumentDefaultsHelpFormatter
    )
    parser.add_argument("-e", "--enc_model_fpath", type=Path,
                        default="saved_models/default/encoder.pt",


  


  I think i missed out a quite basic step here, but this far ChatGTP is looping and cant help any more, so I need a human tip i guess ;)

  


  Thx in advance !

  


• sws/rgb2rgb : fix unaligned accesses in R-V V YUYV to I422p

  sws/rgb2rgb : fix unaligned accesses in R-V V YUYV to I422p
  In my personal opinion, we should not need to support unaligned YUY2
  
  pixel maps. They should always be aligned to at least 32 bits, and the
  
  current code assumes just 16 bits. However checkasm does test for
  
  unaligned input bitmaps. QEMU accepts it, but real hardware dose not.
  In this particular case, we can at the same time improve performance and
  
  handle unaligned inputs, so do just that.

• Stream mp4 file with watermark through a web using ffmpeg

  24 mars 2023, par Jose A. Matarán

  I'm having problems with ffmpeg, probably due to my inexperience with this software.

  


  My basic need is the following : I have a series of videos with material that I want to protect so that it is not plagiarized. For this I want to add a watermark so that when a user views it, they also see some personal data that prevents them from downloading and sharing it without permission.

  


  What I would like is to create a small Angular + Java application that does this task (invoking ffmpeg via Runtime#exec)

  


  I have seen that from ffmpeg I can emit to a server, like ffserver but I wonder if there is a somewhat simpler way. Something like launching the ffmpeg command from my java application with the necessary configuration and having ffmpeg emit the video along with the watermark through some port/protocol.

  


  EDIT

  


  I have continued to investigate and I have seen that ffmpeg allows you to broadcast for WebRTC, but you need an adapter. What I would like and I don't know if it is possible is to launch ffmpeg so that it acts as a server and it can be consumed from the web.
