• 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 !

• How to config FFmpeg for xrgb and Aver Media capture card [closed]

  12 mai 2023, par Plotter Desalor

  I'm trying to use FFmpeg through ffplay to display a capture card output as lossless as possible.

  


  My capture card is named "Live Gamer Ultra-Video"

  


  In OBS, the NV12, YV12, P010 and YUY2 lead to blurriness around text and fine pixels edges, but the XRGB one offer clear output. So I've tried to focus on this mode with FFmpeg as the default one lead to same blurriness seen in OBS.

  


  Running "ffmpeg -f dshow -list_options true -i video="Live Gamer Ultra-Video" show me this result
(i've only kept line with wanted resolution)

video=Live Gamer Ultra-Video: Immediate exit requested


  


  "unknown compression type 0xE436EB7D" is a pretty bad start but from https://trac.ffmpeg.org/ticket/6279 I could figured out it was just unproperly parsed RGB24 format

  


  But if I run a very simple "ffplay -f dshow -i video="Live Gamer Ultra-Video" -pixel_format rgb24"
I got this output

  How could I use rgb format with this capture card ?

  


  If not possible, any other format leading to proper output would be ok too.
I've tried parameters from this topic Capture full-range/lossless rgb frame from capture card that supports NV12 and YUYV output without any good result sadly.
