  dnn/vf_dnn_detect.c : add tensorflow output parse support
  Testing model is tensorflow offical model in github repo, please refer
  
  https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/tf2_detection_zoo.md
  
  to download the detect model as you need.
  
  For example, local testing was carried on with 'ssd_mobilenet_v2_coco_2018_03_29.tar.gz', and
  
  used one image of dog in
  
  https://github.com/tensorflow/models/blob/master/research/object_detection/test_images/image1.jpg
  Testing command is :
  
  ./ffmpeg -i image1.jpg -vf dnn_detect=dnn_backend=tensorflow:input=image_tensor:output=\
  
  "num_detections&detection_scores&detection_classes&detection_boxes":model=ssd_mobilenet_v2_coco.pb,\
  
  showinfo -f null -
  We will see the result similar as below :
  
  [Parsed_showinfo_1 @ 0x33e65f0]   side data - detection bounding boxes :
  
  [Parsed_showinfo_1 @ 0x33e65f0] source : ssd_mobilenet_v2_coco.pb
  
  [Parsed_showinfo_1 @ 0x33e65f0] index : 0,       region : (382, 60) -> (1005, 593), label : 18, confidence : 9834/10000.

  There are two boxes of dog with cores 94.05% & 93.45% and two boxes of person with scores 80.33% & 58.78%.

• Python - why do I get this ffprobe error ?

  4 juillet 2022, par gasper101

  I am on mac and am working on a project in which my program shoud convert a .mp3 file into a .wav file and than get text from that file (basic speech recognition). For converting a .mp3 file into a .wav file I am using ffmpeg library. I have installed both ffmpeg and ffprobe libraryies using pip and than using homebrew so I have them installed in a folder.

  


  This is my code :

  


  import speech_recognition
from pydub import AudioSegment
from os import path


#get text from original voice file------------------------------------------------- 

sound = AudioSegment.from_mp3("/path/to/file.mp3")
sound.export("/output/path/file.wav", format="wav")

file_audio = speech_recognition.AudioFile('/output/path/file.wav')

r = speech_recognition.Recognizer()
with file_audio as source:
    audio_text = r.record(source)

word = r.recognize_google(audio_text)


  


  And this is the error i get :
FileNotFoundError : [Errno 2] No such file or directory : 'ffprobe'

  


  Full error :
Warning (from warnings module) :
File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/pydub/utils.py", line 170

• ytdl python "KeyError : formats"

  7 juillet 2022, par Mondumkreisung

  Im trying to make a discord music bot for personal use, since groovy and rythm got shut down.
It's working okay-ish I guess, but im having a problem with ytdl.
typing "-play" and an url is working just like intended, but i cant type "-play 'song name'".
Typing "-play example" gives me this :

  


  [download] Downloading playlist: example
[youtube:search] query "example": Downloading page 1
[youtube:search] playlist example: Downloading 1 videos
[download] Downloading video 1 of 1
[youtube] CLXt3yh2g0s: Downloading webpage
Ignoring exception in command play:
[download] Finished downloading playlist: example
Traceback (most recent call last):
  File "C:\Users\Dennis\PycharmProjects\groovy's true successor\venv\lib\site-packages\discord\ext\commands\core.py", line 85, in wrapped
    ret = await coro(*args, **kwargs)
  File "C:\Users\Dennis\PycharmProjects\groovy's true successor\voice.py", line 53, in play
    url2 = info['formats'][0]['url']
KeyError: 'formats'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:\Users\Dennis\PycharmProjects\groovy's true successor\venv\lib\site-packages\discord\ext\commands\bot.py", line 939, in invoke

    raise CommandInvokeError(exc) from exc
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: KeyError: 'formats'


  


  im fairly new to coding, so im sorry if somethings weird to understand.

  


  okay, so : typing -play with an url works fine, but typing -play with the song name doesnt. its only searching for the first word, downloads the first searchresult and then "crashes".

  


  so "-play Rick Astley - Never Gonna Give You Up" for example only searches for "Rick" and then it says something about KeyError : 'formats'
Here is my code :

  


  @client.command()
async def play(ctx, url):
    channel = ctx.author.voice.channel
    voice = discord.utils.get(client.voice_clients, guild=ctx.guild)
    if voice and voice.is_connected():
        pass
    else:
        await channel.connect()

    ffmpeg_opts = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}
    ydl_opts = {'format': "bestaudio/best", 'default_search': 'auto'}
    vc = ctx.voice_client

    with youtube_dl.YoutubeDL(ydl_opts) as ydl:
        info = ydl.extract_info(url, download=False)
        url2 = info['formats'][0]['url']
        source = await discord.FFmpegOpusAudio.from_probe(url2, **ffmpeg_opts)
        vc.play(source)
