  avfilter/vf_dnn_detect : fix loading anchors when labels file is set
  References https://trac.ffmpeg.org/ticket/11387
  Defining anchors is needed, even when a filename with the labels is set.
  
  The issue was identified when using yolov4-tiny model using openvino.

• Raspberry Pi cannot connect to IP camera, while Windows PC can ?

  28 novembre 2020, par gf000

  I have an IP camera (Provision ISR, DI-320IPS-VF, 2MP IR Vari-Focal Dome IP Camera). When I connect it to my router (it is a 10 or 12 years old TP-LINK TL-WR1043ND), it will immediately show up in "IP Manager" (this is a program by the manufacturer) on my Windows PC. If I double click on the camera's row, Internet Explorer opens up, and everything is working fine. On the same Windows PC, if I open VLC Media Player, and paste this URL : rtsp ://username:password@localipaddress:554/profile1
It works fine.

  


  I have also a "Raspberry Pi 4 model B 4 GB RAM", which is connected to the same router. If I open VLC Media Player, and I paste the same URL, it doesn't work. I also created an ffmpeg one-liner, which would take a photo, but that is also not working.

  


  My final goal would be to be able to take photos with that ffmpeg one-liner, on the Raspberry Pi.

  


  Maybe the Raspberry Pi is not powerful enough to handle the stream ? Or, could it be the problem that the IP-camera is sending H-264 / H-265 video stream, and the Raspberry Pi cannot handle it ?

  


  Thank you for your help. Any idea could help me.

  


• Elevenlabs API unable to find ffmpeg on device (Python 3.11)

  3 août 2023, par Ben Dyer

  When I'm trying to generate and play some speech using the elevenlabs API, the following text occurs at the very beginning of the program :
Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work
This is despite ffmpeg being installed correctly, and being recognized by Powershell. The relevent code is below.

  


  import openai, requests, ffmpeg, pydub
from elevenlabs import *

set_api_key('i have my key here')
pydub.AudioSegment.converter = 'C:/ffmpeg/bin/ffmpeg.exe'

audio = generate(
  text=(response["choices"][0]["message"]["content"]),  #<--- This is correct, and grabs the text I need.
  voice="Charlie",
  model='eleven_multilingual_v1'
  )

play(audio)


  


  I want it to simply play the audio generated through my default Windows playback device, but am instead met with the crash error upon playback ; ValueError: ffplay from ffmpeg not found, necessary to play audio.
