            play(connection, message);
        })

    
        break;
    
}
})


bot.login(token);


  


  so the bot enters the voice channel but does not start the music and it give me that error.
I removed the token for privacy.

  


• OpenCV3 returning float FRAME_COUNT

  15 mars 2016, par mprat

  I am using OpenCV3 on OSX with Python 2.7 bindings. However, when I try to read the frame count of my video (a .mp4 video), it returns a float - I am expecting an int. Do I need to compile OpenCV3 with some special flags ? Am I missing some codecs ?

  import cv2
  
  vid = cv2.VideoCapture("vid.mp4")
  
  print vid.get(cv2.CAP_PROP_FRAME_WIDTH)

  And it returns a float.

  Installation details :

  • ffmpeg : brew install ffmpeg --with-dcadec --with-openh264 --with-openjpeg --with-openssl --with-tools --with-x265  --with-zimg --with-libvidstab --with-libvpx
  • opencv3 : brew install opencv3 --with-ffmpeg --with-contrib

• gst-inspect-1.0 do not see avdec_h264

  16 octobre 2020, par Marat Zakirov

  Previously I installed gstreamer via conda and its (good) plugins
next I installed gst-libav via sudo apt-get install gstreamer1.0-libav next I used apt-file list gstreamer1.0-libav to see installation path and found it to be /usr/lib/x86_64-linux-gnu/gstreamer-1.0/ next I read running gstream manual and then

  


  GST_PLUGIN_PATH=/usr/lib/x86_64-linux-gnu/gstreamer-1.0/ gst-inspect-1.0 avdec_h264

(base) marat@user-System-Product-Name:~$ ls -lh /usr/lib/x86_64-linux-gnu/gstreamer-1.0/ | grep av
-rw-r--r-- 1 root root 181K мар 21  2020 libgstavi.so

-rw-r--r-- 1 root root  72K мар 21  2020 libgstwavparse.so


  


  It found many new modules but didn't found avdec_h264. What I am missing ?

  


  UPDATE :

  


  I just want way to use gstreamer via conda virtenv python appliation. If you know valid way to do so I will consider your reply as answer.
