• Is it possible to seek through streamed youtube audio with discord.py (play from a given timestamp in the video) ?

  13 juin 2020, par apc518

  Unfortunately passing in a URL with a &t= tag does not cause discord.py's VoiceClient to start playing at that timestamp. I'm using youtube_dl.

  



  Is is possible to seek through audio within discord.py in order to start streaming a YouTube video from somewhere besides the start ?

  



  I know some professional bots like Groovy have seek commands for streamed YouTube videos, so the Discord API itself is capable of this.

  



  The code I'm using is from here.

  


• Two rtsp streams to youtube on a Pi3

  19 mars 2020, par Sébastien Bonaimé

  I want to stream two rtsp camera from my birdbox to youtube from my raspberry pi 3 with the entrance in Pip (picture in picture) on top left. I don’t need sound.

  192.168.1.13 can do 30 fps with sound that I don’t need
  192.168.1.31 is only 12 fps without sound

  I have some problems of lag between the two camera on the youtube stream which I think is due to the different fps. I compile ffmpeg with h264. Here is what I did

  ffmpeg -re -f lavfi -i anullsrc -rtsp_transport udp -thread_queue_size 1000k -i rtsp://admin:123@192.168.1.13:554 -i rtsp://admin:@192.168.1.31:554 -filter_complex "[1]scale=iw/4:ih/4[pip]; [2][pip] overlay=0:0"   -framerate 13  -bufsize 512k  -b:v 1500k -threads 4 -q:v 3  -c:v h264_omx  -c:a aac -f flv rtmp://a.rtmp.youtube.com/live2/XXX-XXXX-XXX

  and here are the errors

  [h264 @ 0x20ddd30] error while decoding MB 69 67, bytestream -6rate=1589.2kbits/s dup=0 drop=6 speed=0.997x

  [rtsp @ 0x1f2cea0] max delay reached. need to consume packetbitrate=1588.9

  What can I do to improve the stream ? When a bird enter the box, there is also a quality problem when the image is changing and some lagging.

• streaming on youtube with ffmpeg [on hold]

  20 septembre 2017, par Bojan Dedić

  I found this code on internet and it works great for streaming live videos on youtube. Only problem is that I need to stream every video which is inside folder "videos", not only just one.

  VBR="2500k"                          
  
  sortie
  
  FPS="30"               
  
  QUAL="medium"                                  
  
  YOUTUBE_URL="rtmp://a.rtmp.youtube.com/live2"  
  
  
  
  SOURCE="video.mp4"    
  
  KEY="..." 
  
  
  
  ffmpeg \
  
     -i "$SOURCE" -deinterlace \
  
     -vcodec libx264 -pix_fmt yuv420p -preset $QUAL -r $FPS -g $(($FPS * 2)) -b:v $VBR \
  
     -acodec libmp3lame -ar 44100 -threads 6 -qscale 3 -b:a 712000 -bufsize 512k \
  
     -f flv "$YOUTUBE_URL/$KEY"

  This is what i came up with :

  for f in *.mp4; do
  
      ffmpeg \
  
          -i "$f" -deinterlace \
  
          -vcodec libx264 -pix_fmt yuv420p -preset $QUAL -r $FPS -g $(($FPS * 2)) -b:v $VBR \
  
          -acodec libmp3lame -ar 44100 -threads 6 -qscale 3 -b:a 712000 -bufsize 512k \
  
          -f flv "$YOUTUBE_URL/$KEY"
  
  done
