• Using FFMPEG to stream my WebCam's video to YouTube

  12 mars 2017, par Indes

  I’ve been trying to use ffmpeg to stream my webcam’s video to YouTube and so far all I’ve managed was an "acknowledgement" from YouTube saying ’Starting’ in green. However it quickly goes gray and the actual stream never actually changes from offline.

  I’m using this command to try to stream it :

  ffmpeg -rtbufsize 1500M -r 25 -f dshow -s 1280x720 -i video="USB2.0 HD UVC WebCam" -vcodec h264 -b:a 600k -acodec libfaac -ab 128k -f flv "rtmp://a.rtmp.youtube.com/live2/user.useruser.codecodecode"

  CMD

  I’ve managed to stream videos to YouTube with ffmpeg, its just the camera that won’t work. Any idea what I might be doing wrong ?

  This is the command I’m using now
  ffmpeg -r 18 -f dshow -s 1280x720 -i video="USB2.0 HD UVC WebCam":audio="Microphone (Realtek High Definition Audio)" -vcodec h264 -b:v 1800k -acodec aac -strict experimental -f flv "rtmp://a.rtmp.youtube.com/live2/useruser.useruser.codecodecodecode"

  I’m now using -acodec aac instead of libfaac or libfdk_aac since I was getting "Unknown encoder" errors

  It is streaming a few seconds however, now I’m getting these errors :
  WriteN, RTMP send error 10053

  Any idea what these mean, or how to fix them ?

• How to Live Stream YouTube without Audio [on hold]

  23 septembre 2016, par arsenalist

  I have two IP cam and a computer with ffmpeg to re-stream them to YouTube.

  First Cam

  It has Video and Audio. I can re-stream to YouTube successfully with this command.

  ffmpeg -re -rtsp_transport tcp -i rtsp://192.168.aaa.bbb:554/ch0_1.h264 -acodec libmp3lame -ar 44100 -b:a 128k -pix_fmt yuv420p -profile:v baseline -s 426x240 -bufsize 2048k -vb 400k -maxrate 800k -deinterlace -vcodec libx264 -preset medium -g 30 -r 30 -f flv rtmp://a.rtmp.youtube.com/live2/

  Second Cam

  It has Video only. However, with both commands below, I can’t stream to YouTube. (although the ffmpeg process is running well)

  ffmpeg -re -rtsp_transport tcp -i rtsp://192.168.aaa.ccc/Streaming/Channels/102 -an -pix_fmt yuv420p -profile:v baseline -s 426x240 -bufsize 2048k -vb 400k -maxrate 800k -deinterlace -vcodec libx264 -preset medium -g 30 -r 30 -f flv rtmp://a.rtmp.youtube.com/live2/

  or

  ffmpeg -re -rtsp_transport tcp -i rtsp://192.168.aaa.ccc/Streaming/Channels/102 -acodec libmp3lame -ar 44100 -b:a 128k -pix_fmt yuv420p -profile:v baseline -s 426x240 -bufsize 2048k -vb 400k -maxrate 800k -deinterlace -vcodec libx264 -preset medium -g 30 -r 30 -f flv rtmp://a.rtmp.youtube.com/live2/

  I’ve test both camera’s stream first using FLV, and they work well. So, the issue is not the URL of IP camera.

  From what I understand, YouTube define stream as audio-video content. However, what if the source only has Video.

  So, my question :

  How to live stream YouTube without audio, specially from an IP cam ?

  Thanks

• The Ultimate YouTube-DL script [on hold]

  30 juillet 2018, par G. L.

  I need help creating/finishing a bash script. What I’m trying to do is to create the perfect YouTube-DL archiving script.
  As of now, the only thing I can do is download all of a Users’ videos, embed subtitles, add metadata but I want to also autosub the files (with script number 2) and convert the downloaded files with ffmpeg or AVConv or handbrake-cli and then remove the video files when I have a successful conversion.

  Script 1 (downloads videos skipping already downloaded ones)

  youtube-dl -i -o "%(title)s-%(id)s.%(ext)s" --all-subs --embed-subs --embed-thumbnail --add-metadata --sleep-interval=20 --rate-limit=1M --exec 'youtube-dl2kodi.py -t tvshow -f {}' --download-archive .archive $(cat url.txt) 

  Note : youtube-dl2kodi.py creates Kodi compatible nfo files so I can view them properly on Kodi with metadata.

  Script 2 (subtitles videos automatically using autosub)

  for file in *I WANT TO AUTOSUB files in this directory and subdirectories*
  
  do
  
    autosub -S de -D de "$file" >> results.out
  
  done

  I want to merge script 1 and 2 and then encode the files and remove original video files (mp4, mkv and webm) if successful.
  My encoding preference is HEVC with CRF 23 and I don’t want to encode the audio. I want to copy the audio. The final video would be a MKV file.
