• Using youtube-dl and ffmpeg (or vlc) to transcode a YouTube live stream to rtsp rtmp udp rtp

  11 septembre 2018, par Matthew Wachter

  I’m trying to use youtube-dl to transcode the YouTube NASA ISS live stream (or any YouTube stream) to rtmp or rtsp. I think I have the right command but for some reason I can’t get anything to connect to my newly transcoded stream.

  Here’s the command I’m using :

  youtube-dl -f best "https://youtu.be/RtU_mdL2vBM" -o - | ffmpeg -re -f mp4 -i pipe:0 -ar 44100 -f flv rtmp://localhost:1935/test/test'

  The command appears to work and I see information about the stream files opening from YouTube but when I use the command below, vlc reports that it is unable to connect to the stream.

  vlc rtmp://localhost:1935/test/test

  ---

  If I use this next command the stream plays correctly in vlc and I can see that the youtube-dl part is functioning.

  youtube-dl -o - "https://youtu.be/RtU_mdL2vBM" | vlc -

  or simply just

  vlc -vvv https://youtu.be/RtU_mdL2vBM

  ---

  So it seems that ffmpeg is the issue or maybe I need a streaming server between the transcode and my desired destination (vlc or TouchDesigner). I’ve also tried using vlc in place of ffmpeg/youtube-dl :

  vlc -vvv https://youtu.be/RtU_mdL2vBM --sout '#transcode{vcodec=h264,vb=800,acodec=none}:rtp{sdp=rtsp://:554/test}'

  or

  youtube-dl -o - "https://youtu.be/RtU_mdL2vBM" | vlc - --sout '#transcode{vcodec=h264,vb=800,acodec=none}:rtp{sdp=rtsp://:554/test}'

  and view with

  vlc rtsp://localhost:554/test

  ---

  Unfortunately I haven’t been able make either of those methods work. I can’t even see the stream in vlc if I try to duplicate it like this :

  vlc -vvv https://youtu.be/RtU_mdL2vBM --sout '#duplicate{dst=display,dst="#transcode{vcodec=h264,vb=800,acodec=none}:rtp{,sdp=rtsp://:554/test}"}'

  Any advice would be greatly appreciated. Thanks !

  EDIT
  Here’s the ffmpeg log as requested. The program continues to run without error so I interrupted it after a about a minute.

• Is it possible to force ffmpeg to use hardware decoding with H.264 input stream ?

  27 août 2018, par Ryan Griggs

  I am running a raspberry pi 3B with ffmpeg compiled with the —enable-omx-rpi option. I am trying to do frame-capture from a webcam stream (h.264, 1920x1080) to JPG files at 5 frames per second. This operation currently causes the board to show very high CPU utilization and get very hot. For this reason, I am assuming hardware decoder is not being utilized.

  Is there a way to 1) determine whether ffmpeg is using hardware decoding, and 2) force it to be enabled ?
