Hello!
I am trying to mix an audio file and a image file and stream it to youtube.
Script with some log file output, followed by working script where I use
a playlist of video files instead
of a single image.
#!/home/per/.opam/4.05.0/bin/liquidsoap
# XTRadio Video
# Standard settings
set("log.file.path","/tmp/vlc-radio.log")
set("log.level",4)
set("server.telnet",false)
# Stream Settings
audio_file = "/tmp/bla.mp3"
video_file = "/tmp/bla.jpg"
# Create a video source with the image for video track
video = single(video_file)
audio = single(audio_file)
# Mux audio and video
#source = mux_audio(audio=audio,video)
source = mux_video(video=video,audio)
# Disable real-time processing, to process with the maximun speed
#source = clock(sync=false,source)
output.gstreamer.audio_video(fallible=true,
video_pipeline=
"videoconvert ! timeoverlay ! x264enc bitrate=2000 !
video/x-h264,profile=main ! queue ! mux.",
audio_pipeline=
"audioconvert ! voaacenc bitrate=128000 ! queue ! mux.",
pipeline=
"flvmux streamable=1 name=mux ! rtmpsink
location=\"rtmp://a.rtmp.youtube.com/live2/z69k
b187-zx59-aaw2\"",
source)
I get this in the log file:
