stream static file

[Carl Karsten]

I am experimenting with youtube live sreams.    I created an account, put
the secret in auth.sh, and this works:


gst-launch-1.0 \
        videotestsrc pattern=18 is-live=1 \
        ! video/x-raw, framerate=30/1, width=426, height=240 \
        ! timeoverlay \
        ! x264enc bitrate=2000 key-int-max=60 bframes=0 byte-stream=false
aud=true tune=zerolatency \
        ! h264parse \
        ! "video/x-h264,profile=main" \
        ! queue \
        ! mux. audiotestsrc is-live=true \
        ! "audio/x-raw, format=(string)S16LE, endianness=(int)1234,
signed=(boolean)true, width=(int)16, depth=(int)16, rate=(int)44100,
channels=(int)2" \
        ! voaacenc bitrate=128000 \
        ! flvmux streamable=true name=mux \
        ! rtmpsink location="rtmp://a.rtmp.youtube.com/live2/x/$AUTH
app=live2"

maybe you can see it here:

Now I would like to swap the ball/tone with content from a file.  the file
I am using is an mp4 that my be the same encoding as I need to send, but I
would like to demux, timeoverlay, encode, send.

I am assuming I need is-live=1 somewhere.  And I need to keep sync.

I took a shot and realized I am in over my head, but here it is, maybe I am
close, or maybe it will make someone laugh:

uri=file:///home/carl/Videos/What_teachers_really_need_from_us.mp4

gst-launch-1.0 \
    uridecodebin uri=$uri \
        ! tsdemux \
        ! timeoverlay \
        ! x264enc bitrate=2000 key-int-max=60 bframes=0 byte-stream=false
aud=true tune=zerolatency \
        ! h264parse \
        ! "video/x-h264,profile=main" \
        ! queue \
        ! mux. "audio/x-raw, format=(string)S16LE, endianness=(int)1234,
signed=(boolean)true, width=(int)16, depth=(int)16, rate=(int)44100,
channels=(int)2" \
        ! voaacenc bitrate=128000 \
        ! flvmux streamable=true name=mux \
        ! rtmpsink location="rtmp://a.rtmp.youtube.com/live2/x/$AUTH
app=live2"


(gst-launch-1.0:27423): GStreamer-CRITICAL **: gst_element_make_from_uri:
