Trying to push RTMP stream to youtube, but youtube never display it.

[Seiken]

I'm trying to push a webcam to YouTube Live with cvlc and RTMP, but YouTube never received the data.

First, this line works fine for flv streaming. Thus it generated working video data.

Code: Select all

cvlc v4l2:///dev/video0:width=1280:height=720:chroma=h264:input-slave=alsa://hw:C920,0:v4l2-standard=1:fps=30 --sout "#standard{mux=ffmpeg{mux=flv},access=http,dst=:8080/stream.flv"

Then, I tried push RTMP to YouTube with this line, but YouTube keeps black and never received any data. Also I didn't got any warning or error message in my console.

Code: Select all

cvlc -vvv v4l2:///dev/video0:width=1280:height=720:chroma=h264:input-slave=alsa://hw:C920,0:v4l2-standard=1:fps=30 --live-caching=2500 --sout "#std{access=rtmp,mux=ffmpeg{mux=flv},dst=rtmp://a.rtmp.youtube.com/live2/xxxx-xxxx-xxxx-xxxx}"

Then, I changed few characters of the YouTube serial number in the last command, and it shows following error in my console, which make me believed that the previous command was actual pushed data to YouTube successfully but YouTube never accepted it for some reason.

Code: Select all

[rtmp @ 0x7fd6a0050800] Creating stream...

Now following is my webcam setting displayed with v4l2-ctl command.

Code: Select all

Any suggestion for how could I resolve this problem?
