Purpose:
live streaming the video capture card to Browser.
Approaches tried:
- -Wowza + ffmepg
wowza 4.0, config... ffmepg:
avconv -re -f video4linux2 -i /dev/video0 -b:v 300k -c:v libx264 -g 15 -pix_fmt yuv420p -an -f flv rtmp://171.71.46.197:1935/live/myStream
working, but it has 5 seconds delay.
- -VLC streaming
not success
- -MEPG-DASH
not success. gpac reports error while streaming. lacks of codec. Maybe it's working well with webcam. but it has problem with capture card.
- -WebRTC
not sucess. Screen is black.
- -FFMPEG webm encoding + HTTP + video TAG.
It's pretty good to have video tag. workable. 3 seconds delay.
- -jsmpeg+ws+ffmepg
- ffmpeg:
avconv -s 640x480 -f video4linux2 -i /dev/video0 -f mpeg1video -b 800k -r 30 http://127.0.0.1:8082/herry/640/480/
- server node.js:
accept the mpeg1 data and send it out to client.
- client side:
using jsmpeg to decode the data from websocket. It's basiclly no delay. less than 1s
- -broadway (h264 livestreaming)
working well now.
