Purpose:

live streaming the video capture card to Browser.

Approaches tried:

1. -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.

2. -VLC streaming

not success

3. -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.

4. -WebRTC

not sucess. Screen is black.

5. -FFMPEG webm encoding + HTTP + video TAG.

It's pretty good to have video tag. workable. 3 seconds delay.

6. -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

7. -broadway (h264 livestreaming)

working well now.

8. others

test-mjpeg.js is used to generate jpg files from video. ff.conf is the configration file for ffserver. Not success.
