mjpeg-streamer is an easy way, but it only able to push mjpeg data, it is a waste because VoCam264 already has h264 stream inside.
So I plan to push h264 data to a RTMP server like nginx-rtmp(-module).
The first way in my mind is to use ffmpeg directly.
Just one command, and it should work: ffmpeg -re -f v4l2 -i /dev/video1 -c:v copy -f flv rtmp://192.168.0.xxx/live
My server is setup at rtmp://192.168.0.xxx/live
Note1: old version ffmpeg do not work well, I am using version 4.2.2. Currently openwrt package has ffmpeg, but it is 3.4.2, we must modify the Makefile and compile again to use latest version. I ave upload Makefile to github.com/vonger/vocore2, in utils folder.
Trying to set codec:h264 pix_fmt:none parser not found for codec h264, packets or times may be invalid.
Note2: default Makefile will show error about parser, we need to enable h264 parser.
Then ffmpeg is able to push h264 video from camera to server.
Unfortunately, the speed is very slow and video is laggy…Maybe there is something wrong, because it works well on a Linux PC..
I have to find some other way.
My compiled ffmpeg ipk download at here: http://vonger.cn/misc/vocore2/ipk/ffmpeg/
To be continue…
