Using libav to create h264/mpegts stream to RTMP Server

[roxlu]

I'm working on a proof of concept where I use libav to encode raw RGB24 frames into a

H264 video and stream it using mpegts to RTMP Server. I've got the bare bones of the 

application working but it needs some more work.

Before reinventing the wheel I was wondering if others might have used a similar approach

to provide RTMP server with a video stream? I found that quite a lot of people have been 

doing/wanting to do "webcam" to "rtmpserver".

Anyone who might be interested and willing to discuss/share, please reply.

I've recently done jpeg to h264, streaming using mpegts to RTMP server. I used gstreamer (and had a ffmpeg pipeline going as well, which for some reason didnt work so well for me in terms of startup latency - but I didnt spend much time debugging). I think it should be pretty easy to adapt to an input of raw RGB24 frames.

There seem to be numerous sites on the web providing gstreamer pipelines. For example:

http://www.pieroland.net/bytes/index.php?option=com_content&view=article&id=34:gstreamer-common-commands&catid=16:various-commands&Itemid=27

ximagesrc ! videoscale ! video/x-raw-rgb,width=1280,height=720,name=capsfilter0 ! ffmpegcolorspace ! x264enc threads=2 tune=zerolatency intra-refresh=false speed-preset=ultrafast bitrate=4000 name=x264 \
mpegtsmux name=tsMux \
x264. ! tsMux. \
tsMux. ! queue ! udpblocker ! udpsink host=\"192.168.0.10\" port=3244 async=false name=udpsinker

I think you could replace all the way upto (but not including) ffmpegcolorspace and provide your inputs. Your output sink would be the port where crtmpserver is listening on udp. (I set it up in the config file as port 10000 on localhost).

Anyway, that's what I did, and it worked fine. Hope it helps in some way.

Hi bgpl, 

Thanks a lot for the info.

I'm using the libav c-library to get that working. If someone has done this before

and would like to share, please do :-)

acceptor inboundUdpTs or inboundTcpTs , then set a localstreamname to the acceptor

Can you guys help me? How did you use mpegts to send data to RTMP Server.

Do you think I should be able to get data from camcorder attached to the laptop.

How about also get from cell phone camcorder to RTMP?

thanks,

you need a codec software

you need to transform data from camera to digital data, you can try ffmpeg.

[Vishal Desai]

using digital data, can I use ffmpeg to send data to rtmp server url.

thanks,

no, read crtmpserver.lua carefully, send to the port rtmpd listening. i will go to sleep, just have a try and good luck
