[FFmpeg-user] FFMpeg/FFServer P2P streaming between ubuntu based embedded device and smartphone

[Bogdan Mariesan]

Hi,

I've been playing for the last couple of days with FFMpeg and FFServer as
are considering as a candidate for livestreaming between an embedded
device(with an integrated HD camera) and various clients(smartphones).

I've managed to achieve this using with the following config for FFServer:

HTTPPort 1234
> RTSPPort 1235
> MaxHTTPConnections 2000
> MaxClients 1000
> MaxBandwidth 512000             # Maximum bandwidth per client
>                                # set this high enough to exceed stream
> bitrate
> CustomLog -
> NoDaemon                       # Remove this if you want FFserver to
> daemonize after start
> <Feed feed.ffm>               # This is the input feed where FFmpeg will
> send
>   File /tmp/feed.ffm            # video stream.
>   FileMaxSize 512K
> </Feed>
> <Stream test.h264>                      # Output stream URL definition
>    Feed feed.ffm              # Feed from which to receive video
>    Format rtp
>    # Video settings
>    VideoCodec libvpx
>    VideoSize 720x576           # Video resolution
>    VideoFrameRate 60           # Video FPS
>    AVOptionVideo flags +global_header  # Parameters passed to encoder
>                                        # (same as ffmpeg command-line
> parameters)
>    AVOptionVideo cpu-used 0
>    AVOptionVideo qmin 10
>    AVOptionVideo qmax 42
>    AVOptionVideo quality good
>    AVOptionAudio flags +global_header
>    PreRoll 15
>    StartSendOnKey
>    VideoBitRate 400            # Video bitrate
>    NoAudio
> </Stream>


And the following FFMpeg command to send the stream to FFServer:

ffmpeg -rtbufsize 2100M -f dshow -i video="Integrated Camera" -vcodec
> libx264 http://127.0.0.1:1234/feed.ffm <http://127.0.0.1:1234/feed1.ffm>


I also have a simple Android client that plays the RTSP stream using the
following URL:

rtsp://mylocalnetworkip:1235/test.h264


What I am trying to achieve is a direct P2P connection between the embedded
device and a smartphone. This has to be over the internet and capable to
achieve UDP punch holes (such as Skype does for p2p video-calling).

Is this achievable with ffmpeg? If yes can you please provide some guidance
in how to achieve a P2P stream over the internet?

Kind regards,
