Streaming from Raspberry cam to Mist server

[Lucas vdKroon]

Hi all,

I'm trying the MistServer's RPi image on a Raspberry B+
I was wondering if it would be possible to stream from RPi camera (via raspivid + cvlc) to MistServer via RTMP on the same board (camera-server), I've already tried with:

raspivid -o - -t 9999999 -w 1280 -h 720 --hflip | cvlc -vvv stream:///dev/stdin --sout '#rtp{sdp=rtsp://:1935/rtmp}' :demux=h264 while adding a stream to MistServer as push://127.0.0.1:1935 but it does not work.

Any ideas to point me in the right direction?

Thanks,

Lucas

Hello Lucas,

Yes, this is possible.

It looks like you're confusing RTSP and RTMP here. I'm not sure exactly how you'd use VLC to stream out over RTMP, but the following ffmpeg command should work for you:

raspivid -o - -t 9999999 -w 1280 -h 720 --hflip | ffmpeg -i - vcodec copy -f flv rtmp://localhost/live/STREAMNAME

Replace "STREAMNAME" with the name of the stream you configured, and it should work.

Additionally, in the "source" setting, do not specify a port. "push://127.0.0.1:1935" will not work, but "push://127.0.0.1" will. You can also use "push://localhost" - both values should work, but the latter also allows pushing over IPv6 instead of only IPv4. Or, if you don't care about security in this case, a simple "push://" will allow pushes from anywhere.

Hope that helped! Let me know if you run into any problems.

Helo Jaron,

Thank you for the quick reply.

I've tried what you suggested and although raspivid + ffmpeg seams to be streaming, I get the error: "Buffer has declined incoming track 2" on MistServer Controller.

Any ideas?

Thanks!

Don't mind, it's working now. While I was waiting for youre reponse, I built a MistServer instance on my VPS remotely, and I'm streaming to it from a RPi this way:

raspivid -o - -t 0 -w 1280 -h 720 --hflip | ffmpeg -i - -vcodec copy -f flv rtmp://ip.of.the.server:1935/live/rpi

I can see the stream on desktop/mobile although the stream appears as Unavailable in the Stream list?

Thanks!

Hello Lucas,

No problem! Glad to hear it's working.

By the way, the error message you saw / are seeing is just the server declining the metadata track of the RTMP stream, it's harmless.

(The open source edition only supports audio and video tracks for live streams.)

Jaron

Ok Jaron,

Thank you!

I managed to get it working on localhost too, but although it is working perfectly, stream still shows as 'unavailable' at all times. It's not that I care much about that, just wondering why!?

Thank you,
Lucas

Hello Lucas,

If I recall correctly, the RasPi build we provide is rather outdated, and this was a bug in the older version.

I'll see if we can update it to the latest release sometime soon... They are still built mostly by hand (unlike the other downloadable packages), which makes the process rather cumbersome.

Regards,

Jaron

Hello Jaron,

This time I compiled from git repo, not longer using the RPi image provided.

Thanks!
Lucas
