Trying to use nginx, rtmp & ffmpeg

Added by Jason A over 3 years ago

Hello all,

I am trying to pull a stream and relay it with rtmp. I am running ffmpeg like this

/usr/local/bin/ffmpeg -loglevel fatal -f mpegts -i http://user:password@myurl:9981/stream/channelid/xxxxxxxxxx?profile=mpegts \-c:v libx264 -crf 21 -preset veryfast \-c:a aac -b:a 128k -ac 2 \-f hls -f flv rtmp://localhost:1935/hls/

Checking the tvheadend logs, I see that ffmpeg connects and is doing its job fine

tvheadend[12066]: subscription: 00DD: "HTTP" subscribing on channel "TalkingPictures TV", weight: 100, adapter: "Sony CXD2880 #0 : DVB-T #0", network: "DVB-T Network", mux: "529.833MHz", service: "TalkingPictures TV", profile="mpegts", hostname="x.x.x.x", username="streamer", client="Lavf/59.2.101"

But about 20 seconds later it disconnects

tvheadend[12066]: pass: Live stream: Write failed -- Resource temporarily unavailable
Jun 07 11:32:50 UKLDN-DP-Network tvheadend[12066]: webui: Stop streaming /stream/channelid/1xxxxxxxxx?profile=pass, muxer reported errors
Jun 07 11:32:50 UKLDN-DP-Network tvheadend[12066]: subscription: 00DE: "HTTP" unsubscribing from "TalkingPictures TV", hostname="x.x.x.x", username="streamer", client="Lavf/59.2.101"

TVHeadend is running on a Raspberry Pi 3 with the tuner HAT. I have checked the processes and it does not seem to be under any sort of stress. It's also strange that it is using a "pass" profile and not mpegts that I specifically stated in the ffmpeg command.

Has anyone had any successdoing something similar?

Thanks

Jason

Thanks for the link.

I tried to adapt the ffmpeg statement for my needs but I am still getting disconnects with the "Resource temporarily unavailable".

I am pretty sure that this does not answer your question but streaming works fine with any client...it's just ffmpeg that is causing an issue.

Run FFMpeg in terminal with more logs.
Shere you command line to test.

I have some more debug from the TVheadend side, I wonder if the epggrab is stopping the stream?

RE: Trying to use nginx, rtmp & ffmpeg - Added by Jason A over 3 years ago

If I start an ffmpeg and then a couple of seconds later try and watch a different channel in Kodi, Kodi actually works.

RE: Trying to use nginx, rtmp & ffmpeg - Added by saen acro over 3 years ago

Add user "*" with password "*"
and allow IP access from your network and 127.0.0.1
This will allow unrestricted watching (no user pass needed)

RE: Trying to use nginx, rtmp & ffmpeg - Added by Jason A over 3 years ago

I have found the issue. The TVHeadend box I am connecting to is also running a VPN Server so I can connect as a client and run FFMPEG HTTP requests through the tunnel, if I do that then there seems to be some handshaking going on and the stream works fine after it has settled down. If I connect through <myurl>:9981 (which is public) then there is no handshaking going on for some reason.

I need to think about this...
