Hi,
 
I'm trying to set channel iptv via freebox rtsp channel.
It work on my computer via VLC with rtsp port use configured on specific and unique port and configure my NAT's firewal to route the same port.
 
But on emby server, there's a issue.
In fact, I've added my .m3u playlist channel and Emby server is viewing good all channel but when I try to launch in order to see a channel, there is failed and I think that's because no port is configured and so my firewall blocked it like I've seeing this post which is about it : https://emby.media/community/index.php?/topic/34296-m3u-streaming-not-working/?hl=%2Brtsp+%2Bconfig
 
I'd search options to configure rtsp parameters on Emby server like on VLC but nothing viewed.
There are perhaps a config file which I can configure it ?
 

This is the configure .m3u added on iptv : post-161801-0-83745900-1476781599_thumb.jpg

 

This is how kodi launch "Channel" whihch is failed : post-161801-0-34660400-1476781610_thumb.jpg

 

This is how kodi viewed list channel with channel tv (exprimental) : post-161801-0-71767300-1476781611_thumb.jpg post-161801-0-80616700-1476781613_thumb.jpg

 

This is how kodi try to launch channel selected : post-161801-0-75641300-1476781612_thumb.jpg

 

And this is the log when Kodi try to launch channel selected :

Hi,

 

Thanks for helping :)

This is the last ffmpeg transcode log corresponding to the try to view channel on playlist freebox tv .m3u.

this is why I think that's my nat firewall which is blocking traffic rtsp

 

Thanks :)

Hi,

 

In order to try  understanding this problem, I watched the nat log firewall and analysed all emby server pacquet which included rtsp paquet in order to know the port or ports utilised.

 

Some example of log here :

The port request is the signing by DPT value.
After analysed this report, we can see that the emby server has send a paquet to the ip Freeplayer via the UDP protocol with some port like 32776, 32775, 32774, 32773, 32771, or 32770 and has send another pacquet to the ip Freeplayer by TCP protocol with 554 port., but I don't know what this request is.
 
 
All differents UDP requests have tried a variable port which is between 32770 and 32777 from what I see but there are perhaps a lot of other ports ?

 

I'll trying with a NAT routing port range 32770 - 32779 in order to see what's happening after that UDP request when have responsive completed status.

 

I'll come back to share my tests and what I understand after that, but I'm no very skilled on network domain.

 

Thanks & regards

Kujuta

 

 

EDIT : apparently, this ip address 212.27.38.253(freeplayer) is a IP public but rest in the LAN Network and this is this IP which is calling the real IP of the FAI video flux (hidden IP for reason copyright) which return the video flux to the source requesting.
I'm seeing a other port used, so I'll continue to try with opening this port and see what's happening...
 
EDIT2 : Ok, so I've opening the port used of the sending request of freeplayer to the real IP of the FAI channel. This is normally accepted and then, a new request is send with a new other port. Ok I'm opening this port too and then, a new request is send, and bis repetita... 
I think that rtsp protocol is using a random port and this is why VLC couldn't play anything before a patch which permit configure port used with rtsp protocol.
So, VLC can now played the channel by this way.
 
So, can you (or can I make this maybe ?) implement this parameter in order to Embyserver can run channel played ? :)

Hi,

 

I'm coming back about this problem.

After reading the ffmepg doc (https://www.ffmpeg.org/ffmpeg-protocols.html), I can see there are some parameters about rtsp ports used, especially from those arguments : (https://www.ffmpeg.org/ffmpeg-protocols.html#rtsp)

 




- min_port

Set minimum local UDP port. Default value is 5000.





- max_port

Set maximum local UDP port. Default value is 65000.


The documention precise that this options can be set on the ffmpeg command line.



Options can be set on the ffmpeg/ffplay command line, or set in code via AVOptions or in avformat_open_input

So I imagine if we add an option to configure this advanced parameters, we can set min and max on a single port or port range that will be known and therefore routable in the firewall NAT.

 

What do you think about this ?

Perhaps I haven't nothing understand & write false everything :D

 

Thanks

Kujuta

 

nb : Yet be sorry for my bad english, I don't know if I get to be understandable all the time but I try to do my best that I can :D

Hi @Luke,

Old topic but I have the same need today.

Is it possible now to specify min_port and max_port for a RTSP stream? For the moment I have forwarded UDP ports 5000 to 65000 to Emby in my firewall but that's really a very wide range, I prefer to be able to use only a few ports.

Thank you.

Hi, there is currently no option for this but it looks like something we could add.
