[Solved] IP Cam stream and ffmpeg parameters

Hi there!

I'm trying to use as Online Source an IP Cam stream (a DLink DCS-932L).
I found the right URL for the streaming but ffmpeg is not able to identify the format.

With the -f parameter set to mjpeg, ffmpeg works.
I think I need to change the parameters passed to ffmpeg by Serviio, but under Windows environment, I haven't found any tip.

Could you help me?

Thank you all!

can you give an example of the ffmpeg command you're talking about?

Sure.
First of all: I use a Win 2008 Server environment, commands are from cmd, redirected to log file.

Command:
c:\[Serviio folder]\lib>ffmpeg.exe -i "http://[user]:[password]@[ipaddress]/video/mjpg.cgi?resolution=VGA"

What I understand is that ffmpeg is unable to detect the stream format.
In fact, if I use the -f parameter to force it, I obtain:

Command:
c:\[Serviio folder]\lib>ffmpeg.exe -f mjpeg -i "http://[user]:[password]@[ipaddress]/video/mjpg.cgi?resolution=VGA"

So, I think I need to force this parameter in Serviio call.

what if you provide the analyzeduration parameter with a high value instead?

I don't know how to increase analyzeduration, ffmpeg is a new software to me, but I can search for it.

Anyway, I think there's no need: in the meantime, good news.
Instead of trying direct connection to the ip camera, I found the video streamed by monitoring software I have installed.
Since this software lacks of DLNA capabilities, here's why I need Serviio on my W2K8 Server.

The stream is working on ffmpeg:
ffmpeg -i http://[user]:[password]@[ipaddress]:[port]/mjpg/salone/video.mjpg

Returns:

So, it seems to me that it's working, isn't it?
Furthermore, in VLC the same link is working perfectly, showing the video.

But in Serviio the Check stream URL keeps showing the red X and from two DLNA clients (Samsung TV and VLC) there is not any online content.

Some other info.

Added as Live Stream, in Serviio log file I find:
[FeedUpdaterThread] Failed to retrieve online item information for http://[user]:[password]@[ipaddress]:[port]/mjpg/salone/video.mjpg. It might not play.

Added as Web Resource I find:
Cannot parse resource from http://[user]:[password]@[ipaddress]:[port]/mjpg/salone/video.mjpg. Message: No plugin for web resource http://[user]:[password]@[ipaddress]:[port]/mjpg/salone/video.mjpg has been found.

Anyway, ffmpeg -i keeps getting information, I don't know if enough, but the url is readeble in VLC and also in Firefox.
Should I try create a plugin for this particular kind of url?

Just for information, the software from which I'm getting this mjpg stream is Blue Iris 3.

PS - sorry for my English

SOLVED.

The security software is capable of various webcasting formats.
From the point of view of ffmpeg, the difference between the working one and the others is the Metadata presence.

With MPEG-2 transport stream (MIME type video/MP2T), ffmpeg -i [streamurl] returns the Metadata too.
Green check in Serviio console and streaming (audio and video) on my TV.

Perfect!

Hope this will help others.

Hi,
After see this topic and after several days checking for other similar topics in other forums, finally I got to see the IPCamera in the TV and in XBMC by Serviio. (I can not see yet in my Philips TVs, (7007,4508, 5407, looks like the format is not supported)
I would like to write more clear how to make this, since the instrucction given here was not clearl at least for me, and made me mad several days until I found clear solution.

1. Is used the software Blu Iris 3 for to get the streaming from the IP Camera. This software has a "webcast" service that is working as a streaming service. That is simple to configurate just ussing the own instructions in the help menu. Just marking enable "JPEG,MJPEG,H.264, web/mobile streaming" in the tab webcast of camera properties.
2. in the online feeds on serviio, add a new online feed: life stream, URL: http://[URL of your server:Port]/h264/[ShortName of IPCamera from Blue Iris]/temp.ts (in my case: http://192.168.1.2:81/h264/trast/temp.ts)

I tried to write with the "ffmpeg -i" in front, but doesnt work.

By now with this is working, as I said in the XBMC by now, and following the previous in samsung TV too.
With serviigo in android device also can see, just with a delay of around 10 sec.

I find a trouble in XBMC, after open the onlinefeed is in pause, need to push play for start to see the stream and cause a little delay too, I havent idea why is happening this.

If some one need, I hope this can be clear about how to do, and sorry for my english, I try my best.
