Dont read rtsp stream

[flexy2dd]

Hi,

I have a small problem, Can t play the stream.
My stream provider use a simple rtsp standard

Use the netsource filter


But crash on play!

This stream run in videolan vlc

Videolan logfile

Elecard netsource logfile

Best regards

Sorry for my english

Hello flexy2dd,

Can you send me this server commands specification? Our RTSP NetSource filter does support RFC1236. I think the server you use does not stick to this RFC specification.

[KreZZoiD]

Hello flexy2dd,

one more question - does the player crash or just gives you a message that it cannot play the stream?

[unknow21]

I try to play a stream frommy freebox ( a french set top box from adsl internet provider) .

I try with directshowfilter with graphEdit.
GraphEdit crash when i supply NetSource filter to mpeg2 decoder.

Info provide by vlc:

Flux 0:
Codec: mpga
Type: Audio

Flux 1:
Codec: mpgv
Type: Video

rtsp://mafreebox.freebox.fr/freeboxtv/202

I know it's Mpeg Ts.

Can you help me?

[KreZZoiD]

Hello unknow21,

Did you use NWSource source filter or RTSP NetSource source filter?
Both  filters must be connected with MPEG2 Push Demuxer.

NWSource filter should be used if you don't plan to use RTSP commands exchange between client and server.
RTSP NetSource filer should be used if  you plan using RTSP command echange.

Hi,
I've been evaluating exactly the same thing: playing an rtsp stream from the freebox stb.

I used NWSource, Mpeg2 Push Demuxer and Elecard Decoders for audio and video, with off course the two renderer filters at the end of the graph.

I don't really get a specific error, and I can even see some frames of the video, but nothing that can be usable.

The only error I get (from time to time) is something like "trying to open a non socket object" or similar.

The log of the NWSource I get is:

One other thing.. at the end I was able to build this graph using graphedit->Open URL. Before I tried to build it myself inserting graphs by hand, but I couldn't find a way to configure the rtsp address for the NWSource filter. When I add it to the graph it asks me for a file (could that be an sdp?). If I click cancel, then using the properties editor I don't seem to be able to set the stream address.

Thanks for your help!

Hello.

1. I think that you use RTSPNetSource, because NWSource can't connect to server via RTSP. From your logs it is clear that there is no answer to PLAY request. I don't know why your server doesn't answer on it. The RTSP dialects can be diferrent on various servers. If you can send us correct commands exchange or specification we can modify RTSPNetSorce for working with this certain server.

2.

but I couldn't find a way to configure the rtsp address for the NWSource filter

You should use RTSPNetSource for it. NWSource simply receives streaming, but doesn't connect via RTSP.

Is a VLC log enough for you to underst the dialect? Or should I put some sort of proxy in the middle to dump all the network traffic?

2.

You should use RTSPNetSource for it. NWSource simply receives streaming, but doesn't connect via RTSP.

That's probably my mistake in writing, but the problem still reamins.. If I put an RTSPNetSource filter in a graph (using graphedit as example) it asks me for a file. Hitting cancel allows me to edit the properties of the filter, but I cannot find a way to set the incoming stream address in those properties.

Thanks a lot!

Yes. We need a correct log with RTSP commands: SETUP, PLAY...

Address in form "rtsp://... "should be inserted in URL field on "Settings" page.

Sorry for the delay, I was kind of busy in the last few days.

Here is the log I can get from VLC:

At a first look I don't really see the difference with the log I get using the Elecard filter. Probably it's just me not being an expert.

I hope you'll understand the problem and fix it, a lot of people is using the same STB and they would love to use different applications that VLC.

[IvanR]

Thank you for your feedback.

1. Please try to change settings in RTSPNetSource - change multicast to unicast and set your IP address as destination. (It is unicast in VLC requests)

2. It is possible that our client can't correctly work when there is different multicast address in server's answer. We will verify it and fix. But for test you can try to set 239.255.0.1 as destination in RTSPNetSource.

Hi Ivan,
do you have any news on this subject?

A lot of French users are waiting for a working version to use with this provider ;-)

Thanks a lot!

[IvanR]

Hello.

Thank you for your feedback.
We will add the support of this server in the next release of RTSPNetSource.

If you want to quicken the process, you can write to our technical support tsup@elecard.net.ru and we will discuss it.
