Problem saving stream (RTMP)

Posted: 09 Nov 2009 18:44
by beavaman
hi there,

when i want to open and convert a videostream (RTMP), VLC 1.0.3 (latest version) quits the conversion process within a few minutes, so i end up with a partly downloaded (and converted) file.

what i select:
1) Media --> Convert/Save --> Network
2) Protocol: RTMP
3) Address: rtmp://edge02.fms.dutchview.nl:1935/hetgesprek/20080516160000AMS_2_1_1311
4) click Convert/Save
5) Destination file: C:\directory\filename.asf
6) Profile: Video - WMV + WMA (ASF)
7) check Dump raw input

i tried different output settings besides ASF and WMV, and also the "Stream Output way" (which has slightly different output options), but it abruptly ends everytime. any ideas how i can capture this video? i'd like to have the file as lossless/uncompressed as possible.

link to watch video online: http://www.hetgesprek.nl/archief/1105/
link to paste in VLC (URL): rtmp://edge02.fms.dutchview.nl:1935/hetgesprek/20080516160000AMS_2_1_1311

What if you just play the url and use the record button?

Hi beavaman,

I don't have the answer, but would like to ask you something.

I was wondering how did you find out the RMTP url as rtmp://edge02.fms.dutchview.nl:1935/hetgesprek/20080516160000AMS_2_1_1311 ? I tried a couple of times, but couldn't figure that out. Please let me know.

Thank you,

DL

You can use Wireshark to sniff out URLs.

to view the stream url you can also right-click on the page the video gets played and "view page source" (if you use firefox) and find the link to the stream.

Thanks all for the tips of sniffing URLs by Wireshark and viewing source codes (html/xml/action script). But it doesn't work in my case.

I wanted to use VLC to play (and save) a live TV in this website (http://xemtivi.net). I found that the url is referred by a XML file. I extracted the XML file and found the rtmp URL. Then, I tried to play VLC with such rtmp URL, but it didn't show anything. The log of VLC said that the connection hasn't been made, and it seems like I got a wrong URL? Or may be VLC does not support a live RTMP?

Please let me know.

Thanks,

XML file: http://vtc.com.vn/XMLFile.aspx?id=3&tp=l
RTMP url: rtmp://118.143.234.130/live/vtv32

Then the server rejects the connection for some reason.

Then the server rejects the connection for some reason.
Is there a way we can see how and why the connection has been rejected? Since I tried to use another app to capture/download rtmp flash and it works fine with the website and the rtmp url, so I suspect whether or not the connection issue belongs to VLC. Please correct me if I'm wrong.

I am guessing the URL isn't enough but some additional data should be send to server.

I think it's hard to tell how the connection is rejected by using Wireshark to sniff its traffic, since it seems the transmitted data is encrypted.

I downloaded and decompiled the server side player and can see its code (Action Script). I don't know if that helps since I don't have knowledge of the AS. But take a look if you have a chance, and hope you may find something. If so, please let me know.

I haven't studied it either.

Hi, I have a slightly related question, hence post it here instead of open another topic.

Suppose everything goes well, is the stream content temporally cached and stored as a file before it's streamed or it's just buffered in memory?

Thanks,

VLC doesn't cache to HD if that is what you asked.
