The VideoLAN Forums

Hello,

I am new to VLM/VLC, I'd appreciate for your pointers. In the documenation (chapter 5 - VLM), it presents an example using:

server side: client side: I am wondering how to achieve the same (VLM streaming) on HTTP protocol, so that the client may use command as .

Further, suppose I embed a media player (e.g., WMP) in HTML, and fetch video/audio from the VLM server, what should be the syntax? Is it something like:
Btw, I am using Window XP. Thanks!

you can do http streaming ... but i don't know about http VoD. (in VLC)

To stream using http you just do:

new test broadcast enabled input <input> output #std{access=http,mux=<some mux>,url=0.0.0.0:8080}
control test play

than the user will he able to listen to the streamon on http://<server ip>:8080/test

Thanks, dionoea! I appreciate your answer.

In my use case, I am more looking towards VOD over HTTP using VLM. thanks!

You can do it, you just have to specify the output before the input in your vlm configuration (for some reason when you specify an input for a VOD resource it starts immediately I think). I've done it thusly: But I'm looking into better http VOD support myself.

I too would love to see this improved. Perhaps someone knows a trick I dont. I am trying to setup vod streaming over httpd

here is a part of my vod channels.conf config file, it appears that vlc immediatly starts the first stream as soon as it gets an input..thus the load channels.conf command hangs indefinatly.
I can indeed successfully watch the first stream using vlc client by going to http://<vlc server ip>:8080/test

Any suggestions?

Two years later... I am managing with the same problem.

I have tried this:
And the telnet interface hooks with no '>' response. I have tried to receive with 'vlc http://server_ip:8080/test' and it fails. The vlm log shows that everything seems to go on its way. I am using VLC 0.8.6d for Linux and I need to stream to a WMP client.

Can anybody help, please? Much appreciated.

you can modify codes to do this.I modify httpd.c by adding "if((strstr((char *)cl->p_buffer,"DESCRIBE") ) && b_space )
{
//int j;
char * temp = strstr( (char *)cl->p_buffer, "//" ) ;
temp = temp+2;
char * temp2 = strstr(temp, "/");
temp2 = temp2+1;
// printf("(((((((((((((((=%s;=%s\n",lzj->psz_url,temp2);
// temp22 = temp2;
int ii = strlen(temp2);
char * temp3 = strstr(temp2, ".");
temp3 = temp3+1;
.................................
vlm_MediaSetup1( mediatheque, p_media, psz_cmd2 , path_name, b_last );"
do this i can achieve

did you try with:
setup test input file:///path/to/video/file/test.mpg
instead of:
setup test input /path/to/video/file/test.mpg

I have the same problem, and I also tried with your suggestion, yohann:

> setup test input file:///path/to/video/file/test.mpg

but the telnet interface just hangs after that. Streaming the video works fine though. But I cannot log in or control the vlc server anymore.

I have also tried using a config file, without success:

new test1 vod enabled
setup test1 output #std{access=http,mux=asf,url=:8080/test1}
setup test1 input /files/test1.mpg

new test2 vod enabled
setup test2 output #std{access=http,mux=asf,url=:8080/test2}
setup test2 input /files/test2.mpg

# vlc -vlm-conf vlm.conf --ttl 20 -vvv --color -I telnet --telnet-password secret
VLC starts, but does not generate the VOD streams. I have also tried using file:///files/test1.mpg instead of /files/test1.mpg

Any suggestions?

Code: Select all

you can modify codes to do this.I modify httpd.c by adding "if((strstr((char *)cl->p_buffer,"DESCRIBE") ) && b_space )

actually, DESCRIBE is a RTSP method, I don't see any link with http... but maybe this keyword is employed in HTTP streaming... I don't know.

Did you try to launch vlc with http interface and then use .../requests/vlm_cmd.xml?command=telnet_equivalent_command ?

because for me it was working fine with http commands. Maybe there is an issue with telnet interface that is not present if http request is used... ?

with:
# vlc --ttl 12 -vvv --color -I http
I can add multiple vods on the http interface, without encountering the "hanging" bug.

Input:
/var/www/movie1.avi
Output:
#std{access=http,mux=asf,url=:8080/movie1}
[x] enabled

... movie2, movie3 to :8080/movie2, :8080/movie3 ... etc.

However, they don't stream . The Server Debug sees me connect, thats all it writes:
[00000276] main http server debug: Connection from 1.2.3.4

These are the client messages:
main debug: connection in progress
access_http debug: protocol 'HTTP' answer code 404
access_http error: error: HTTP/1.0 404 Not found
access_http debug: switching to HTTP version 1.0
main debug: net: connecting to [server protected] port 8080
main debug: connection in progress
access_http debug: protocol 'HTTP' answer code 404
access_http error: error: HTTP/1.0 404 Not found


When I add the same movie with the same parameters over telnet, it streams.
>new test vod
>setup test output #std{access=http,mux=asf,url=:8080/test1}
>setup test input /var/www/movie1.avi
>setup test enabled

(I use 0.8.6d as server and client and connect to http://server:8080/movie1 in both cases)

sorry!i think you would like to realize it by rtsp

The same problem here... trying to re-stream http stream as VOD with VLM 1.0.5. Any chance this is going to be fixed? Any workaround?
I need to re-stream http stream but I need the source stream to have only one instance when many clients watching and no instance when nobody watching.

I don't think vlc can do this.
With VOD you will have one instance per client.
With broadcast you will have one instance all the time.

Do you think we can stream VOD on protocol https with VLM? Is that possible?

I am not an expert so excuse me if I am wrong. But it seems like you are trying to send the two streams over the same port.. Try change "test2"/"stream2" to port 8081 instead of 8080.

No. The problem is you cannot change the stream output protocol with VOD.
Only rtsp vod is supported.
