Record a live stream to disk using VLC ActiveX

Postby metalman1 » 29 Mar 2006 20:19

Is it possible to record a live stream to disk using VLC ActiveX (while the activex display the video)

This is the HTML/Javascript code to display the video (assuming the embedded object id is "vlc")
var options = new Array(":input-repeat=0");
var mrl = 'udp://@' + '224.1.1.5' + ':' + '9101';
document.vlc.addTarget(mrl, options, 4+8, -666);

Is it possible to add a "Stream output MRL" (like on the GUI) ?
And also have the activex behave as if the "Play locally" field was checked.

I've tried to look at the setVariable() without success. I guess if it's possible it would be with setVariable().

Thanks a million if you come up with the answer

I think you just need something like this, but change the output string to your specific needs, its the dst=display that makes it play on the screen too

var options = new Array(":input-repeat=0",":sout=#duplicate{dst=display,dst=std{access=file,mux=ps,url=movie.mpg}}");

Multiple comcurrent VLC instances for recording different ch

Postby mustset » 20 Apr 2007 15:16

Friends,

My objective is to record multiple channels (each from a different multicast IP/port pair) to the disk. From an external application I launch a VLC instance (vlc.exe process) for each channel. To launch VLC, I use the following command;

vlc udp:xxx.xxx.xxx.xxx:pppp --demux=dump --demuxdump-file=xxx.tmp

In most cases it works fine but in some cases (usually when I configure more than 30 channels) some of the vlc processes die just after it is created.

Do you know if there is a limit on the maximum number of concurrent instances? Or do I have to specify any other option?

Thanking in advance.

As additional information on the previously mentioned problem, below I paste some logs produced by VLC. A log file for the successfully launched instance and another log file for the crashed instance.

I would appreciate any advice.

Thanks.
