[Linphone-users] Custom Splitter Filter

[Chanwit Kaewkasi]

Hi all,

I am writing a small custom MS filter that is trying to split an input to 2 outputs.

Here it is:

MSFilterDesc ms_splitter_desc={

.id=MS_SPLITTER_ID,

.name="MSSplitter",

.text=N_("Split input to 2 channels"),

.category=MS_FILTER_OTHER,

.ninputs=1,

.noutputs=2,

.process=splitter_process,

.methods=splitter_methods

};

and here's my splitter_process():

static void splitter_process(MSFilter *f){

mblk_t *refm;

while((refm=ms_queue_get(f->inputs[0]))!=NULL){

ms_queue_put(f->outputs[0],refm);

ms_queue_put(f->outputs[1],refm);

}

return;

}

But it's likely to freeze the Linphone. My question is quite simple.
- Can I put "refm" into the output queue twice?
- Or do I need to make a copy of "refm" first?

- If so, which function do I need to properly duplicate the packet and sending 2 copies of it to the different output channel?

Best regards,
