RE: [Linphone-developers] question about rtp packets

[meng hongling]

another more question
Since my sound card only support stereo,I have to discard a half samples.
so I edit osscard.c oss_card_read() function like this:
char *buf;
buf=(char *)malloc(2*bsize);   ******here my board bsize=8192
err2=read(obj->fd,buf,bsize*2);
err=err2/2;
char buffer[err];
for (j=0;j<err;j=j+2)
{
buffer[j]=buf[2*j];          ******ample format is 16 bits so I have to 
discard 2 bytes in 
buffer[j+1]=buf[2*j+1];      ******every 4 bytes.
}
obj->readbuf=buffer;
.......
when I capture rtp packets with ethereal,I find it does send 50 packets per 
sencond,compared with 100 before.but I can't here clear sound but too much 
"kaka" noise at the other side of the call(with desktop computer).
Any suggestion is appreciated.
thanks a lot!
