Some question about code in speex_jitter_buffer.c #12
Description
I can not understand why we make speex_decode_int of jitter->current_packet 2 times
first time after get packet from buffer, after set flag valid_bits to 1, second time at next speex_jitter_get call
void speex_jitter_get(SpeexJitter *jitter, spx_int16_t *out, int *current_timestamp) {
//....
if (jitter->valid_bits)
{
//
// here we decode last received packet to out second time
//
ret = speex_decode_int(jitter->dec, &jitter->current_packet, out);
//...
}
//....
//
// here we decode last received packet to out first time
//
ret = speex_decode_int(jitter->dec, &jitter->current_packet, out);
if (ret == 0)
{
jitter->valid_bits = 1;
}
//....
}Thanks!
