Hello, After checking out CVS HEAD from yesterday (for those new PLC/Jitterbuffer patches), I was affected by bug 3795 with my Polycom IP600's. After seing it resolved as of this morning (thanks Mark), I decided to try again... I can answer incoming calls. No problem there. Putting calls on hold, however, results in my Polycom IP600 indicating the call on hold, but the caller does

I've just setup a new asterisk box (cvs HEAD) with a digium tdm411 and a couple computers with eyebeam. I have one small. I cannot call the eyebeam clients from the phone connected the fxs port. I can call the phone from the eyebeem clients. And, I get both the fxs phone and eyebeam clients to ring when a call comes in through the fxo port. I have been trying to get this straightened out

Hey List, I was wondering if and how one would go about tracking file activity on a Samba server, for basic auditing purposes. I'd ideally like to see what files where edited, by whom and when. I've done some RTFM and a bit of searching around the 'net, but haven't found anything yet. Even pointers to documentation on the subject would be welcome. Thanks in advance for

Hi, I've try to enable the new loss concealment code with celt-0.6.1. I've run "configure --enable-new-plc" but I've got a missing plc.c file while compiling. It is also missing for version 0.6.0. Can you release this missing file? Thank you, Pascal CRC

Hello all Firstly thanks to everyone involved for creating CELT. It is really very useful :-) One of my targets is current generation Apple iPod with the fixed point decoder (latest version from website, 0.9.1) Based on my simple time-stamp based profiling of my running app it looks like decoding a null buffer for PLC costs a lot more than decoding a normal buffer. For example a standard

Hi all, In my setup, I'm using a framesize of 320 samples at a sample rate of 32000 Hz (10 ms frames). This gives me a mode where nbEBands is 21 and eBands[21] is 100 (the standard 2.5 ms short block ebands). This also gives me LM = 2, so what happens is eBands[nbEBands]<<LM is 400, whereas my framesize is only 320. This causes a stack overrun at line 1978 in celt.c in both calls

Hi Jean-Marc Shouldn't line 429 in celt_decoder.c be ALLOC(etmp, st->overlap, opus_val32); ? It seems that's how much memory is being written by comb_filter(). Or at least there seems to be some kind of disconnect somewhere. Cheers, John Ridges

Hi We have implemented Opus Codec with a 48 ksps and 5 ms frame running on a C5535 for a radio link. The decode time takes about 2ms, which is fine. However if PLC enabled and there is a lost packet this increases to over 6 ms, which is a major problem for our radio link. Is there any options / optimisations that make the decode time more equal when a lost packet occurs with PLC? Many thanks

What do you mean by "implement"? You're just using the Opus built-in PLC (passing NULL), right? The PLC generally attempts to find periodicity and replicate it. I guess if your signal isn't periodic it can lead to a repetition that isn't great. It's something that could probably be improved in the PLC.

I'm running Opus (both encoder and decoder) on a Cortex-M7 (using floating point), and am getting an audible artifact each time I call the decoder with a NULL for the input data pointer. Normal encoding/decoding sounds fine, but when I run a test where I pass in a NULL on every 20th frame, I can hear what sounds like a quieting of the background noise and an impure tone (each time at a

Is packet-loss concealment influenced by the complexity setting?

Hi,I want to know how to do to work PLC of Asterisk. Anyone plz help me. PLC (Packet Loss Concealment) is included in Asterisk,I read at voip-info.org or release note. And I see in codecs.conf, "genelicplc" setting. So I put codecs.conf in '/etc/asterisk' ,and wrote "genericplc => true". And I worked Asterisk and tested. I think PLC like this. When I send 3

In a fork of seanbright's opus patch for 13 there are further patches for Forward Error Correction and Package Loss Concealment, both of which ought to very useful in voip: https://github.com/traud/asterisk-opus Anybody used these patches ? Puzzled why they weren't committed to the main patch. sean

hi, i'd like to ask for a suggestion for implementing PLC (packet lost concealment). right now, i don't have PLC applied in my application. when voice data arrive from the network, i just play it right away. does having PLC require that you play something every interval? like if im expecting a voice packet say every 20ms, then i play something at that rate. either the packet that came
