Hello everyone, I just wanted to see if anyone else is using PLC on the C55x and having success? I am seeing some issues and was curious if I was doing anything wrong/stupid or maybe I have found a bug? I am using: - the CELT library from OPUS 0.9.5 ( I checked the git repo and no check ins have comments about PLC, I assume it hasn't been updated)...

Hi, I have read the mailing list archives and have a question regarding PLC (packet loss concealment).

Thanks for the reply. I think I'm beginning to understand but can you clarify a bit more. 1) I am confused on "trade error-free quality" part. Basically the encoder is doing something to the encoded data by looking at the SPEEX_SET_PLC_TUNING parameter? 2) How does the receiver side determine whether the packet loss occured or not? It seems only way is assigning timestamps or some indexes to speex data at the encoding. Is this the case? I am currently testing using network emulator to simulate packet loss; but so far I c...

Hello all, I've noticed that removing a user from a group in /etc/group does not immediately prevent the user from accessing files / directories which the group still has access to. For example, say user 'cwseyst2' only has access to access to 'plc' if it is in group 'plc-staff'. # getfacl plc # file: plc # owner: smbadmin # group: smbadmin user::rwx group::rwx group:plc-staff:rwx group:wheel:rwx mask::rwx other::--- default:user::rwx default:group::r-x default:group:plc-staff:rwx default:group:wheel:rwx default:mask::rwx default...

I am specifically using Celt Wideband (48kHz) over WiFi multicast that naturally leads to lost packets and am trying to minimize the impact to the audio. I implemented PLC but the audio it produces is robotic. Have I implemented PLC correctly? Checking the waveform it is using the previous received waveform to fill in a missing packet but not the full waveform so it has to repeat. Basically, within a single lost 20ms packet I hear two replicas of the last 10ms of...

...nks 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 decode takes about 1ms but the PLC decodes are predictably taking either 2.6ms or 4.4ms Is PLC inefficiency a known issue? Is there a way to get it to use the same amount of CPU as a normal buffer decode? I'm happy to h...

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 th...

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 Aste...

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

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. Cheers, Jean-Marc On 08/25/2015 01:21 PM, Scott Boe...

Hi, I have a question about jitterbuffer and PLC. I use Asterisk 1.6.2.0 and 1.6.0.20 or older. I use uLaw. My system map: ============================================================================= [ asterisk 2 ] -- # LOSS # -- # A # -- [ asterisk 1 ] -- # B # -- [ X-lite ] =================================================================...

Hello I've been using VoIP over a not so reliable net: I usually get a 5% to 10% packet loss and a very high jitter. I tried several codecs and parameters, and the only thing left to test is PLC (Packet Loss Cancellement). Have the astesrisk and digium people implemented PLC?, Are they implmementing it now? and, if not, Where can i find an implementation? Thanks in advance -- Jorge Verastegui G <jorge@redcetus.com> RedCetus S.R.L.

...'net ads testjoin' works fine). I have compiled and loaded the idmap_rid module and that seems to be working fine too. wbinfo -u gives me all the domain users and wbinfo -g the groups. 'net ads info' gives me this: LDAP server: 192.168.5.4 LDAP server name: brain Realm: UK.*****.PLC Bind Path: dc=UK,dc=*****,dc=PLC LDAP port: 389 Server time: Sat, 21 May 2005 23:12:14 GMT KDC server: 192.168.5.4 Server time offset: 0 which also seems fine to me. However, the wheels come off when I try a 'getent passwd' (which returns no domain users) or 'getent passwd administrat...

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 o...
