Codec setting using fmtp maxaveragebitrate and OPUS_SET_BITRATE
...ll", with VoIP-out obviously we want to tune it. I am planning to use fmtp in SDP to control server/client Opus settings. Something like : - *maxplaybackrate*: a hint about the maximum output sampling rate that the receiver is capable of rendering in Hz. maxplaybackrate=8000 - *maxaveragebitrate*: specifies the maximum average receive bitrate of a session in bits per second (b/s). maxaveragebitrate=12000 I have a question about the documentation : "RTP Payload Format for Opus Speech and Audio Codec draft-spittka-payload-rtp-opus-03 maxaveragebitrate : Any positive integer...

VOIP: FEC and NARROWBAND
Hello, Is FEC supposed to work in NARROWBAND mode ?(with maxaveragebitrate=12000; maxplaybackrate=8000 ) ?I am having some confusing results, it appears that FEC is enabled in the encoder, but the decoder cannot find any packet with FEC. I am also wondering if this piece of code is correct (webrtc): /* The following is to parse the LBRR flags. */? if (opus_packet_pars...

Hey i have an interesting topic to discuss here. The main goal here is to be able to make a video call between two WebRTC endpoints registered on asterisk 13 it is a feature that definitely asterisk 13 should support . the problems that i faced with this is the following and i hope i could get an advise here. asterisk 13 vanilla version has some issues marking the video packets this complain

VOIP: FEC and NARROWBAND
...o make the best decision on a packet-per-packet basis as to whether FEC is useful considering the bit-rate, percentage of loss, and the exact audio content.

How to enable OPUS inband FEC
Hi all, I try to enable FEC in the encoder using the macro OPUS_SET_INBAND_FEC and I set the packet loss percentage to a constant value of 30%, using the macro OPUS_SET_PACKET_LOSS_PERC. Please find my encoder settings below: opus: encoder fmtp (maxplaybackrate=8000;maxaveragebitrate=24000;sprop-stereo=1;cbr=1;useinbandfec=1;usedtx=1) opus: encode bw=narrow bitrate=24000 fch=auto vbr=0 fec=1 expected loss=30 dtx=1 complex=10 At the decoder side when a packet is lost I call the decoder with the next params: opus_decode(ads->dec, NULL, 0, sampv, (int)(*sampc/ads->ch...
