Hi, I'm curious to know when would be the 1.1.1 stable version available. In 1.1, we are facing crash when opus library is trying to decode the CELT-only, full band and 20 ms. So we tried with 1.1.1 beta and it looks to be fine. Is there any open issue regarding this in 1.1 version? Thanks Suresh -------------- next part -------------- An HTML attachment was scrubbed...

1 is the way to use FEC. But: How do I know if this *previous* packet contains FEC information? If not, I want to fallback to invoking PLC for obtaining samples. Or does the decode_fec call automatically use PLC internally as a fallback if FEC is not available?

...pected 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), 0); and set the flag packet_lost=true; When I receive the next packet, I'm trying to decode the packet with decode_fec = 1 and then the same packet with decode_fec = 0: In the code below, suggest to replace ‘ads->ch’ with ‘numChannels’ to make it more clear to what you refer to.) if(packet_lost ) { if(opus_packet_has_fec(buf, (opus_int32)len, sample_rate)) { fec_samples = opus_packet_get_samples_per_fram...

...n be used. Is this possible, and if so, what is the recommended way of doing it? Which component(s) would be responsible for handling FEC: the muxer (e.g. by extracting FEC data from a previous packet and inserting this instead of a zero-byte frame), the ogg player (by calling the opus decoder with decode_fec=1 whenever necessary), or the opus decoder itself? I failed to find any information about this specific topic. Please point me to relevant documentation if it exists.

Hi guys,

Hello, I understand the encoder provides an option for FEC to provide some protection against packet loss, but I don't understand the details of this arrangement. I'd appreciate answers to the following: * Adding FEC seems to change the encoded audio bit-stream itself, i.e., it doesn't just add additional protection bits, but also changes the encoded bits. This is easy to show by
