...he SDP requests and RTP packets into files. Then I made a java decoder based on jitsi. Although the files contain all the needed info: encription keys, codec info, timestamps, etc., I could only decode one side in one of 2 conversations. For example, the RTP payload is decrypted successfully, but opus_packet_get_nb_samples() or opus_decode() return OPUS_INVALID_PACKET. payload-0.dat , contains my real voice. Decoded successfully. https://docs.google.com/file/d/0B40Hp1Tx6I6eaHJaRjBKY1M0WnM/edit payload-1.dat , contains looped beep recorded with a virtual microphone. While recording I was hearing it, but I can't...

..._samples() on 1st packet returns reasonable number 960, but then opus_decode() fails.

Hi all, I'm working on fuzzing Opus with OSS-Fuzz and have started with the decoder. Attached is a patch to add the corresponding fuzz target. Please let me know if there are any concerns?

...EC for packets with multiple Opus frames - Hybrid mode quality improvements and fixes - Fixed bugs in the CELT mode PLC - Redundant mode transition fixes Other changes - Stack reduction - Doc fixes (many) - 16-bit fixes - Misc build fixes - New API calls: OPUS_GET_LAST_PACKET_DURATION ctl() and opus_packet_get_nb_samples() - Minor code cleanup As usual, this release is fully compliant with the Opus specification. Cheers, Jean-Marc

Hi Felicia, Here's a few comments/questions on your patch: > static void ParseToc(const uint8_t toc, TocInfo *const info) { Any particular reason you don't use the Opus functions for parsing the ToC? It seems like opus_packet_get_nb_samples(), opus_packet_get_bandwidth(), and opus_packet_get_nb_channels() should do the trick. > int LLVMFuzzerTestOneInput(const uint8_t *data, size_t size) How is that function supposed to work? I noticed that it will only decode a single packet. How does the fuzzer handle testing for bugs that only...

Hi, I'm trying to use the FEC feature. I have a service which does the encoding with OPUS_SET_INBAND_FEC(1) and OPUS_SET_PACKET_LOSS_PERC(20) with 10ms packets. I'm not clear on the decoding process though. 1- When a packet is lost, do I need to call decode with fec=1 ONLY or do I need to call decode with fec=0 after as well? 2- How do I know up front the size of the pcm that I send to
