...r -7 (OPUS_ALLOC_FAIL). I'm compiling it with the USE_ALLOCA flag. I also tried to compile it with the flags OVERRIDE_OPUS_ALLOC OVERRIDE_OPUS_FREE 'opus_alloc(x)=NULL' and 'opus_free(x)=NULL', but still having no success. The code I wrote is: int size; int error; OpusDecoder* dec; size = opus_decoder_get_size(1); dec = (OpusDecoder *) malloc(size); error = opus_decoder_init(dec, 8000, 1); I also tried this code: int error; OpusDecoder *dec; dec = opus_decoder_create(8000, 1, &error); In this particular case, I got an error and the firmwa...

Hi, I am new to Opus, I want to use Opus and opus-tool for opus website. I just have Opus payload raw stream from RTP packets. Suppose, I have one packet, like Raw packet = RTP Header + opus payload ( The opus payload has 20 msec, and 1 channel only) I removed the RTP header and now i have only opus payload = Raw packet - RTP Header The opus payload is now (1 byte TOC) and rest of N-1 bytes

...rking malloc()", so none of the calls to the *_create() functions can work, it's normal that you're seeing those fail with OPUS_ALLOC_FAIL because there's no way the library is able to allocate memory. > The code I wrote is: > > int size; > int error; > OpusDecoder* dec; > > size = opus_decoder_get_size(1); > dec = (OpusDecoder *) malloc(size); > error = opus_decoder_init(dec, 8000, 1); This version should actually work and I don't see how opus_decoder_init() could return OPUS_ALLOC_FAIL since it's not allocating anything...

Maybe i found the source of the problem. The basestation is running several threads. One per sending client and one per receiving client. In each thread there is either an opus_encode() or an opus_decode() but there is in total only one OpusEncoder and one OpusDecoder defined which where used in every thread. Now every thread has it own OpusEncoder or OpusDecoder. After 20minutes of audiostreaming there is not even one occurance of the previous described problem. Kind regards, Jan

...of-bounds read. It would be good to add a check for the overflow even if most cases won't allow that much data to be fed to the decoder. Here is a reproducer: #include <string.h> #include "opus.h" unsigned char in_buf[16909318]; unsigned short out_buf[11520]; int main() { OpusDecoder *decoder; int result; int error; in_buf[0] = 0xff; in_buf[1] = 0x41; memset(in_buf + 2, 0xff, 16909315); in_buf[16909317] = 0x0b; decoder = opus_decoder_create(48000, 2, &error); result = opus_decode(decoder, in_buf, 16909318, out_buf, 5760, 0); } Here is the patch I'm s...
