You might want to take a look at the op_open_callbacks API: https://opus-codec.org/docs/opusfile_api-0.7/group__stream__open__close.html#ga5b81c0b685f3d3c9c7d7091e5536c759 libopusfile will only call your provided read() function as needed. If you don't implement the seeking functions, it will only read it in a linear order. On 04/06/2018 09:08 AM, Chris McGowan wrote: > I would like to

I am making a lightweight opus audio player. This is my portaudio callback function. But i hear a stammering song when i try to play a .opus song file. Can anybody say what is wrong or provide me link to any code which can play opus file written in c/c++(light). I tried to see some open source(vlc opus play) but was unable to follow. int MyCallback(const void* input, void* output, unsigned

The high-level design looks a lot better. I have a number of comments on the implementation details. I didn't really like the way that opus_head_projection_parse() turned out. I was originally thinking something

Hello. I have succeffully open a memory buffer from a url-opus-file with (from Pascal fpc): HandleOP := op_test_memory(BufferURL[0],PipeBufferSize, Err); op_test_open(StreamIn[x].Data.HandleOP); I can retrieve the tags infos, all seems ok. But for reading, using this gives 0 outframes: outframes := op_read_float(Data.HandleOP, at Buffer[0], Wantframesm, nil); I suspect that some callback

Hi all! When compiling the program using opusfile the #include <opus/opusfile.h> generates error that # include <opus_multistream.h> is not found. Actually it should be included as # include <opus/opus_multistream.h> just like the ogg.h in the previous line. A small patch attached. -- Best regards, Alexander -------------- next part -------------- A non-text attachment

Hi, I seem to have found a bug with seeking in opusfile in some situations, though this might be better directed to the ogg list. I?ve included a short description below and a test case C program that describes it more detail (comments) and reproduces the issue when used with a file which contains packets that have been split over a page boundary (less common than I thought). The test program is

Hello all, Sorry for the delay (got really sick last week). Attached are updated patches for libopus, libopusenc, opusfile and opus-tools. Note that the patches for libopusenc, opusfile and opus-tools are dependent on the patch for libopus. Please let me know if you have any additional followup comments or questions.

I would recommend the opusfile library, which implements seeking specifically for Opus streams. https://archive.mozilla.org/pub/opus/opusfile-0.8.zip
