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

Okay, I just came up with a possible solution. In the case of multiplexed streams, FLAC could not just keep track of its own serial number in that link, but also of the serial numbers of other streams in that link. That way, it could easily determine whether it is still in the current link, as any page will either have a known or unknown serial number. Is that also how opusfile works? I can't
