similar to: ov_raw_seek doesn't work ?

Hi, I have been having some problems with ov_pcm_seek in vorbis_file:- Any seeks to a sample within the first second of the stream (i.e. < 44100 samples) fail. Seeks to samples beyond this 44100 limit are fine. It appears to be associated with vorbis_file trying to read the preceding page (odd for the beginning of the file), attempting an ov_raw_seek, then bombing out with an OV_EINVAL.

Thanks for your answer. But as I said, I don't have any problem seeking in a local file. Also, I have full control on the ogg file I play, since I encode it by myself. I first would like to know if the code I provided ( https://gist.github.com/mregnauld/3f7cdc43b02ec3bbd91641b9333ba072) is good practice when it comes to extracting and seeking in a file that is being downloaded. Thanks.

Hello, All. I am making an Ogg Vorbis decoder based on Tremor. The Vorbisfile library provides a high-level API which enables us to seek in the file, but it needs to declare a pointer to OggVorbis_File structure. Because I am supposed not to use file, so I can't use the ov_pcm_seek() or ov_raw_seek() functions to seek in the file. For decoding an Ogg Vorbis file, I first put it in

I've been playing around with using ov_test and ov_test_open as an alternative to ov_open in the xmms plugin's vorbis_check_file function. xmms never bothers to cache the result of a file check, so it tends to happen rather a lot. Unfortunately ov_test_open returns OV_EINVAL because ov_test seems to have left vf->ready_state to OPEN rather than PARTOPEN. I'm presuming this is

Turned out to be a bug in my implementation of the file callbacks (not setting up vi->end properly).

Hi folks, I'm doing a merge of my current branch onto the mainline (for testing) today. I believe it to be stable. Just a little more vorbisfile testing. After the merge, I have a few more patches to apply, then onto cascading/coupling. New stuff: Floor backend 1 and residue backend 1; both are present, but the mainline modes won't use either yet. Naturally, both are enabled for

Well, your " OggPlayer::release; OggPlayer::open; before OggPlayer::seek" seems to work! Thank you so much! Also, I'll take a look at the Opus codec, thanks for the advice! For your information, here was the problem in details: let's say I download an audio file whose length is 300 seconds. When, for example, 15 seconds of the file were downloaded, I called OggPlayer::open().

The folowing code donst work: #include <vorbis/codec.h> #include <vorbis/vorbisfile.h> #include <stdlib.h> #include <stdio.h> int main() { FILE *stdfile; OggVorbis_File vf; int tmp; stdfile=fopen("./test.ogg","r"); if( ov_test(stdfile, &vf, NULL, 0) ==0) { tmp = ov_test_open(&vf);

Hi, I'm new to mailing lists, so don't argue if I do sth wrong... I'm coding on a C++ game with Vorbis- and 5.1-Surround-compatibily. For two channels (stereo), everything's fine, but when I try to read a 6-channel-ogg, ov_read returns -131 (OV_EINVAL). That's strange, because as the specification says, it only returns OV_HOLE or OV_EBADLINK as errors [1]. Have I missed

How do I seek back to the beginning of a stream using ov_pcm_seek()? ov_pcm_seek(0) doesn't seem to do anything, though ov_pcm_tell() returns 0 right after opening the stream. I'm now using ov_pcm_seek(1) which seems to work, but I'm not sure if that's really right. Are PCM offsets meant to be 0 or 1 based? Is this a bug? Frank -- Frank Heckenbach, frank@g-n-u.de

I need to be exposed to a way of seeking theora streams. I have repeatedly found the same question asked on a different forums but could not find an answer. I'm working on a game and started integrating video with theora, the sound works just fine with ogg/vorbis(i find it easy to seek using ov_raw_seek for audio files). Could someone please point me to some example/code of how can i seek with

Hi all, I'm having a little trouble with a Vorbis decoder hanging (actually hard looping the CPU) when I call ov_pcm_seek(&vorbis_file, 0) on a multiplexed theora/vorbis file. It appears to be the vorbisfile library that has the problem. The call to ov_pcm_seek never returns. Seeking in non-multiplexed, including chained, files is OK. Seeking to other values, including sample 1, works

We compiled the vorbis_example from WIN32SDK with Borland 5.0 under WIN98. When running, it ends in an address violation caused by ov_open (or ov_test as well). This happens no matter which Library we're using, or if we're trying to read from stdin or a FILE*(which was binary). thanks, michael <p><p>_________________________________________________________________ MSN -

I seem to be having a small problem, with _f0_fit_to_clear, basically I get a segment violation when trying to seek, (it seems to take two seeks before it falls over) and for some vorbis file after playback as finished. Here's a stack crawl for the seek. loading symbols segment violation occurred _f0_fit_clear: _f0_fit_clear: +002a ea3039c6: * 103b cmpl (%eax), %edx

Hello, hope you're fine. And hopefully someone can help me. I wrote a short demonstration to show you my problem (see below). I'm asking always for 64 samples. When "ov_read_float()" is finished, I want to seek back to sample 1, and ask immediately for the next 64 samples. But when I run this small app, I get an totally high CPU load. Is there a way to it speed up? Or do I

Is there a straight forward method for seeking straight to a particular logical stream using vorbisfile? I'm guessing I'll have to look the offset for a given link up in vf->offsets, and use that in ov_raw_seek?

I'm working on an application where I need to record the current playing position and return to it later. and I need this to be done the most efficient way, so I used ov_raw_tell() and ov_raw_seek() because the documentation says they are the best when speed is a concern. but the problem is that sometimes ov_raw_tell returns the same value before and after calling ov_read; here's an

I realise the it's hard to do a seek in a variable bitrate file but I didn't think it was this bad. It seems to vary a lot with the file but the total time to do an ov_open() and ov_pcm_seek() can add upp to a second or more. By this time my DirectX buffers have wrapped around and are looping. Can anybody think of a solution for this? I really need a faster response time for my in-game

Hello all. I'm new to this list. I'm also new to coding with libvorbis and things, so please bear with me. :) I've been having trouble with libvorbisfile. My use of it is fairly simple, but when I try to ov_clear the vorbis file, it segfaults. I can attach or otherwise make availible some demo source code, but for now I'll just pull out relevant lines: //BEGIN PSEUDO CODE

Hello everybody, I sent something about this before, but this bug is still there, so... If you call ov_time_seek(vf, 0); it will fail, returning OV_EFAULT (from ov_pcm_seek_page). I think this must be a bug, because seeking to 0 seconds *should* be OK. Another thing, when ov_time_seek fails with OV_EFAULT, you cannot continue playing (because of the goto seek_error). This is not clear from
