similar to: re: Seek problems with vorbis_file

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.

I found a problem with ov_raw_seek function in oggvorbis win32sdk 1.0. When i called this function it returned OV_EINVAL immediatelly. I solved the issue by replacing the ov_raw_seek by ov_pcm_seek, which worked perfectly, but i would like to use the raw variant due to performace reason . Is anybody aware of this strange behaviour ?

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

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

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

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().

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

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

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.

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

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

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);

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

Not too long ago, I converted my whole cd library to OGG format, because I loved the way it sounded, and the fact that is was open source. Recently, I wanted to update my library with the latest CVS code. I just did a compile of the CVS ogg binaries (ogg.dll, vorbis.dll, vorbis_enc.dll, vorbis_file.dll), and I noticed they were alot larger in size than the default ones that came with CDex. I

ok, I'm aware that vo_open cant be used at the same time as other functions such as ogg_sync_wrote, ogg_sync_pageout, ogg_stream_pagein, ogg_stream_packetout and vorbis_synthesis_headerin. In order to get information from the bitstream i've been using this method because it's fast and doesn't require decoding of the stream. But, i can only retrieve the average bitrate of

I'm seeing some inconsistency in returned timestamps using vorbisfile. I open a file, read some data (grabbing timestamps with ov_pcm_tell), then seek back with ov_pcm_seek(vf, 0) and read it again. The seek lands back on 0, but on the second read through, there's a gap in the timestamps: they jumps up by 2112 frames. This causes my vorbisfile code to insert silence to maintain sync (as

I have been having problems compling vorbis on my computer( running redhat 7.1 ), it gives me a bunch of errors about vorbisfile.o( at least that what the errors are complaining about...I don't know enough to figure out what is wrong ). Below is the output I get from compile: Making all in examples make[1]: Entering directory `/home/mchavez/devel/vorbis/examples' /bin/sh ../libtool

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

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?
