similar to: vorbisfile timestamp oddity

I think I have bumped into the small file error, or I''m doing something stupid. The files are short audio effects for a game (embedded in our own data format). Sample info: Vorbis packets: 1 (4 kb) Samples: 28672 Samplerate: 22 kHz Channels: 2 This is what I''m doing when I want to get a number of bytes from the stream: The problem is that ov_pcm_tell always returns 0. And so

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

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 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

Hello! I just got _very_ scared. I was certain the Ogg libraries could be used in commercial products (I know they are used in Star Trek: Away Team and Operation Flashpoint). I've also been told several times that it's OK, even if they're not GPL, but now I can't find any info on the sites that tells me so. Could you please tell me what the deal is (I've used it in a project

Hey guys, currently wrapping my head around the vorbisfile API. The stream callback interface is really nice ! Great work. I'm running into two snags using it though. a) getting ov_bitrate on a seakable stream returns a long. When I print it as %ld, I get Bitstream is 2 channel, 44100 Hz, 0 version, -2147483648 bitrate I get this same number for any vorbis file. I checked them with

I hope that this is the appropriate venue for this question. If it's not, let me know and I'll take it elsewhere (perhaps vorbis-dev). Saved streams are great - it lets this norteamericano get his fill of BBC Radio 1's Essential Mix. Unfortunately, saved streams aren't seekable. Running ogginfo on the stream data gives: erial=1626603590 header_integrity=pass vendor=Xiphophorus

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

Hi all, While reading through various bits of libvorbis and vorbisfile, and then thinking about how to implement other features in the xmms and winamp plugins, I had some thoughts... Vorbisfile is very useful, and very easy to use. It is, however, tied to stdio - which means you can't use it for lots of other stuff where it'd be useful - like streaming, or (under win32) avoiding stdio

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'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

Hi, How can I use vorbisfile when I've already read the data into memory of an OGG file?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm writing a simple application to decompress a set of Ogg files to raw PCM format, using vorbisfile, because that is the simplest way of doing it. These Ogg files are sounds for a game, and thus sometimes very short (about .25 s). However, vorbisfile has severe problems with Ogg files that are smaller than the CHUNKSIZE which is #defined

Hello! There is a problem with the VorbisFile library. It only works when I open an OGG file for the 1st time. After I closed the file and try to open another one or the same it crashs. It seems it applies to the use of either ov_open or ov_test functions or their combination. I wrote a test app that illustrates the bug. It crashs with a message "Unmapped memory exception". It's

OK, I have a minor problem with the 'vorbisfile' libraries. I copied both the normal and dynamic DLLs to my program directory, and they load fine. Thing is, if I link with 'vorbisfile.lib' and use 'ov_open', the application just locks up. If I link with 'vorbisfile_d.lib' and use the function, Windows brings up a standard crash window, and I can just use that to

Just noticed this article on Slashdot: http://ask.slashdot.org/article.pl?sid=04/05/18/0432202 ...about the feasibility and efficiency of reading id3v2 tags out of mp3's over http. I know that vorbisfile's callback model is well suited to handling this sort of scenario, but I'm curious to know whether ov_open will try to read enough stream to pull the comments out on a

Hi, this is my first post, I hope it's the right mailing list (or should it be vorbis@xiph.org?) I just downloaded "SDK for MacOS9" and tried to compile the "vorbisfile_example.c" sample with CodeWarrior for Mac 8 on a Mac OS 9.2 machine. I included the libOgg and libVorbis libraries in my project, but the linker cannot file ov_clear(), ov_read(), ov_pcm_total(),

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?
