similar to: Small vorbis files with vorbisfile

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

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

When I am using vorbisfile on a disk file, ov_read does not always (in fact - most of the time) read the number of bytes I request. It doesn't seem to be dependent on the number I ask for, and the ratio between what I request and what is read varies. Can somebody tell me what's going on here?

Hi, Please excuse my ignorance but I'm having trouble with a very basic matter: I'm using vorbisfile to stream audio to the waveout device in Win32 (using waveOutWrite). I'm basically reading packets from an ogg file and streaming them using a simple buffering scheme. The thing is, this works great when the bitrate is more or less constant but the audio sounds garbled if there is a

This one may be my fault.... I've put a temporary fix for libvorbis not linking, I altered libvorbis_la_LIBADD = to libvorbis_la_LIBADD = $(OGG_LIBS) in the makefile, hence the temporary and continued with the build. I'm now getting gcc -DPACKAGE=\"libvorbis\" -DVERSION=\"1.0.0\" -DHAVE_ALLOCA_H=1 - DHAVE_ALLOCA=1 -I. -I. -I../include

I am having one frustrating time trying to decipher why ov_read is failing in my MFC/C++ application, and I see in Google results that others have had difficulty as well. These google discussions generally involve libraries, dll's and linking options, as though there are perhaps some basic incompatibilities between ogg vorbis and win32 and/or MFC/C++. Very confusing. If I pass fopen a

Should I ov_clear a failed ov_open/test/test_open call? The xmms plugin does an fclose on failure, and that seems to work, but I thought I ought to know for certain. (An observation: I think the quantity of questions and bugs raised along the lines of "I did open file, ov_open, ov_read, close file, open another file, ov_read, and it exploded", or "I tried to make vorbisfile go

Hi! I'd like to make a stereo 8-bit wav file from a stereo (16 bit) ogg vorbis file (in delphi, with the vorbisfile). I use: ret := ov_open_callbacks(filein,vf,nil,0,ops_callbacks); if ret = 0 Then begin fileOut := TFileStream.Create(savedlg.FileName,fmCreate); repeat ret := ov_read(VF, pcmout, BufferSize, 0, 1, 1, nil); //'cause of the 8-bit

More newbie questions, please bear with me =) I've got my high level code pretty well structured, and I'm now trying to decode vorbis streams on the fly using the ov_open_callbacks() routines. I can't seem to figure out how to tell it what output format I want -- is this possible? For example, I would like to be able to specify number of channels output (e.g. stereo vs. sum-to-mono

-----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

How would one go about streaming an entire ogg file from memory? That is, I'd like to read the entire file right away and then just decode as I go. I'm currently using the various functions in vorbisfile.c which read from files but it's causing intermittent stuttering in my game since the calls to ov_read sometimes experience spikes in return time. I'm guessing that these spikes

Why ov_open_callbacks(fd_, &vf, NULL, 0, OV_CALLBACKS_NOCLOSE) takes so long to open OGG file? The OGG file has just 210 MB. It takes a lot of time open the file. I am working on OGG audio recorder and player. Thanks in advance! With kind regards, Pavel

Jack, I got the asm we were working last night committed ont he beta 3 branch. It's in use in both vorbisfile:ov_read() and the lsp lookup (when using float lookups) I'd like to have a patch of the other things you did in the past day or so, even if you don't want to commit yet.

Sorry to bug you all, but I have some questions (I have beta4 at the moment; don't ask): I was reading through the VorbisFile API documentation because I'm writing code to deal with Ogg Vorbis-encoded files, and nowhere did I see a function or method for retrieving the byte-width of a stream. However, I did notice that ov_read() takes a word size as a parameter. Am I correct in assuming

Hi, I am trying to find the specs for ogg vorbis but cannot find a complete spec online, I need to know the format of the headers and what to look for in order to sync, read, write, and manipulate the format easily with some functions. I know there are some examples of the code within the ogg vorbis dev tools and there is a fileogg library that is mentioned but I have not seen this elsewhere. I

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, I need to adjust the output volume from ogg123 the same way that mpg123 has the "-f n change scalefactor [32768]" option. I need to do this within ogg123, instead of alternatives that involve pipes, such as piping the output to sox. I do not believe that this is currently possible in ogg123, and I'm looking for some suggestions as to how it can be accomplished by modifying
