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

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

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 guys, I'm writing a sample playback engine using vorbisfile, but I've hit a performance problem - hoping someone here can help! I'm using ov_open_callbacks() to decode memory-based ogg files. It works OK, but when I call ov_open_callbacks() approximately 300k of memory is used (presumably to initialise the decoder). It also takes some time to execute ov_open_callbacks() - the read

Dear members, since two weeks I am stuck, trying to demux a physical ogg stream (theora and vorbis) and play the audio part using vorbisfile. I hope that one of you can give me a hint or point me to additional documentation. I used ogg.h and vorbisfile.h. The way so far: - initializing an ogg_sync_state - inserting data to sync_state using ogg_sync_buffer - when whole page found

Hi: I've been experimenting with streaming vorbis across my network from the windows box to an icecast2 server on my linux machine (the server I usually use is having some network issues at present). I've tested both ostream 0.7.1 and oddcast beta26. It seems that neither can encode on the fly on my P2-266 at 44100 fast enough to be able to stream it. Ostream looked the more promising

Hello - I have two files which play back in VLC correctly. They were encoded using this command: ffmpeg -y -i '/tmp/2e905b981d30324f9a0664cbabb3f59a20170406-21128-r0neh9.wav' -acodec libvorbis '/tmp/2e905b981d30324f9a0664cbabb3f59a20170406-21128-r0neh920170406-21128-146yyex.ogg However ov_pcm_total reports a zero length for one of the two files. Is this a problem with my use of the

Hello, All. First, I want to thank Ian Malone and Ralph Giles, thanks for your kind replies. But I still have problems about seek. As you suggested, I could use ov_open_callbacks() to supply my own read/write/seek functions. So, can you give me an example? I?m sorry for my ignorance, because I haven?t used callbacks before. I analyzed the vorbisfile.c in Tremor, and I think I

I want to use Vorbis to stream music off the HD in my DirectX app. Currently, we have a generic streamer that writes raw digital sound data into the primary sound buffer. We plug sound sources (e.g. wav files, PCM files) into this streamer by having the sound sources have an interface something like this: class SourceDataSourceInterface{ virtual bool Init(char* pSource) = 0;

How can I decode a Vorbis file which is in RAM (not in a file on the disk)??

Hi` Is there some example code on how to use ov_open_callbacks with VorbisFile? The documentation I found is _very_ sparse and if possible I don't want to spend much time adding streaming from memory to my code. http://www.xiph.org/ogg/vorbis/doc/vorbisfile/ov_callbacks.html <p>Thanks, -- Daniel, Epic Games Inc. <p>--- >8 ---- List archives: http://www.xiph.org/archives/

Hello, I've been looking to the libvorbisfile and got into troubles when trying to use it: I need to compile it on a PalmOS and the libvorbisfile must be compiled in ARM whereas calling code is in 68K. This implies that the interface ov_open_callback is not usable because the OggVorbis_File *vf must point to something in the target architecture (ARM) whereas the caller cannot do that. As

The latest CVS update of libvorbis fails to compile on SuSE Linux 6.4. The error is below. Also, what happened to the xmms plugin directory in cvs? It complains that it is missing when I do a 'cvs update'. gcc -DPACKAGE=\"libvorbis\" -DVERSION=\"1.0beta3\" -DHAVE_ALLOCA_H=1 -DHAVE_ ALLOCA=1 -I. -I. -I../include -O20 -ffast-math -mno-ieee-fp -D_REENTRANT -fs

Help is needed ! I cannot extract infos from video stream in an .ogm file using the VorbisFile library. It seems that I can only open .ogg files (audio)! When I call "ov_open_callbacks" it generates a message error. Here is my procedure in pascal: code: _____ procedure GetOGMInfo; var F : TFileStream; vf: OggVorbis_File; res: integer; begin F :=

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

I'm updating my vorbis rpm spec file, and when I try to do "make -C vorbis-tools ogg123", due to rpm's build environment, I get lots of: gcc ogg123.o -o ogg123 -lm ../lib/libvorbis.a ../lib/vorbisfile.a ../lib/vorbisfile.a(vorbisfile.o): In function `_get_prev_page': vorbisfile.o(.text+0x54): undefined reference to `ogg_sync_reset' vorbisfile.o(.text+0xa9): undefined

Okay - so I stepped through the code slowly this morning making notes as I went. And I can see what’s wrong. The last Ogg header of the troublesome file contains -1 as the granule position. The spec says this has a special meaning "A special value of '-1' (in two's complement) indicates that no packets finish on this page." 4F 67 67 53 00 04 FF FF FF FF FF FF FF FF 16 A2
