similar to: Is it possible to seek different Ogg Vorbis encoded packets from the File?

Hi, I'm new to writing any kind of sound program and somewhat new to C. I am on linux and I've been trying to get the example code (http://www.xiph.org/ogg/vorbis/doc/vorbisfile/example.html)for the decoder using libvorbisfile to work. I think my main problem is output to /dev/dsp. If I use the example where the only change I made were to open a file instead of using stdin and I ouput

Hi All, I have downloaded the Vorbis Codec source code for Windows. How do I compile, build and run it? Do I need VisualC compiler for that? Also, please tell me how do I test it? Is there a easier way of accomplishing the above in Linux? Thanks, Niranjan -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi Gunter, I've solved the sound glitch. Since it was hard to reproduce, it took me a while, but I eventually figured it out. What I needed to do was fill the buffer with more data before handing it off to ao_play. It requires lots of bookkeeping, pointer arithmetic, and a sufficiently large buffer. First, the bigger buffer. I just pulled this code from ogg123: #define PRIMAGIC

Hi, I have this code to decode ogg data: unsigned long PSS_OggStream::DecodeOggVorbis(OggVorbis_File *psOggVorbisFile, char *pDecodeBuffer, unsigned long ulBufferSize, unsigned long ulChannels) { int current_section; long lDecodeSize; unsigned long ulSamples; short *pSamples; unsigned long ulBytesDone = 0; while (true) { #ifdef WIN32 lDecodeSize = ov_read(psOggVorbisFile,

I have a wav file which has been converted to an ogg file with libvorbis via ffmpeg. However I've tested a few files just to make sure. I run a standard while loop to using ov_read to pull all the data out of ogg file. Using 4096 as the size to read each call. Watching my debug logs it is reading 2048 bytes each call. When I load the wav file the data chunk for the pcm data is 167680

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

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 am trying, for the first time, to decode and play an ogg file with two buffers. My audio is choppy and I can't see a problem on the wavOutxxx end of things. So I am wondering about how I call ov_read. From my TRACE statements, the read seems to work perfectly, eventually returning zero. Is it a simple matter of making the same call to ov_read, aside from changing the buffer and

Hello - I send this to the vorbis-dev list yesterday, but I’m working if it would not have been better targeted at this list.

I'm a developer for a game company and I'm almost done adding support for Vorbis to our game engine. As such, I wanted to simply plug in the read function, let it decode, and then send the PCM data on to DirectSound just like I always have. There were several occasions where I spent 4 or 5 hours trying to fix a bug, digging through newsgroups and sound-format specs, when that info could

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

Hi Gunter, I think this problem started happening when I upgraded from Debian Wheezy to Debian Jessie. If nothing looks amiss in my code, it probably is a sound driver problem. But since it works 100% of the time in ogg123, I feel I must have missed some corner case. My audio driver is almost always active. I usually have my music player going in the background when I do my testing. The problem

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

Hello, I was wondering if there is a way top specify rsync to replace only different block in case of in-place update. When I rsync a huge binary file that change often to a Copy-On-Write filesystem for backing it up (ZFS in my case, but I suppose that btrfs will act the same way) ; rsync replaces the whole file even with '--inplace' and so snapshots are inefficient.
