similar to: ov_read() reading too little.

Ok here is the breakdown. I am trying to impliment streaming into our game using openAL and ogg-vorbis. In the non-streaming function when I call ov_read on the file I should be streaming the buffer gets filled with the correct data. However, when I run ov_read on the same OggVorbis_File when I read the buffer gets filled with 0's. The buffer has not been zero'd and starts filled

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 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,

Has anyone had experience using ov_read in a thread with streaming directsound buffers? i have tried the following, but it just produces a repeating garbage noise. i would appreciate some help. notes: test.ogg in my code was a song that i converted to the vorbis format (Gorillaz - Cling Eastwood) pcmData is defined like this: char pcmData[4096]; the ogg file and the directsound buffer

When I call ov_read ( ) I cannot get more then 1024 bytes decoded even when the buffer size is 4K. The function only decodes 1024 bytes max even when I tell it to decode 4096 bytes. Does anyone has an idea what is going on. <p><p>--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to

How does one deal with the case when an fread callback doesn't have any more data but is going to get more data in the future? In particular, this is an issue when reading an incoming Ogg stream from a socket (icecast2, in this case). The issue is that the fread can't return 0 (that signals EOF and hoses everything), and it doesn't have a negative code that says come back later

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, 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

Hi folks, i would like to know if it is valid to load a whole .ogg file into memory and call ov_open like this: ov_open(NULL, &OggVorbisFile, pRawData, RawDataLen); An other question is, is it valid to copy some ogg files into one (resource) file, position the filehandle and use ov_read to read only the ogg file which starts at the current position of the file handle? (In other words, does

Folks: Granted, this slipped past my review too, but do *not* submit patches that have not been tested. This bug was a no brainer; running the code only even once would have found it. The mainline of Vorbis is our face to the world. A simple mistake like this costs us credibility when we're already going to be fighting hard against some of the most powerful media organizations in the

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

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

Hi! I solved the problem using ov_read_float instead ov_read. Still do not know why ov_read returned garbage, but ov_read_float works fine! Thanks!

I'm in the final throes of debugging (hopefully) and the last thing I'm trying to do is figure out why I'm getting static instead of usable data. I have a verified Ogg file (it plays fine in WMA); I've visibly inspected the info struct and it matches my output format; I've verified my audio playback code by using a generated sine wave (sounds correct). So that leads to a

Hi guys, I'm working doing the Java->JNI->OggVorbis thing. As a test to get me going, I've just written a quick routine that dumps info about the file test.ogg in the current directory. The problem arises when I call ov_clear. I get a segfault everytime. Note that I am *not* doing any decoding (ov_read) at all, just ov_comment and ov_info. Should I only call ov_clear if I have

Hello, I'm currently trying to implement streaming off ogg-files out of an archive file using SDL and SDL_mixer for playback. Therefore i create a FILE * filepointer, place it to the beginning of an ogg file inside the archive and hand over the filepointer to ov_open. ( command: ov_open(fp, &music->vf, NULL, 0) ). This works fine so far. The problem is: if i put many oggs together in

The documentation for ov_read states: "ov_read() will decode at most one vorbis packet per invocation". Can I increase the packet size in my encoder so my decoder makes fewer calls to ov_read? -------------- next part -------------- An HTML attachment was scrubbed...

I've been experimenting with the ideas of Replay Gain[1] and find that ogg123 doesn't have a way of specifying the scaling applied to replayed samples (like -f in mpg123). Looking at libvorbisfile, I see no function exactly matching this possibly desirable behaviour. ov_read() scales by either 128 (byte output) or 32768 (word output), but there's nothing in between. ov_read_float()

Hello, Am I missing something? float** pcm_channels; int bitstream; int where = ov_pcm_tell(&vf); -> The Result is "0"; ov_read_float(&vf, &pcm_channels, 1, &bitstream); -> pcm_channels[0][0] is "0.000338580" ov_pcm_seek(&vf, 0); char* buffer = new char[2]; ov_read(&vf, buffer, sizeof(buffer), 0, 2, 1, &bitstream); short temp =

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
