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, pDecodeBuffer + ulBytesDone, ulBufferSize - ulBytesDone, 0, 2, 1, &current_section); #elif MACOSX // El cuarto parametro...

...statements. In this modification, each if() decodes one packet of data at-a-time, sequentially. Then, I ran the code on a single Processor and the decoding was successful. The changes in the ivorbisfile_example.c are as follows: while(!eof){ long ret=ov_read(&vf,pcmout,sizeof(pcmout),&current_section); if (ret == 0) { /* EOF */ eof=1; } else if (ret < 0) { /* error in the stream. Not a problem, just reporting it in case we (the app) cares. In this case, we don't. */ } else { /* we don't bother dealing with sample rate changes, etc, but...

...CMSize); This yields 167680 bytes, so tremor knows how much PCM data there is. However ov_read is just going ahead and skipping past that number reading up to 168320 bytes. So either I have to increase the size of my pvPCMBuffer by some magic number or tremor is reading to far. int current_section = 0; long iRead = 0; unsigned int uiCurrPos = 0; do { iRead = ov_read(&vf, (char*)pvPCMBuffer + uiCurrPos, 4096, &current_section); uiCurrPos += (unsigned int)iRead; } while (iRead != 0); I've tried ev...

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

...ocumentation 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 example: prevPos = ov_raw_tell(&vf); const long ret = ov_read(&vf, temp_buffer, 4096, 0, bytesPerSample, 1, &current_section); currentPos = ov_raw_tell(&vf); now, if I check, I'll find that prevPos == currentPos, how could this be true?? I tried the other seeking methods, which are time and pcm, and none of the did the same, prevPos is never equal to currentPos. so how can I solve this? thanks for your time...

I'm considering patching my copy of ogg123 to support vorbisgain tags. Is there any interest in folding this sort of patch into the main line ogg123? Has anyone done this already (or to another command line ogg player)?

...pass the slightly used FILE* to ov_open. Vorbisfile doesn't have a problem with that at all (whether it's secure enough is up to you. It is for me). -> If you're only playing one file at a time, and you encoded the file yourself from a single .wav, don't worry about the whole current_section-switching-formats thing. If any of these are not true for the general case, then feel free to correct me, but this is my experience trying to use vorbisfile to improve our game's audio system. -Marc Templin Engine and Tools Developer Her Interactive <p>--- >8 ---- List archives:...

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

...memcpy, it runs fine. I'm 99% certain that I'm trashing memory somewhere, but it's not clear why. The ov_read_float docs give this as "Typical usage", but it doesn't even compile under gcc, so it's clearly wrong: float **pcm; bytes_read=ov_read_float(&vf,pcm,&current_section); Can anyone tell me what I'm missing? I'm sure there is a good reason that pcm_channels is a triple pointer, but I don't see what it is. It seems to me that a double pointer would work fine.
