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 called ov_read? If I comment out the ov_clear, everything works fine. This is good, as it means I'm on the right track and I at least *parti...

I get an access violation when calling ov_clear(). I know ov_open() worked because I used ov_info to get the sampling rate and number of channels in the .ogg file. I also know the FILE pointer and the OggVorbis_File structure are still in scope (they're member variables of the same class my deconstructor is in (where ov_clear() is called))...

Hi All, Im having troubles with ov_clear crashing or just failing to close properly. Is there anything else i should make sure im doing before i call ov_clear. My code basically consists of one ogg file running completley in its own thread where it decodes into direct sound buffers. I only run 2 threads at anyone time, and ive also notic...

Hello all. I'm new to this list. I'm also new to coding with libvorbis and things, so please bear with me. :) I've been having trouble with libvorbisfile. My use of it is fairly simple, but when I try to ov_clear the vorbis file, it segfaults. I can attach or otherwise make availible some demo source code, but for now I'll just pull out relevant lines: //BEGIN PSEUDO CODE OggVorbis_File vorbis; vorbis_info *info; if(ov_open(infile, &vorbis, NULL, 0) != 0) error(); if((info = ov_info(&vorbis...

I am having no luck at all mixing libvorbisfile with the cross-platform gaming library SDL. It seems that any time I call ov_clear, the app goes unstable and crashes later in calls to glibc. This is unacceptable for obvious reasons and I was wondering if there was a way to fix it by just using libvorbis. I was going to experiment with the possibility, but I have, as yet, been unable to find any programming docs about libv...

...need a ov_info_basic function so that no internal structure is returned (which seems to me a somewhat bad design because you'll get stuck with that: each time an internal modification will occur, outer code may have to be fixed or re-compiled).

Hello! There is a problem with the VorbisFile library. It only works when I open an OGG file for the 1st time. After I closed the file and try to open another one or the same it crashs. It seems it applies to the use of either ov_open or ov_test functions or their combination. I wrote a test app that illustrates the bug. It crashs with a message "Unmapped memory exception". It's

...loca(x)) # endif # define rint(x) (floor((x)+0.5)) #endif #endif Sqrt domain errors still occur when encoding a full range pure sine wave. Is anyone else seeing that problem? An exception occasionally occurs on line 1251 of smallft.c: if(l->trigcache)free(l->trigcache); when calling ov_clear for vorbisfile. It seems to occur for the new higher bitrate files. The command line tools do not seem to cause the exception. Using old beta 1 code works fine.

...h my simple libvorbis implementation, ogg decoding works just fine for files that are 10kb or larger. For anything smaller (actually, I don't have a 9kb file, so <= 8), it seems that I get an inaccurate value for ov_pcm_total. Though ov_read returns zero, I overflow the buffer and crash on ov_clear. These are my TRACE statements: >= 10kb: Opening Audio File 'no_0.ogg' vi->channels = '2' vi->rate = '44100' pcmTotal = '15341' pcmTotal * vi->channels * 2 = '61364' BufferSize = '61364' dwBufferLength = '61364' BufferSize = ...

there can be a minor bug in vorbisfile: when opening an invalid file with ov_file the errorcode is returned as it should, but the OggVorbis_File struct can't load another file: using ov_open on the same struct with another file segfaults. also using ov_clear on the struct before reopening does'nt helps. workaround: delete and recreate new the OggVorbis_File for each opened file. -- jrml ..//korova.dyne.org 6EEE 4FB2 2555 7ACD 8496 AB99 E2A2 93B4 6C62 4800 --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http:...
