I've been playing around with using ov_test and ov_test_open as an alternative to ov_open in the xmms plugin's vorbis_check_file function. xmms never bothers to cache the result of a file check, so it tends to happen rather a lot. Unfortunately ov_test_open returns OV_EINVAL because ov_test seems to have left vf->ready_state to OP...

...add .ogg support to my engine project. First i had the problem quite a lot had out there with a crashing/freezing call to ov_open which i solved by recompiling those libs against the single-threaded variant of the core libs using VC++ 6 But now i have another problem. now every call to ov_open or ov_test or whatever returns OV_EREAD, no matter which file i use. I am perfectly positive on thos .ogg files beeing correct as several tools can load and play them back alright. Since the given explanation string "A read from media returned an error" isn't really self-explanatory i was hopin...

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 available at http://home.earthlink.net/~yurigulyaev/oggvorbisproject32.sit.hqx My platform is Mac OS 9.2 and CodeWarrior 8.0. I got the same result w...

...his sort of scenario, but I'm curious to know whether ov_open will try to read enough stream to pull the comments out on a non-seekable stream. I've only played around with it on seekable streams, where it tries to scan the whole stream to get a count of the logical streams within. Would ov_test get enough header read to determine the size of the comment before sucking it all in for parsing?

...ore than 100x faster (and even faster than that on a network file system), and the other seek functions (that do actually require some internal background PCM decode to get sample boundaries right) are a shade under 2x faster (again, much larger margin on distributed file systems). I also added an ov_test() function as a fast partial open that verifies the vorbis-ness of a file (and loads the headers for perusal), but doesn't seek to learn the chain structure or total length. A partially open file can then be fully opened using ov_test_open(). Libvorbis now has an official vorbis_packet_bloc...

I found a problem with ov_raw_seek function in oggvorbis win32sdk 1.0. When i called this function it returned OV_EINVAL immediatelly. I solved the issue by replacing the ov_raw_seek by ov_pcm_seek, which worked perfectly, but i would like to use the raw variant due to performace reason . Is anybody aware of this strange behaviour ?

We compiled the vorbis_example from WIN32SDK with Borland 5.0 under WIN98. When running, it ends in an address violation caused by ov_open (or ov_test as well). This happens no matter which Library we're using, or if we're trying to read from stdin or a FILE*(which was binary). thanks, michael <p><p>_________________________________________________________________ MSN - More useful every day http://www.msn.de --- >8 --...

ok, I'm aware that vo_open cant be used at the same time as other functions such as ogg_sync_wrote, ogg_sync_pageout, ogg_stream_pagein, ogg_stream_packetout and vorbis_synthesis_headerin. In order to get information from the bitstream i've been using this method because it's fast and doesn't require decoding of the stream. But, i can only retrieve the average bitrate of
