I’m running into a problem with my application crashing when I make a call to the ov_time_seek() function. The call includes the OggVorbis_File and it is indeed seekable, as I first check that using the ov_seekable() function. Everytime, however I try to seek forward, the application dies with a core dump. I’m working with the example from the “VorbisFile Documentation” site. The application is compiled using gcc version 2.96 20000731 on a Red Hat Linux 7.0 system (Intel). Has anyone else experienced...

How can I decode a Vorbis file which is in RAM (not in a file on the disk)??

When calling ov_open_callbacks(), is it safe to have seek_func, tell_func, and close_func all equal to NULL? If not, which ones must I provide and how can I return an error e.g., data source is not seekable? -- Ignacio Vazquez-Abrams <ignacio@openservices.net> --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from

...code: if (ov_open(NULL, &vf, const_cast<char*>(reinterpret_cast<const char*>(get_data())), get_size()) < 0) error = 0x100; else { vorbis_info* vi = ov_info(&vf, -1); Cvirtual_file f; const int cb_samples = ov_pcm_total(&vf, -1); const bool seekable = ov_seekable(&vf); So all data is already in memory and passed to ov_open. This stream is not seekable. Why not? And shouldn't it be seekable?

...ow store the internal state ready for a fast startup? There's a lot of files and various seek points within each one so I'm not keen on having an open OggVorbis_File for each file/seek point, that seems a little inelegant to me. I imagine I'd also need to start creating other threads to ov_seek() them back to the right place after each use, ready for the next time around. Gak! Anybody have any ideas...can I somehow grab the internal state of a decoder into a buffer then restore it? -- <\___/> / O O \ \_____/ FTB. --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg...
