1Error return codes possible from libvorbis and libvorbisfile: 2 3All 'failure' style returns are <0; this either indicates a generic 4'false' value (eg, ready? T or F) or an error condition. Code can 5safely just test for < 0, or look at the specific return code for more 6detail. 7 8*** Return codes: 9 10OV_FALSE The call returned a 'false' status (eg, ov_bitrate_instant 11 can return OV_FALSE if playback is not in progress, and thus 12 there is no instantaneous bitrate information to report. 13 14OV_HOLE libvorbis/libvorbisfile is alerting the application that 15 there was an interruption in the data (one of: garbage 16 between pages, loss of sync followed by recapture, or a 17 corrupt page) 18 19OV_EREAD A read from media returned an error. 20 21OV_EFAULT Internal logic fault; indicates a bug or heap/stack 22 corruption. 23 24OV_EIMPL The bitstream makes use of a feature not implemented in this 25 library version. 26 27OV_EINVAL Invalid argument value. 28 29OV_ENOTVORBIS Bitstream/page/packet is not Vorbis data. 30 31OV_EBADHEADER Invalid Vorbis bitstream header. 32 33OV_EVERSION Vorbis version mismatch. 34 35OV_ENOTAUDIO Packet data submitted to vorbis_synthesis is not audio data. 36 37OV_EBADPACKET Invalid packet submitted to vorbis_synthesis. 38 39OV_EBADLINK Invalid stream section supplied to libvorbis/libvorbisfile, 40 or the requested link is corrupt. 41 42OV_ENOSEEK Bitstream is not seekable. 43 44 45**************************************************************** 46*** Libvorbis functions that can return failure/error codes: 47 48int vorbis_analysis_headerout() 49 OV_EIMPL 50 51int vorbis_analysis_wrote() 52 OV_EINVAL 53 54int vorbis_synthesis_headerin() 55 OV_ENOTVORBIS, OV_EVERSION, OV_EBADHEADER 56 57int vorbis_synthesis() 58 OV_ENOTAUDIO, OV_EBADPACKET 59 60int vorbis_synthesis_read() 61 OV_EINVAL 62 63**************************************************************** 64*** Libvorbisfile functions that can return failure/error codes: 65 66int ov_open_callbacks() 67 OV_EREAD, OV_ENOTVORBIS, OV_EVERSION, OV_EBADHEADER, OV_FAULT 68 69int ov_open() 70 OV_EREAD, OV_ENOTVORBIS, OV_EVERSION, OV_EBADHEADER, OV_FAULT 71 72long ov_bitrate() 73 OV_EINVAL, OV_FALSE 74 75long ov_bitrate_instant() 76 OV_FALSE 77 78ogg_int64_t ov_raw_total() 79 OV_EINVAL 80 81ogg_int64_t ov_pcm_total() 82 OV_EINVAL 83 84double ov_time_total() 85 OV_EINVAL 86 87int ov_raw_seek() 88 OV_ENOSEEK, OV_EINVAL, OV_BADLINK 89 90int ov_pcm_seek_page() 91 OV_ENOSEEK, OV_EINVAL, OV_EREAD, OV_BADLINK, OV_FAULT 92 93int ov_pcm_seek() 94 OV_ENOSEEK, OV_EINVAL, OV_EREAD, OV_BADLINK, OV_FAULT 95 96int ov_time_seek() 97 OV_ENOSEEK, OV_EINVAL, OV_EREAD, OV_BADLINK, OV_FAULT 98 99int ov_time_seek_page() 100 OV_ENOSEEK, OV_EINVAL, OV_EREAD, OV_BADLINK, OV_FAULT 101 102long ov_read() 103 OV_HOLE, OV_EBADLINK 104
