- Error return codes possible from libvorbis and libvorbisfile:
- All 'failure' style returns are <0; this either indicates a generic
- 'false' value (eg, ready? T or F) or an error condition. Code can
- safely just test for < 0, or look at the specific return code for more
- detail.
- *** Return codes:
- OV_FALSE The call returned a 'false' status (eg, ov_bitrate_instant
- can return OV_FALSE if playback is not in progress, and thus
- there is no instantaneous bitrate information to report.
- OV_HOLE libvorbis/libvorbisfile is alerting the application that
- there was an interruption in the data (one of: garbage
- between pages, loss of sync followed by recapture, or a
- corrupt page)
- OV_EREAD A read from media returned an error.
- OV_EFAULT Internal logic fault; indicates a bug or heap/stack
- corruption.
- OV_EIMPL The bitstream makes use of a feature not implemented in this
- library version.
- OV_EINVAL Invalid argument value.
- OV_ENOTVORBIS Bitstream/page/packet is not Vorbis data.
- OV_EBADHEADER Invalid Vorbis bitstream header.
- OV_EVERSION Vorbis version mismatch.
- OV_ENOTAUDIO Packet data submitted to vorbis_synthesis is not audio data.
- OV_EBADPACKET Invalid packet submitted to vorbis_synthesis.
- OV_EBADLINK Invalid stream section supplied to libvorbis/libvorbisfile,
- or the requested link is corrupt.
- OV_ENOSEEK Bitstream is not seekable.
