Libvorbisfile contains many functions to get information about bitstream attributes and decoding status.
All libvorbisfile file information routines are declared in "vorbis/vorbisfile.h".
| function |
purpose |
| ov_bitrate |
Returns the average bitrate of the current logical bitstream. |
| ov_bitrate_instant |
Returns the exact bitrate since the last call of this function, or -1 if at the beginning of the bitream or no new information is available. |
| ov_streams |
Gives the number of logical bitstreams within the current physical bitstream. |
| ov_seekable |
Indicates whether the bitstream is seekable. |
| ov_serialnumber |
Returns the unique serial number of the specified logical bitstream. |
| ov_raw_total |
Returns the total (compressed) bytes in a physical or logical seekable bitstream. |
| ov_pcm_total |
Returns the total number of samples in a physical or logical seekable bitstream. |
| ov_time_total |
Returns the total time length in seconds of a physical or logical seekable bitstream. |
| ov_raw_tell |
Returns the byte location of the next sample to be read, giving the approximate location in the stream that the decoding engine has reached. |
| ov_pcm_tell |
Returns the sample location of the next sample to be read, giving the approximate location in the stream that the decoding engine has reached. |
| ov_time_tell |
Returns the time location of the next sample to be read, giving the approximate location in the stream that the decoding engine has reached. |
| ov_info |
Returns the vorbis_info struct for a specific bitstream section. |
| ov_comment |
Returns attached comments for the current bitstream. |
