Detailed Description

Paraslash's ogg vorbis decoder.

Macro Definition Documentation

OV_EXCLUDE_STATIC_CALLBACKS

#define OV_EXCLUDE_STATIC_CALLBACKS

Avoid warnings on NetBSD.

The static ogg-vorbis callback structures are only needed on Windows. At least with vorbistools-1.3.7, they cause warnings on NetBSD-10.0. The define below instructs the preprocessor to not define these structures, avoiding the warnings. See the comment in vorbisfile.h for details.

ENDIAN

#define ENDIAN   0

Determine byte sex.

OGGDEC_MAX_OUTPUT_SIZE

#define OGGDEC_MAX_OUTPUT_SIZE   (96 * 1024)

Suspend decoding if output queue size is larger than that.

OGGDEC_OUTPUT_CHUNK_SIZE

#define OGGDEC_OUTPUT_CHUNK_SIZE   (32 * 1024)

Allocate chunks of this size and produce at most one chunk of output per ->post_monitor() invocation.

If the buffer could only be filled partially due to insufficient input being available, it is shrunk to the real output size and the resized buffer is fed into the output queue.
