Provides a base class for CDDA sources, which handles things like seeking, querying, discid calculation, tags, and buffer timestamping.
typedef struct { gboolean is_audio; /* TRUE if this is an audio track */ guint num; /* real track number (usually starts from 1) */ guint start; /* first sector of track (LBA, not LSN!) */ guint end; /* last sector of track (LBA, not LSN!) */ GstTagList *tags; /* NULL or tags for track (e.g. from cd-text) */ } GstCddaBaseSrcTrack;
CD track abstraction to communicate TOC entries to the base class.
gboolean is_audio ; |
Whether this is an audio track |
guint num ; |
Track number in TOC (usually starts from 1, but not always) |
guint start ; |
The first sector of this track (LBA) |
guint end ; |
The last sector of this track (LBA) |
GstTagList *tags ; |
Track-specific tags (e.g. from cd-text information), or NULL |
typedef enum { GST_CDDA_BASE_SRC_MODE_NORMAL, /* stream = one track */ GST_CDDA_BASE_SRC_MODE_CONTINUOUS /* stream = whole disc */ } GstCddaBaseSrcMode;
Mode in which the CD audio source operates. Influences timestamping, EOS handling and seeking.
GST_CDDA_BASE_SRC_MODE_NORMAL |
each single track is a stream |
GST_CDDA_BASE_SRC_MODE_CONTINUOUS |
the entire disc is a single stream |
gboolean gst_cdda_base_src_add_track (GstCddaBaseSrc *src, GstCddaBaseSrcTrack *track);
CDDA sources use this function from their start vfunc to announce the
available data and audio tracks to the base source class. The caller
should allocate track
on the stack, the base source will do a shallow
copy of the structure (and take ownership of the taglist if there is one).
src : |
a GstCddaBaseSrc |
track : |
address of GstCddaBaseSrcTrack to add |
Returns : | FALSE on error, otherwise TRUE. |
#define GST_TAG_CDDA_CDDB_DISCID "discid"
CDDB disc id in its short form (e.g. 'aa063d0f')
#define GST_TAG_CDDA_CDDB_DISCID_FULL "discid-full"
CDDB disc id including all details
#define GST_TAG_CDDA_MUSICBRAINZ_DISCID "musicbrainz-discid"
Musicbrainz disc id (e.g. 'ahg7JUcfR3vCYBphSDIogOOWrr0-')
mode
" property"mode" GstCddaBaseSrcMode : Read / Write
Mode.
Default value: Stream consists of a single track
