flu_thumbnailer_new ()
FluThumbnailer * flu_thumbnailer_new (void);
Creates a new FluThumbnailer
Returns
The newly created thumnailer
flu_thumbnailer_free ()
void flu_thumbnailer_free (FluThumbnailer *thiz);
Frees an FluThumbnailer
Parameters
flu_thumbnailer_open ()
gboolean flu_thumbnailer_open (FluThumbnailer *thiz, gchar *input, gboolean disable_hw_accel, GError **error);
Opens a file with an FluThumbnailer
Parameters
thiz
The FluThumbnailer
input
The input file to use
disable_hw_accel
Disables hardware acceleration
error
NULL if the input file opened correctly
Returns
TRUE if successful, FALSE otherwise
flu_thumbnailer_close ()
void flu_thumbnailer_close (FluThumbnailer *thiz);
Closes an FluThumbnailer
Parameters
flu_thumbnailer_frame_rgb_get ()
gboolean flu_thumbnailer_frame_rgb_get (FluThumbnailer *thiz, gint64 position, gboolean accurate, FluStreamVideoRgbFormat format, gint *width, gint *height, guint8 **data, guint32 *pitch);
Takes a RGB thumbnail at a stream position
Parameters
thiz
The FluThumbnailer
position
The position in the stream
accurate
Indicates wether the position can be approximated
format
The FluStreamVideoRgbFormat format to use
width
The desired with of the frame (-1 to use the native width)
height
The desired with of the frame (-1 to use the native height)
data
The pointer to get the frame data from. In case of NULL the library will allocate the memory for you and you should use free().
pitch
The pitch of the frame. The number of pitches depend on the format used. In case data is NULL the pitch value will be set
Returns
TRUE if successful, FALSE otherwise
flu_thumnailer_frame_ycbcr_get ()
gboolean flu_thumnailer_frame_ycbcr_get (FluThumbnailer *thiz, gint64 position, gboolean accurate, FluStreamVideoYcbcrFormat format, gint *width, gint *height, guint8 **planes, guint32 *pitches);
Takes a YCbCr thumbnail at a stream position
Parameters
thiz
The FluThumbnailer
position
The position in the stream
accurate
Indicates wether the position can be approximated
format
The FluStreamVideoYcbcrFormat format to use
width
The desired with of the frame (-1 to use the native width)
height
The desired with of the frame (-1 to use the native height)
planes
The planes pointer to store the pixels. The number of planes depend on the format used. The actual pointers can be NULL in such case the library will allocate the memory for you and you should use free() on each plane value.
pitches
The pitch for each plane. The number of pitches depend on the format used. In case the planes pointers are NULL the pitches values will be set.
Returns
TRUE if successful, FALSE otherwise
flu_thumbnailer_frame_save ()
gboolean flu_thumbnailer_frame_save (FluThumbnailer *thiz, gint64 position, gboolean accurate, FluStreamVideoFrameFormat format, gint width, gint height, gchar *location);
Saves a frame at a stream position into an image file
Parameters
thiz
The FluThumbnailer
position
The position in the stream
accurate
Indicates wether the position can be approximated
format
The FluStreamVideoFrameFormat format to use
width
The desired with of the frame (-1 to use the native width)
height
The desired with of the frame (-1 to use the native height)
location
The file path to save the file (not a URI)
Returns
TRUE if successful, FALSE otherwise
flu_thumbnailer_duration_get ()
gboolean flu_thumbnailer_duration_get (FluThumbnailer *thiz, gint64 *duration);
Gets the duration of the media set
Parameters
Returns
TRUE if the duration is valid, FALSE otherwise
Types and Values
FluThumbnailer
typedef struct { } FluThumbnailer;
An opaque structure representing a thumbnailer instance.
