Property Details

The “audio-sink” property

  “audio-sink”               GstElement *

Set the used audio sink element. NULL will use the default sink. playsink must be in GST_STATE_NULL

Flags: Read / Write


The “av-offset” property

  “av-offset”                gint64

Control the synchronisation offset between the audio and video streams. Positive values make the audio ahead of the video and negative values make the audio go behind the video.

Flags: Read / Write

Default value: 0


The “flags” property

  “flags”                    GstPlayFlags

Control the behaviour of playsink.

Flags: Read / Write

Default value: Render the video stream|Render the audio stream|Render subtitles|Use software volume|Use software color balance


The “force-aspect-ratio” property

  “force-aspect-ratio”       gboolean

When enabled, scaling will respect original aspect ratio.

Flags: Read / Write

Default value: TRUE


The “mute” property

  “mute”                     gboolean

Mute the audio channel without changing the volume.

Flags: Read / Write

Default value: FALSE


The “sample” property

  “sample”                   GstSample *

Get the currently rendered or prerolled sample in the video sink. The GstCaps in the sample will describe the format of the buffer.

Flags: Read


The “send-event-mode” property

  “send-event-mode”          GstPlaySinkSendEventMode

How to send events received in send_event function.

Flags: Read / Write

Default value: Default GstBin's send_event handling (default)


The “subtitle-encoding” property

  “subtitle-encoding”        gchar *

Encoding to assume if input subtitles are not in UTF-8 encoding. If not set, the GST_SUBTITLE_ENCODING environment variable will be checked for an encoding to use. If that is not set either, ISO-8859-15 will be assumed.

Flags: Read / Write

Default value: NULL


The “subtitle-font-desc” property

  “subtitle-font-desc”       gchar *

Pango font description of font to be used for subtitle rendering.

Flags: Write

Default value: NULL


The “text-sink” property

  “text-sink”                GstElement *

Set the used text sink element. NULL will use the default sink. playsink must be in GST_STATE_NULL

Flags: Read / Write


The “video-sink” property

  “video-sink”               GstElement *

Set the used video sink element. NULL will use the default sink. playsink must be in GST_STATE_NULL

Flags: Read / Write


The “vis-plugin” property

  “vis-plugin”               GstElement *

the visualization element to use (NULL = default).

Flags: Read / Write


The “volume” property

  “volume”                   gdouble

Get or set the current audio stream volume. 1.0 means 100%, 0.0 means mute. This uses a linear volume scale.

Flags: Read / Write

Allowed values: [0,10]

Default value: 1


The “audio-filter” property

  “audio-filter”             GstElement *

Set the audio filter element/bin to use. Will apply on a best-effort basis unless GST_PLAY_FLAG_FORCE_FILTERS is set. playsink must be in GST_STATE_NULL

Flags: Read / Write


The “video-filter” property

  “video-filter”             GstElement *

Set the video filter element/bin to use. Will apply on a best-effort basis unless GST_PLAY_FLAG_FORCE_FILTERS is set. playsink must be in GST_STATE_NULL

Flags: Read / Write

Signal Details

The “convert-sample” signal

GstSample*
user_function (GstPlaySink *playsink,
               GstCaps     *caps,
               gpointer     user_data)

Action signal to retrieve the currently playing video sample in the format specified by caps . If caps is NULL, no conversion will be performed and this function is equivalent to the “sample” property.

Parameters

playsink

a GstPlaySink

 

caps

the target format of the sample

 

user_data

user data set when the signal handler was connected.

 

Returns

a GstSample of the current video sample converted to caps. The caps in the sample will describe the final layout of the buffer data. NULL is returned when no current sample can be retrieved or when the conversion failed.

Flags: Action


The “reconfigure” signal

gboolean
user_function (GstPlaySink *gstplaysink,
               gpointer     user_data)

Flags: Action
