## Description

Capture Video from a BlackMagic DeckLink Device.

#### Sample pipeline

    gst-launch-1.0 \
      decklinkvideosrc device-number=0 connection=sdi mode=1080p25 ! \
      autovideosink

Capturing 1080p25 video from the SDI-In of Card 0. Devices are numbered starting with 0.

### Duplex-Mode:

Certain DechLink Cards like the Duo2 or the Quad2 contain two or four independant SDI units with two connectors each. These units can operate either in half- or in full-duplex mode.

The Duplex-Mode of a Card can be configured using the `duplex-mode`-Property. Cards that to not support Duplex-Modes are not influenced by the property.

#### Half-Duplex-Mode (default):

By default decklinkvideosrc will configure them into half-duplex mode, so that each connector acts as if it were an independant DeckLink Card which can either be used as an Input or as an Output. In this mode the Duo2 can be used as as 4 SDI In-/Outputs and the Quad2 as 8 SDI In-/Outputs.

       video/x-raw,width=1920,height=1080 ! \
       autovideosink

Capture 1080p25 from the first 4 units in the System (ie. the 4 Connectors of a Duo2 Card) and compose them into a 2x2 grid.

      videotestsrc foreground-color=0x00ff0000 ! decklinkvideosink device-number=3 mode=1080p25

Capture 1080p25 from the second and third unit in the System, Playout a Test-Screen with colored Snow on the first and fourth unit (ie. the Connectors 1-4 of a Duo2 unit).

#### Device-Number-Mapping in Half-Duplex-Mode

The device-number to connector-mapping in half-duplex-mode is as follows for the Duo2

- `device-number=0` SDI1

- `device-number=1` SDI3

- `device-number=2` SDI2

- `device-number=3` SDI4

And for the Quad2

- `device-number=0` SDI1

- `device-number=1` SDI3

- `device-number=2` SDI5

- `device-number=3` SDI7

- `device-number=4` SDI2

- `device-number=5` SDI4

- `device-number=6` SDI6

- `device-number=7` SDI8

#### Full-Duplex-Mode:

When operating in full-duplex mode, two connectors of a unit are combined to a single device, performing extra processing with the second connection.

This mode is most useful for Playout. See `decklinkvideosink` . For Capturing the options are as follows:

When capturing from a duplex-unit, the secondary port outputs the captured image unchanged.

    3
    gst-launch-1.0 \
      decklinkvideosrc device-number=0 mode=1080p25 duplex-mode=full ! \
      autovideosink

When simultaneously capturing and playing out onto the same device, the secondary port outputs the played out video. Note, that this can also be achieved using half-duplex mode.

    gst-launch-1.0 \
      decklinkvideosrc device-number=0 mode=1080p25 duplex-mode=full ! \
      videoflip video-direction=vert ! \
      decklinkvideosink device-number=0 mode=1080p25 duplex-mode=full

Capturing Video on the primary port of device 0, output flipped version of the video on secondary port of the same device.

#### Device-Number-Mapping in Full-Duplex-Mode

The device-number to connector-mapping in full-duplex-mode is as follows for the Duo2

- `device-number=0` SDI1 primary, SDI2 secondary

- `device-number=1` SDI3 primaty, SDI4 secondary

And for the Quad2

- `device-number=0` SDI1 primary, SDI2 secondary

- `device-number=1` SDI3 primaty, SDI4 secondary

- `device-number=2` SDI5 primary, SDI6 secondary

- `device-number=3` SDI7 primary, SDI8 secondary

## Functions

## Types and Values

### struct GstDecklinkVideoSrc

    struct GstDecklinkVideoSrc;

## Property Details

### The `“buffer-size”` property

      “buffer-size”              guint

Size of internal buffer in number of video frames.

Flags: Read / Write

Allowed values: [1,G_MAXINT]

Default value: 5

### The `“connection”` property

      “connection”               GstDecklinkConnection

Video input connection to use.

Flags: Read / Write / Construct

Default value: Auto

### The `“device-number”` property

      “device-number”            gint

Output device instance to use.

Flags: Read / Write / Construct

Allowed values: >= 0

Default value: 0

### The `“mode”` property

      “mode”                     GstDecklinkModes

Video Mode to use for playback.

Flags: Read / Write / Construct

Default value: Automatic detection

### The `“video-format”` property

      “video-format”             GstDecklinkVideoFormat

Video format type to use for input (Only use auto for mode=auto).

Flags: Read / Write / Construct

Default value: Auto

### The `“timecode-format”` property

      “timecode-format”          GstDecklinkTimecodeFormat

Timecode format type to use for input.

Flags: Read / Write / Construct

Default value: bmdTimecodeRP188Any

### The `“drop-no-signal-frames”` property

      “drop-no-signal-frames”    gboolean

Drop frames that are marked as having no input signal.

Flags: Read / Write

Default value: FALSE

### The `“output-stream-time”` property

      “output-stream-time”       gboolean

Output stream time directly instead of translating to pipeline clock.

Flags: Read / Write

Default value: FALSE

### The `“skip-first-time”` property

      “skip-first-time”          guint64

Skip that much time of initial frames after starting.

Flags: Read / Write

Default value: 0

### The `“signal”` property

      “signal”                   gboolean

True if there is a valid input signal available.

Flags: Read

Default value: FALSE

### The `“hw-serial-number”` property

      “hw-serial-number”         gchar *

The serial number (hardware ID) of the Decklink card.

Flags: Read

Default value: NULL

### The `“output-cc”` property

      “output-cc”                gboolean

Extract and output CC as GstMeta (if present).

Flags: Read / Write

Default value: FALSE

### The `“duplex-mode”` property

      “duplex-mode”              GstDecklinkDuplexMode

Certain DeckLink devices such as the DeckLink Quad 2 and the DeckLink Duo 2 support configuration of the duplex mode of individual sub-devices.A sub-device configured as full-duplex will use two connectors, which allows simultaneous capture and playback, internal keying, and fill & key scenarios.A half-duplex sub-device will use a single connector as an individual capture or playback channel.

Flags: Read / Write / Construct

Default value: Half-Duplex
