## Description

Split data to multiple pads. Branching the data flow is useful when e.g. capturing a video where the video is shown on the screen and also encoded and written to a file. Another example is playing music and hooking up a visualisation module.

One needs to use separate queue elements (or a multiqueue) in each branch to provide separate threads for each branch. Otherwise a blocked dataflow in one branch would stall the other branches.

### Example launch line

    1
    gst-launch filesrc location=song.ogg ! decodebin2 ! tee name=t ! queue ! autoaudiosink t. ! queue ! audioconvert ! goom ! ffmpegcolorspace ! autovideosink

Play a song.ogg from local dir and render visualisations using the goom element.

## Details

### struct GstTee

    struct GstTee;

Opaque GstTee data structure.

### enum GstTeePullMode

    typedef enum {
      GST_TEE_PULL_MODE_NEVER,
      GST_TEE_PULL_MODE_SINGLE,
    } GstTeePullMode;

The different ways that tee can behave in pull mode. `TEE_PULL_MODE_NEVER` disables pull mode.

`GST_TEE_PULL_MODE_NEVER` | Never activate in pull mode.
`GST_TEE_PULL_MODE_SINGLE` | Only one src pad can be active in pull mode.
