Implemented Interfaces

GstDeinterlace implements GstChildProxy.

Description

deinterlace deinterlaces interlaced video frames to progressive video frames. For this different algorithms can be selected which will be described later.

Example launch line

1
 
gst-launch-1.0 -v filesrc location=/path/to/file ! decodebin ! videoconvert ! deinterlace ! videoconvert ! autovideosink
This pipeline deinterlaces a video file with the default deinterlacing options.

Property Details

The “fields” property

  “fields”                   GstDeinterlaceFields

This selects which fields should be output. If "all" is selected the output framerate will be double.

Flags: Read / Write

Default value: All fields

The “method” property

  “method”                   GstDeinterlaceMethods

Selects the different deinterlacing algorithms that can be used. These provide different quality and CPU usage.

Some methods provide parameters which can be set by getting the "method" child via the GstChildProxy interface and setting the appropiate properties on it.

  • tomsmocomp Motion Adaptive: Motion Search

  • greedyh Motion Adaptive: Advanced Detection

  • greedyl Motion Adaptive: Simple Detection

  • vfir Blur vertical

  • linear Linear interpolation

  • linearblend Linear interpolation in time domain. Any motion causes significant ghosting, so this method should not be used.

  • scalerbob Double lines

  • weave Weave. Bad quality, do not use.

  • weavetff Progressive: Top Field First. Bad quality, do not use.

  • weavebff Progressive: Bottom Field First. Bad quality, do not use.

Flags: Read / Write

Default value: Linear

The “mode” property

  “mode”                     GstDeinterlaceModes

This selects whether the deinterlacing methods should always be applied or if they should only be applied on content that has the "interlaced" flag on the caps.

Flags: Read / Write

Default value: Auto detection (best effort)

The “tff” property

  “tff”                      GstDeinterlaceFieldLayout

Deinterlace top field first.

Flags: Read / Write

Default value: Auto detection

The “drop-orphans” property

  “drop-orphans”             gboolean

This selects whether to drop orphan fields at the beginning of telecine patterns in active locking mode.

Flags: Read / Write

Default value: TRUE

The “ignore-obscure” property

  “ignore-obscure”           gboolean

This selects whether to ignore obscure/rare telecine patterns. NTSC 2:3 pulldown variants are the only really common patterns.

Flags: Read / Write

Default value: TRUE

The “locking” property

  “locking”                  GstDeinterlaceLocking

This selects which approach to pattern locking is used which affects processing latency and accuracy of timestamp adjustment for telecine streams.

Flags: Read / Write

Default value: No pattern locking
