Deinterlacing using based on fragment shaders.

Examples

 gst-launch-1.0 videotestsrc ! glupload ! gldeinterlace ! glimagesink

FBO (Frame Buffer Object) and GLSL (OpenGL Shading Language) are required.

Properties

drop-orphans

“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


fields

“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 (0)


ignore-obscure

“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


locking

“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 : none (0)


method

“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 appropriate 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.
  • yadif YADIF Adaptive.

Flags : Read / Write

Default value : linear (4)


mode

“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 (0)


tff

“tff” GstDeinterlaceFieldLayout *

Deinterlace top field first

Flags : Read / Write

Default value : auto (0)


Named constants

GstDeinterlaceFieldLayout

Members

auto (0) – Auto detection
tff (1) – Top field first
bff (2) – Bottom field first

GstDeinterlaceFields

Members

all (0) – All fields
top (1) – Top fields only
bottom (2) – Bottom fields only
auto (3) – Automatically detect

GstDeinterlaceLocking

Members

none (0) – No pattern locking
auto (1) – Choose passive/active locking depending on whether upstream is live
active (2) – Block until pattern-locked. Use accurate timestamp interpolation within a pattern repeat.
passive (3) – Do not block. Use naïve timestamp adjustment until pattern-locked based on state history.
