blend_video

void(* vlc_filter_operations::blend_video) (filter_t *, picture_t *, const picture_t *, int, int, int)

Blend a subpicture onto a picture (video blending)

Referenced by filter_Blend().

change_viewpoint

void(* vlc_filter_operations::change_viewpoint) (filter_t *, const vlc_viewpoint_t *)

Change viewpoint.

Pass a new viewpoint to audio filters. Filters like the spatialaudio one used for Ambisonics rendering will change its output according to this viewpoint.

Referenced by filter_ChangeViewpoint().

close

void(* vlc_filter_operations::close) (filter_t *)

Close the filter and release its resources.

Referenced by vlc_filter_UnloadModule().

drain_audio

block_t *(* vlc_filter_operations::drain_audio) (filter_t *)

Drain (audio filter)

Referenced by filter_DrainAudio(), and vlc_audio_meter_AddPlugin().

filter_audio

block_t *(* vlc_filter_operations::filter_audio) (filter_t *, block_t *)

Filter an audio block (audio filter)

Referenced by aout_filter_Create(), aout_FiltersPipelinePlay(), and vlc_audio_meter_Process().

filter_sub

subpicture_t *(* vlc_filter_operations::filter_sub) (filter_t *, subpicture_t *)

Filter a subpicture (sub filter)

Referenced by SubFilter().

filter_video

picture_t *(* vlc_filter_operations::filter_video) (filter_t *, picture_t *)

Filter a picture (video filter)

Referenced by FilterSingleChainedFilter(), ImageConvert(), ImageRead(), ImageWrite(), and SpuRenderRegion().

flush

void(* vlc_filter_operations::flush) (filter_t *)

Flush.

Flush (i.e. discard) any internal buffer in a video or audio filter.

Referenced by filter_Flush().

render

subpicture_region_t *(* vlc_filter_operations::render) (filter_t *, const subpicture_region_t *, const vlc_fourcc_t *)

Render text (text renderer)

Returns

a picture-based region or NULL

Referenced by SpuRenderText().

source_sub

subpicture_t *(* vlc_filter_operations::source_sub) (filter_t *, vlc_tick_t)

Generate a subpicture (sub source)

Referenced by SubSourceGenerate().

video_mouse

int(* vlc_filter_operations::video_mouse) (filter_t *, struct vlc_mouse_t *, const struct vlc_mouse_t *p_old)

Filter mouse state (video filter).

If non-NULL, you must convert from output to input formats:

• If VLC_SUCCESS is returned, the mouse state is propagated.
• Otherwise, the mouse change is not propagated. If NULL, the mouse state is considered unchanged and will be propagated.
