Detailed Description

Represents a single filter pass in the scaling graph.

Each filter will read from some previous pass's output, and write to a buffer associated with the pass (or into the final output image).

run

sws_filter_run_t SwsPass::run

Filter main execution function.

Called from multiple threads, with the granularity dictated by slice_h. Individual slices sent to run are always equal to (or smaller than, for the last slice) slice_h.

input

const SwsPass* SwsPass::input

Filter input.

This pass's output will be resolved to form this pass's. input. If NULL, the original input image is used.

Definition at line 86 of file graph.h.

Referenced by ff_sws_graph_add_pass(), and sws_graph_worker().

output

SwsImg SwsPass::output

Filter output buffer.

Allocated on demand and freed automatically.

Definition at line 91 of file graph.h.

Referenced by ff_sws_graph_add_pass(), ff_sws_graph_free(), pass_alloc_output(), and sws_graph_worker().

setup

void(* SwsPass::setup) (const SwsImg *out, const SwsImg *in, const SwsPass *pass)

Called once from the main thread before running the filter.

Optional. out and in always point to the main image input/output, regardless of input and output fields.

Definition at line 98 of file graph.h.

Referenced by adapt_colors(), ff_sws_graph_run(), and init_legacy_subpass().

free

void(* SwsPass::free) (void *priv)

Optional private state and associated free() function.

Definition at line 103 of file graph.h.
