Struct FfmpegTask 

pub struct FfmpegTask { /* private fields */ }

FFmpeg task builder for running host-side transcoding.

Example

use vtx_sdk::prelude::*;

fn handle_video(vid: String) -> VtxResult<Response> {
    FfmpegTask::new("mini", vid)
        .option("ss", "10")
        .option("t", "30")
        .execute()
}

Implementations

impl FfmpegTask

pub fn new(profile: impl Into<String>, input_id: impl Into<String>) -> Self

Create a new FFmpeg task.

• profile: Target FFmpeg profile (e.g., “mini”, “remux”, “thumbnail”).
• input_id: Input resource ID (UUID) or “pipe:0”.

pub fn new_pipe(profile: impl Into<String>) -> Self

Create a task that uses stdin as input (input_id = "pipe:0").

pub fn option(self, key: impl Into<String>, value: impl Into<String>) -> Self

Add a key/value FFmpeg option (encoded as -key=value).

pub fn flag(self, key: impl Into<String>) -> Self

Add a flag-style FFmpeg option (encoded as -key).

pub fn options<I, K, V>(self, options: I) -> Self

where I: IntoIterator<Item = (K, V)>, K: Into<String>, V: Into<String>,

Add a batch of key/value options.

pub fn format(self, format: &str) -> Self

Helper: Set output format (equivalent to -f=format).

pub fn seek(self, start: &str, duration: Option<&str>) -> Self

Helper: Set seek window (equivalent to -ss + optional -t).

pub fn build(self) -> TranscodeProfile

Builds the TranscodeProfile payload.

pub fn execute_buffer(self) -> VtxResult<Buffer>

Execute and return the stdout pipe buffer.

This method performs an IO operation.

pub fn execute(self) -> VtxResult<HttpResponse>

Execute and return an HTTP response (200 with stdout pipe body).

This method performs an IO operation.
