//! Stream-based I/O pipeline.
|
|
//!
|
|
//! All formats are streams. Two URLs, left reads, right writes:
|
|
//!
|
|
//! ```text
|
|
//! freemkv disc:// mkv://Dune.mkv
|
|
//! freemkv m2ts://Dune.m2ts mkv://Dune.mkv
|
|
//! freemkv disc:// network://10.0.0.1:9000
|
|
//! freemkv disc:// stdio://
|
|
//! freemkv stdio:// mkv://Dune.mkv
|
|
//! ```
|
|
//!
|
|
//! Streams implement `IOStream` for uniform handling:
|
|
//!
|
|
//! ```text
|
|
//! let mut input = open_input("disc://", &opts)?;
|
|
//! let mut output = open_output("mkv://Dune.mkv", input.info())?;
|
|
//! io::copy(&mut *input, &mut *output)?;
|
|
//! output.finish()?;
|
|
//! ```
