Type Alias PostDecodeHook 

pub type PostDecodeHook = Arc<dyn Fn(&DecodedStreamInfo) -> Option<String> + Sync + Send>;

Hook invoked once per feed when the decoded stream’s caps are known.

The hook receives a DecodedStreamInfo describing the decoded stream and returns an optional GStreamer element name to insert between the decoder and the color-space converter. Returning None means no additional element is needed.

Example

On Jetson, hardware decoders output video/x-raw(memory:NVMM) — GPU-mapped buffers that the standard videoconvert cannot accept. A post-decode hook can bridge this:

use std::sync::Arc;
use nv_media::PostDecodeHook;

let hook: PostDecodeHook = Arc::new(|info| {
    if info.memory_type.as_deref() == Some("NVMM") {
        Some("nvvidconv".into())
    } else {
        None
    }
});
