Example

package myfancypkg

import (
    "github.com/xaionaro-go/libsrt"
    "github.com/xaionaro-go/libsrt/sockopt"
    "github.com/xaionaro-go/libsrt/extras/xastiav"
)

func myFancyFunc() {
    [...]

    // extracting the file descriptor from a go-astiav's structure:

    sockS := xastiav.GetFDFromFormatContext(formatCtx)

    // manipulating the SRT socket

    s := libsrt.SocketFromC(sockC)
    err := s.Setsockflag(sockopt.LATENCY, libsrt.BlobInt(5000000)) // 5 seconds
    if err != nil {
        return fmt.Errorf("unable to set latency to 5 seconds: %w", libsrt.Getlasterror()) // yes, this is how libsrt works, unfortunately, you need to ask for an error code in a thread-unsafe manner.
    }

    [...]
