# goTS (Go Transport Streams)

gots (Go Transport Streams) is a library for working with MPEG transport streams. It provides abstractions for reading packet information and program specific information (psi)

## Code of Conduct

## Examples

This is a simple example that extracts all PIDs from a ts file and prints them. [CLI example parser can be found here](cli/parsefile.go)

```go

func main() {

	pidSet := make(map[uint16]bool, 5)

	filename := "./scenario1.ts"

	file, err := os.Open(filename)

	if err == nil {

		pkt := make([]byte, packet.PacketSize)

		for read, err := file.Read(pkt); read > 0 && err == nil; read, err = file.Read(pkt) {

                        if err != nil {

                                println(err)

                                return

                        }

			pid, err := packet.Pid(pkt)

			if err != nil {

				println(err)

				continue

			}

			pidSet[pid] = true

		}

        	for v := range pidSet {

	        	fmt.Printf("Found pid %d\n", v)

	        }

	} else {

		fmt.Printf("Unable to open file [%s] due to [%s]\n", filename, err.Error())

}

```
