Bluray의 M4TS 파일에서의 audio 인식 문제

[Jones]

안녕하세요?

Bluray의 M4TS 형태로 만들어진 AV 파일을 KMplayer에서 재생하니, 동작이 원활히 잘 되는데, 문제는 sound track 중에서 DTS-HD, DTS 방식을 인식하지 못하고, AC-3 방식만을 인식합니다.

즉, 그 파일에 들어있는 sound track이 총 5~6개인데, AC-3 두가지만 인식해서 이 두가지 사이에서만 전환이 가능합니다. 참고로 M4TS 파일 내의 PMT 내용은 아래와 같습니다.(제가 만든 허접한 툴로 분석한 거라...보시기가 어려울 수도...^^;)

KMplayer에서 M4TS 파일을 만날 경우, 어떠한 방식으로 audio type을 detect하시는지 알려주실 수 있으신지요? DTS-HD, DTS 방식을 가능하게 하려면, PMT 부분에 특별한 descriptor를 붙이면 가능한지...등등의 방법을 알려주시면 감사드리겠읍니다.

마지막으로 이렇게 좋은 player를 만들어 주셔서 참 감사합니다.

MediaInfo를 한 번 사용해 보시는건 어떨까요.

한데, KMplayer에서 화면 왼쪽 하단의 [AC-3][5.1CH] 부분을 클릭하면, 선택 가능한 audio list가 나오는데, AC-3 방식의 두가지 sound track만 리스트 됩니다. DTS-HD 또는 DTS 사운드 트랙을 선택하려면 어떻게 해야 하는지요?

감사합니다.
