vlcj로 youtube 비디오를 재생하는 데 문제가 있습니다. 지난 주까지 모든 일이 진행되고있었습니다. 나는 mediaPlayer.playMedia ("http://www.youtube.com/watch?v=1t8fl96HPQI")를 호출하고 있었지만 정상적으로 작동했지만 더 이상 작동하지 않았습니다. 그것은 전혀 오류를 발생시키지 않습니다. 로컬 파일 및 기타 온라인 스트리밍 URL은 재생할 수 있지만 YouTube 동영상은 재생할 수 없습니다.vlcj가 더 이상 작동하지 않는 youtube 비디오 재생
이것은 내가 사용하고있는 코드입니다.
mediaPlayer.setPlaySubItems(true); // <--- This is very important for YouTube media
아래 코드는 모든 하위 항목을 가져옵니다 YouTube 동영상의 경우 (기본적으로 자사의 준비 예)

/**
* A minimal YouTube player.
* <p>
* The URL/MRL must be in the following format:
* <pre>
* http://www.youtube.com/watch?v=000000
* </pre>
* The only thing that makes this different from a 'regular' media player
* application is the following piece of code:
* <pre>
* mediaPlayer.setPlaySubItems(true); // <--- This is very important for YouTube media
* </pre>
* Note that it is also possible to programmatically play the sub-item in
* response to events - this is slightly more complex but more flexible.
* <p>
* The YouTube web page format changes from time to time. This means that the
* lua scripts that vlc provides to parse the YouTube web pages when looking
* for the media to stream may not work. If you get errors, especially errors
* alluding to malformed urls, then you may need to update your vlc version to
* get newer lua scripts.

당신은이 코드를합니다. 이 일하는

하지만 지금은 인쇄이 같은 하나 개의 하위 항목 :
[http://www.youtube.com/get_video_info?video_id=1t8fl96HPQI & 엘 = detailpage]의 실제 URL이 아닙니다
비디오와 나는 그것이 왜 놀지 않는지 생각한다.
왜 이런 일이 일어나는 지 알고 싶습니다. Google이 자신의 YouTube 페이지 형식으로 무엇인가를 변경 했습니까?
내가 찾은 튜토리얼에서 제안한 것처럼 vlc youtube.lua 파일을 업그레이드하려고했지만 운이 없었습니다.
또한 vlc에서 동일한 링크를 사용할 때 제대로 작동합니다.
사양 :
우분투 12.0.4 64 비트
VLC 미디어 플레이어 2.0.5 Twoflower
vlcj 미리 2.2.0
감사
