FFmpeg를 사용하는 비디오를 jni의 OpenGL ES 텍스처로 변환하려고합니다.하지만 얻은 모든 것은 검은 색 텍스처입니다. OpenGL을 glGetError()
과 함께 출력했지만 오류는 없습니다.FFmpeg 프레임을 OpenGL ES 텍스처로 변환
여기 내 코드입니다 : 나는 자바 비트 맵 pFrameRGB 변경에 성공했다

,하지만 난 그냥 C 코드의 텍스처로 변경하고 싶습니다.
편집 1 텍스쳐 ID를 출력했습니다. 0입니다. 텍스처 ID가 0일까요? 내 코드 을 변경했지만 항상 0입니다.
편집 2 텍스처 디스플레이이지만 엉망입니다.
