soy capaz de reproducir un vídeo Transmisión con conexión de servidor HTTP en un SurfaceView
. Y yo estaba creando ContextMenu
para grabar el video mediante la adición de elementos de menú StartRecording y StopRecording. Pero soy capaz de grabar una cámara de vídeo llamando mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
Cómo grabar video en tiempo real?
Aquí quiero fijar como fuente de video streaming de vídeo Fuente. ¿Hay alguna posibilidad de hacer esto?
Pero quiero grabar el streaming de vídeo mientras se está reproduciendo. ¿Puedes decirme cómo grabar mientras suena?
¿Podría proporcionarnos algún código de muestra para este problema?
Mi código de ejemplo se muestra a continuación:
