Function Documentation

Java_com_tagtraum_ffsampledsp_FFStreamInputStream_close()

JNIEXPORT void JNICALL Java_com_tagtraum_ffsampledsp_FFStreamInputStream_close	(	JNIEnv *	env,
		jobject	stream,
		jlong	aio_pointer )

Frees all resources associated with the given FFAudioIO.

Parameters

env	JNIEnv
stream	FFStreamInputStream instance
aio_pointer	pointer to FFAudioIO

Definition at line 259 of file FFStreamInputStream.c.

Java_com_tagtraum_ffsampledsp_FFStreamInputStream_fillNativeBuffer()

JNIEXPORT void JNICALL Java_com_tagtraum_ffsampledsp_FFStreamInputStream_fillNativeBuffer	(	JNIEnv *	env,
		jobject	stream,
		jlong	aio_pointer )

Fills the java-side buffer (allocated via Java code) with fresh audio data.

Parameters

env	JNIEnv
stream	FFStreamInputStream instance
aio_pointer	pointer to the FFAudioIO created when opening the file

Definition at line 132 of file FFStreamInputStream.c.

Java_com_tagtraum_ffsampledsp_FFStreamInputStream_initIDs()

JNIEXPORT void JNICALL Java_com_tagtraum_ffsampledsp_FFStreamInputStream_initIDs	(	JNIEnv *	env,
		jclass	streamClass )

Init static method and field ids for Java methods/fields.

Called exactly once from the static initializer of FFStreamInputStream. Because the JVM serializes class initialization, the ids are guaranteed to be set before any thread can call into native code with a stream instance.

Parameters

env	JNIEnv
streamClass	FFStreamInputStream class

Definition at line 43 of file FFStreamInputStream.c.

Java_com_tagtraum_ffsampledsp_FFStreamInputStream_open()

JNIEXPORT jlong JNICALL Java_com_tagtraum_ffsampledsp_FFStreamInputStream_open	(	JNIEnv *	env,
		jobject	stream,
		jint	streamIndex )

Creates the FFAudioIO, custom AVIOContext etc for reading data from the stream.

Parameters

env	JNIEnv
stream	calling FFStreamInputStream instance

Returns

pointer to the created FFAudioIO
