Function Documentation

Java_com_tagtraum_ffsampledsp_FFCodecInputStream_initIDs()

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

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

Called exactly once from the static initializer of FFCodecInputStream. 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	FFCodecInputStream class

Java_com_tagtraum_ffsampledsp_FFCodecInputStream_open()

JNIEXPORT jlong JNICALL Java_com_tagtraum_ffsampledsp_FFCodecInputStream_open	(	JNIEnv *	env,
		jobject	object,
		jobject	target_format,
		jlong	aio_pointer )

Re-configures SwrContext and Encoder to match the provided target_format.

Parameters

env	JNIEnv
object	stream instance this call stems from, i.e. a FFCodecInputStream
target_format	target AudioFormat
aio_pointer	Pointer to the FFAudioIO struct of the FFNativePeerInputStream that opened the file/stream

Returns

pointer to the FFAudioIO struct that was given as parameter
