示例1: android_hardware_Camera_setHasPreviewCallback
static void android_hardware_Camera_setHasPreviewCallback(JNIEnv *env, jobject thiz, jboolean installed, jboolean manualBuffer)
{
LOGV("setHasPreviewCallback: installed:%d, manualBuffer:%d", (int)installed, (int)manualBuffer);
// Important: Only install preview_callback if the Java code has called
// setPreviewCallback() with a non-null value, otherwise we'd pay to memcpy
// each preview frame for nothing.
JNICameraContext* context;
sp<Camera> camera = get_native_camera(env, thiz, &context);
if (camera == 0) return;
// setCallbackMode will take care of setting the context flags and calling
// camera->setPreviewCallbackFlags within a mutex for us.
context->setCallbackMode(env, installed, manualBuffer);
}示例2: android_hardware_Camera_setPreviewCallbackSurface
static void android_hardware_Camera_setPreviewCallbackSurface(JNIEnv *env,
jobject thiz, jobject jSurface)
{
ALOGV("setPreviewCallbackSurface");
JNICameraContext* context;
sp<Camera> camera = get_native_camera(env, thiz, &context);
if (camera == 0) return;
sp<IGraphicBufferProducer> gbp;
sp<Surface> surface;
if (jSurface) {
surface = android_view_Surface_getSurface(env, jSurface);
if (surface != NULL) {
gbp = surface->getIGraphicBufferProducer();
}
}
// Clear out normal preview callbacks
context->setCallbackMode(env, false, false);
// Then set up callback surface
if (camera->setPreviewCallbackTarget(gbp) != NO_ERROR) {
jniThrowException(env, "java/io/IOException", "setPreviewCallbackTarget failed");
}
