From 9042b4564de5477b18e680c7dce13b587a681dd9 Mon Sep 17 00:00:00 2001 From: Mathias Agopian Date: Mon, 26 Oct 2009 20:12:37 -0700 Subject: fix [2143798] Need to figure out how to do video Use EGLImageKHR instead of copybit directly. We now have the basis to use streaming YUV textures (well, in fact we already are). When/if we use the GPU instead of the MDP we'll need to make sure it supports the appropriate YUV format. Also make sure we compile if EGL_ANDROID_image_native_buffer is not supported --- libs/surfaceflinger/LayerBuffer.cpp | 143 ++++++------------------------------ 1 file changed, 22 insertions(+), 121 deletions(-) (limited to 'libs/surfaceflinger/LayerBuffer.cpp') diff --git a/libs/surfaceflinger/LayerBuffer.cpp b/libs/surfaceflinger/LayerBuffer.cpp index 7e27a02be819..6590503d31f1 100644 --- a/libs/surfaceflinger/LayerBuffer.cpp +++ b/libs/surfaceflinger/LayerBuffer.cpp @@ -339,12 +339,6 @@ LayerBuffer::BufferSource::BufferSource(LayerBuffer& layer, mLayer.setNeedsBlending((info.h_alpha - info.l_alpha) > 0); mBufferSize = info.getScanlineSize(buffers.hor_stride)*buffers.ver_stride; mLayer.forceVisibilityTransaction(); - - hw_module_t const* module; - mBlitEngine = NULL; - if (hw_get_module(COPYBIT_HARDWARE_MODULE_ID, &module) == 0) { - copybit_open(module, &mBlitEngine); - } } LayerBuffer::BufferSource::~BufferSource() @@ -352,8 +346,9 @@ LayerBuffer::BufferSource::~BufferSource() if (mTexture.name != -1U) { glDeleteTextures(1, &mTexture.name); } - if (mBlitEngine) { - copybit_close(mBlitEngine); + if (mTexture.image != EGL_NO_IMAGE_KHR) { + EGLDisplay dpy(mLayer.mFlinger->graphicPlane(0).getEGLDisplay()); + eglDestroyImageKHR(dpy, mTexture.image); } } @@ -421,122 +416,28 @@ void LayerBuffer::BufferSource::onDraw(const Region& clip) const status_t err = NO_ERROR; NativeBuffer src(ourBuffer->getBuffer()); const Rect transformedBounds(mLayer.getTransformedBounds()); - copybit_device_t* copybit = mBlitEngine; - - if (copybit) { - const int src_width = src.crop.r - src.crop.l; - const int src_height = src.crop.b - src.crop.t; - int W = transformedBounds.width(); - int H = transformedBounds.height(); - if (mLayer.getOrientation() & Transform::ROT_90) { - int t(W); W=H; H=t; - } - -#ifdef EGL_ANDROID_get_render_buffer - EGLDisplay dpy = eglGetCurrentDisplay(); - EGLSurface draw = eglGetCurrentSurface(EGL_DRAW); - EGLClientBuffer clientBuf = eglGetRenderBufferANDROID(dpy, draw); - android_native_buffer_t* nb = (android_native_buffer_t*)clientBuf; - if (nb == 0) { - err = BAD_VALUE; - } else { - copybit_image_t dst; - dst.w = nb->width; - dst.h = nb->height; - dst.format = nb->format; - dst.base = NULL; // unused by copybit on msm7k - dst.handle = (native_handle_t *)nb->handle; - - /* With LayerBuffer, it is likely that we'll have to rescale the - * surface, because this is often used for video playback or - * camera-preview.
