示例1: TestTextureClientYCbCr
// Same as above, for YCbCr surfaces
void TestTextureClientYCbCr(TextureClient* client, PlanarYCbCrData& ycbcrData) {
client->Lock(OpenMode::OPEN_READ_WRITE);
UpdateYCbCrTextureClient(client, ycbcrData);
client->Unlock();
// client serialization
SurfaceDescriptor descriptor;
ASSERT_TRUE(client->ToSurfaceDescriptor(descriptor));
ASSERT_EQ(descriptor.type(), SurfaceDescriptor::TSurfaceDescriptorBuffer);
auto bufferDesc = descriptor.get_SurfaceDescriptorBuffer();
ASSERT_EQ(bufferDesc.desc().type(), BufferDescriptor::TYCbCrDescriptor);
auto ycbcrDesc = bufferDesc.desc().get_YCbCrDescriptor();
ASSERT_EQ(ycbcrDesc.ySize(), ycbcrData.mYSize);
ASSERT_EQ(ycbcrDesc.cbCrSize(), ycbcrData.mCbCrSize);
ASSERT_EQ(ycbcrDesc.stereoMode(), ycbcrData.mStereoMode);
// host deserialization
RefPtr<TextureHost> textureHost = CreateBackendIndependentTextureHost(descriptor, nullptr,
client->GetFlags());
RefPtr<BufferTextureHost> host = static_cast<BufferTextureHost*>(textureHost.get());
ASSERT_TRUE(host.get() != nullptr);

// host read
if (host->Lock()) {
// This will work iff the compositor is not BasicCompositor
ASSERT_EQ(host->GetFormat(), mozilla::gfx::SurfaceFormat::YUV);
host->Unlock();
