Getting Started

• Visual Studio® solutions can be found in the \vivecinema directory.

Run the Program

• Put videos in \vivecinema\bin\videos directory or edit \vivecinema\bin\assets\vivecinema.xml to specify video directories.
• Refer Viveport Vive Cinema for more details.

Balai 3D/VR

Balai 3D/VR is a rendering framework we created for easily building simple 3D/VR applications. You may find some samples in \samples directory.

Known Issues

• Few memleak reports when app closing (VS2012).
• Leveraging VS2012 non C++ standard std::async() for asynchronization.
• Potential crash on 32-bit build for huge videos(e.g. 4096x4096, 8192x8192). Always use 64-bit build if possible.
• AMD AMF GPU accelerated video decoder is still testing. Switch back to CPU decoder (Press F4) if any problem occurs.
• Cubemap/EAC may experience visible seams, tweak 'padding' settings to minimize it. (refer vivecinema.xml for more details)
