Pull Request Overview
This PR fixes a crash in the AV1 encoder and improves error handling across video codec encoders. The changes focus on preventing null pointer crashes, enhancing debugging capabilities, and ensuring platform compatibility.
Key changes include:
- Added null pointer checks to VP9 and AV1 encoders to prevent crashes when I420 buffer is missing
- Enhanced Vulkan graphics device error logging for better debugging
- Added platform-specific guards for CUDA code to improve portability

Missing space after 'timeout.' - should be 'timeout. ' to properly separate from the next line.

This pull request introduces several improvements and bug fixes related to video codec encoders and Vulkan graphics device handling. The main focus is on improving error handling in the VP9 and AV1 encoder code, enhancing Vulkan device logging, and ensuring platform-specific code is properly guarded.
Codec Encoder Robustness and Error Handling:
libvpx_vp9_encoder.ccandlibaom_av1_encoder.ccto prevent crashes if the I420 buffer is missing, returning failure codes or empty values as appropriate. [1] [2]build_libwebrtc_android.sh) to apply new patches for VP9 and AV1 encoders, ensuring these error checks are included during the build process.Vulkan Graphics Device Improvements:
VulkanGraphicsDevice.cppfor failed texture access and synchronization timeouts, making debugging easier when Vulkan resource operations fail. [1] [2]<chrono>header inVulkanGraphicsDevice.cppto support time-based operations.Platform-Specific Code Guarding:
GpuMemoryBuffer.cppwith#if CUDA_PLATFORMto ensure it only compiles on supported platforms, improving portability and preventing build errors.
