Intel H.264 Video Encoder MFT is ignoring texture synchronization too

Some time ago I wrote about a bug in AMD’s H.264 Video Encoder MFT, where implementation fails to synchronize access to Direct3D 11 texture. So Intel’s implementation has exactly the same problem. Intel® Quick Sync Video H.264 Encoder MFT processes input textures/frames without acquiring synchroization and can lose actual content. It is pretty hard to reproduce…

Minefields of Intel Media SDK

When it comes to vendor specific SDK for hardware assisted video encoding, Intel Media SDK is perhaps the oldest one among current vendors: Intel, NVIDIA, AMD. And also surprisingly the worst one. All three vendors are offering their SDKs for really close capabilities, however the kits are designed and structured differently. If NVIDIA and AMD…

AMD’s three ways to spell “enhancement”

From AMD AMF SDK documentation, AMF_Video_Encode_API.pdf: The typos are not a big deal for development, even though the symbol with the typo is a shortcut to a string with the same typo: #define AMF_VIDEO_ENCODER_NUM_TEMPORAL_ENHANCMENT_LAYERS L”NumOfTemporalEnhancmentLayers” The SDK offers a good frontend to AMD VCE hardware encoders, however there are a few unfortunate problems: documentation is…
