DirectShow filter for encoding 8-bit 4:2:0 progressive or interlaced video frames in HEVC, H264 or MPEG-2 formats.
Overview
QuickSync Encoder is a DirectShow filter for encoding 8-bit 4:2:0 progressive or interlaced video frames in HEVC, H264 or MPEG-2 formats. Filter based on Intel® Media SDK with Intel QuickSync GPU support and hardware acceleration. Support for encoders depends on the type of Windows (32 or 64 bit), installed video driver (for hardware encoding) and input format (interlaced or progressive):
- H264 and MPEG-2, 32 and 64 bits: hardware and software
- HEVC 64 bits: hardware, software or GACC (the last two are for progressive frames only)
- HEVC 32 bits: only hardware encoding
The 32-bit and 64-bit software libraries and HEVC software/GACC plug-ins from the latest Intel Media SDK (2019R1) are included in the installer.
The output bitstreams are encoded as raw byte streams or MPEG-4 streams (with a prefix length word according to ISO/IEC 14496-15 and ISO/IEC 14496-17) depending on the connection media type. The list of supported input/output mediatypes and interfaces can be found in \Idl\QSEncoder.idl file in the filter installation folder.
NOTE. The HEVC software encoder has a very large latency: the first encoded bitstream will be ready only after loading about 2 x number of CPUs input frames into the filter.
Features
