QuickSync Decoder


DirectShow filter for decoding 8-bit 4:2:0 progressive or interlaced video frames encoded in H264 format.

Overview


QuickSync Decoder is a DirectShow filter for decoding H.264/AVC video streams. Filter based on IntelĀ® Media SDK with Intel QuickSync GPU support and hardware acceleration.

The 32-bit and 64-bit software libraries from the latest Intel Media SDK (2019R1) are included in the installer.

Features

  • Supports hardware and software decoding of 8 bit 4:2:0 H264/AVC streams.
  • GPU/Multicore/Hyper Threading support.
  • SSE/SSE2/SSE3/AVX ASM color conversion optimization.
  • Supports AVC1 file and byte stream formats.
  • Progressive or interlaced frames.
Specifications and description of user interfaces can be found in the .idl file in the \Idl folder of the filter installation directory.

Known Issues

  • Enhanced Video Renderer problem.
    We have found that when running AVObjects QuickSync Encoder/Decoder with hardware acceleration and Enhanced Video Renderer, the Intel Media SDK methods quite often return the MFX_ERR_DEVICE_FAILED error. As a result, encoding/decoding must be stopped and restarted (with possible side effects such as loss of memory and resources) and there will be breaks in the video. Many MFX_WRN_DEVICE_BUSY warnings may also be returned, causing encoding/decoding to hang.
    The problem occurs on 12th Gen Intel Core Processors (tested on i3-1215u and i9-12900HK) and may also occur on 11th to 13th Gen Intel Core processors. We recommend replacing Enhanced Video Renderer with Video Renderer or Video Mixing Renderer when using hardware acceleration in AVObjects QSEncoder/QSDecoder on 12th Gen Intel Core processors. Let us know if this happens on other processors.
