<!--TITLE:H.264/AVC Video Decoder--> <!--H1:H.264/AVC Video Decoder--> {{This|products/directshow_filters/h_264_decoder.html}} High-quality DirectShow decoder for H.264/AVC video streams. ==Overview== * {{H.264/AVC Video Decoder DirectShow Filter: Download}} * {{Contact Support}} * {{Place Order!}} DirectShow decoder filter for H.264/AVC video streams. ===Why H.264?=== H.264/MPEG-4 Part 10 or AVC (Advanced Video Coding) is the latest motion compensation-based video compression technology available today. At only ''half the bandwidth of MPEG-2'', H.264 provides better video quality due to a deblocking filter that helps smooth the sharp edges between macroblocks. Because of this, H.264 is especially suited for ''HD video''. H.264 is used in: * HDTV broadcasting * Digital Cinema * CCTV (Close Circuit TV) and Video Surveillance * Web players and YouTube-like video sharing sites * Blue-ray optical discs {{Licensing: Codecs}} ==Features== * Supports Baseline profile (BP), Main profile (MP), Extended profile (XP) and High profile (HiP). * Multicore/Hyper Threading support. * MMX/SSE/SSE2/SSE3 ASM optimization. * CABAC/CAVLC. * I, P and B slices. * AVC-Intra support. * AVC1 file and byte stream formats support. * Field or frame pictures. * Color space convertions (YUY2, UYVY, YVYU, ARGB32, RGB32, RGB24, RGB565, RGB555, YV12, I420). <!--==Technical Specs== ===DirectShow Interfaces=== '''Filter Interfaces:''' IBaseFilter, IPersistStream, ISpecifyPropertyPages, IMLH264Decoder '''Input Pin Media Types:''' * ''majortype'': MEDIATYPE_Video, MEDIATYPE_MPEG2_PES * ''subtype'': MEDIASUBTYPE_AVC1 {31435641-0000-0010-8000-00AA00389B71}: AVC file format according to ISO/IEC 14496-15, used in QT and other files; MEDIASUBTYPE_H264ByteStream {8D2D71CB-243F-45E3-B2D8-5FD7967EC09B}: ITU-T Rec.
