Another problem (bug) with Microsoft Media Foundation MPEG-4 Media Source H.265/HEVC handler is that it ignores conformance_window_flagflag and values from H.265’s seq_parameter_set_rbsp (see H.265 spec, F.7.3.2.2.1 General sequence parameter set RBSP syntax). The problem might or might not be limited to fragmented MP4 variants. It is overall questionable whether it has been a good idea…
MPEG-4 Media Foundation Source stubbornly keeps marking a second video sample with a MFSampleExtension_CleanPoint flag even though nothing suggests that the video frame is an IDR frame. The actual video frame is a P frame both in terms of MP4 box formatting and contained NAL units (the video is in fact an “infinite GOP” flavor…
Microsoft released new Windows 10 update and again there is a new tsunami approaching. Media Foundation H.265 decoder: there is no longer “preliminary documentation” notice in MSDN article. The decoder is a substandard quality software item but it covers more or less what it has to. In particular, it indeed backs H.265 video playback including…
H.265 / HEVC Video Decoder Media Foundation has been around for a while, but using Media Foundation overall one step off straightforward basic paths is like walking a minefield. A twenty-liner below hits memory access violation inside IMFTransform::GetInputStreamInfo “Exception thrown at 0x6D1E71E7 (hevcdecoder.dll) in MfHevcDecoder01.exe: 0xC0000005: Access violation reading location 0x00000000.”: #include “stdafx.h” #include <mfapi.h>…
It should be good news for those interested in hardware assisted video encoding as AMD extends offering in their new hardware and offers H.265 encoder in already well-known form factor: as a Microsoft Media Foundation Transform “AMDh265Encoder”: # System * Version: 10.0.14393, Windows 10, VER_SUITE_SINGLEUSERTS, VER_NT_WORKSTATION * Product: PRODUCT_PROFESSIONAL […] # Display Devices * AMD…
Some time ago there were some pictures explaining performance and other properties of software H.264 encoder (x264). At this time, it is a turn of hardware H.264 encoders and more to that, two of them and side by side. Both encoders are nothing new: Intel® Quick Sync Video H.264 Encoder and NVIDIA H.264 Encoder already…
