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…
This is nice. One of the users submitted Media Foundation capture capability printout (here it goes exactly), with an interesting Media Foundation source: FaceRig Virtual Camera. Media Foundation API is not so friendly for extensibility, and not so popular overall, so virtual device there is an interesting thing. FaceRig is a program enabling anyone with…
Just like with DirectShow video capture capability information, it is helpful to unerstand what Medfia Foudnation video capture offering is exactly. Specifically: Video and audio sources available with MFEnumDeviceSources and MFCreateDeviceSource Source attributes, streams, media types DirectShow compatible representations H.264 realated attributes in media types might be not so obvious and device might report too…
Media Foundation as video capture API is inflexible. At Microsoft – besides standard Media Foundation problems of backward compatibility, availability of developer tools and overall awkwardness – they decided to no longer offer video capture extensibility with Media Foundation. Be happy with MFEnumDeviceSources and don’t go anywhere else. They explain that they already provided support…
Logitech’s C930e camera is the first one to be compliant with UVC 1.5 specification: First 1080p HD webcam to support H.264 with Scalable Video Coding and UVC 1.5 encoding technology. […] The result is a smoother video stream in applications like Skype for Business and Microsoft® Lync® 2013. More marketing information there at Logitech. More…
This is presumably a bug in Windows Media Video 9 Encoder in versions up to Windows 7 included (fixed in Windows 8.1 at the very least – wmvencod.dll 6.3.9600.17415). A IMediaObject::Discontinuity call destroys input the DMO it already holds: it reports success, and handles discontinuity correctly. It even drains output as it should, but if in the same time…
To follow up previous post with Media Foundation bug, here goes another one related to property handler for MPEG-4 files (.MP4) and specific property PKEY_Video_FrameRate which reports frame rate for given media file. This is the object responsible for filling columns in explorer, or otherwise visually the bug might look like this: The values of the properties are…
