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…
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…
MainConcept’s MP4 Demultiplexer in Annex B mode looks, well… slightly excessively broken. H.264 media type with start codes (H264 FourCC, but here they use legacy subtype informally known as MEDIASUBTYPE_H264_bis) do not require parameter sets as a part of MPEGVIDEOINFO2 structure. If they however decided to provide the NAL units, they have to be RLE…

Pulling this out from Blackmagic Design Forum thread: Generally, the recommended interface to the capture cards is the DeckLink API. A DirectShow interface is available, but provides a subset of the functionality available from the complete DeckLink API. Please note that the older, user-space DirectShow filters (DeckLink Video Capture) are deprecated in favour of the…
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…
Every so often there are tasks that need certain reference video or video/audio footage with specific properties: resolution, frame rate, frame accuracy with content identifying specific frame, motion in view, amount of motion which is “hard” for processing with encoder tuned for natural video, specific video and audio synchronization. There is of course some content…
