VideoEncoder requires either NV12 or GRAY8 input format for frames. So other outputs, so eg.ispoutput (required for >4K resolution) from ColorCamera, which is YUV420, needs to be converted to NV12 before feeding them to the VideoEncoder. Here's an example of12MP H265 video encoding @ ...
High profile (requires Windows 8) The H.264 video encoder exposes the following interfaces: ICodecAPI IMFTransform Input Types The input media type must have one of the following subtypes: MFVideoFormat_I420 MFVideoFormat_IYUV MFVideoFormat_NV12 MFVideoFormat_YUY2 MFVideoFormat_YV12 For more info...

It requires an NVidia 6xx/7xx series "Kepler" GPU (CUDA capability 3.0), and uses the dedicated GPU's builtin hardware-encoder (NVENC) to offload the H264-encoding process from the host-CPU. This software is "proof-of-concept", so it's...

This encoder requires the presence of the libxvidcore headers and library during configuration. You need to explicitly configure the build with @code{--enable-libxvid --enable-gpl}. The native @code{mpeg4} encoder supports the MPEG-4 Part 2 format, so users can encode to t...
