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 @ ...
This feature requires NV_ENC_INITALIZE_PARAMS::enableEncodeAsync to be set to 0, and does not work with MB-based and byte-based slicing on Kepler GPUs. Advanced codec-level parameters Parameters dealing with the encoded bit stream such as GOP length, encoder profile, rate control mode, ...

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...
