this is a problem with the h264_v4l2m2m encoder as the SAME exact command works fine when the encoder is switched to libx264. Also, specifying additional parameters such as width, height and bitrate get rid of

3. During encoder initialization, set encodeConfig->encodeCodecConfig.hevcConfig.pixelBitDepthMinus8 = 2 4. The input surface format needs be set to NV_ENC_BUFFER_FORMAT_YUV420_10BIT OR NV_ENC_BUFFER_FORMAT_ABGR 10 or NV_ENC_BUFFER_FORMAT_ARGB10 or NV_ENC_BUFFER_FORMAT_YUV444_10BIT, ...
Temporal AQ uses CUDA pre-processing and hence requires CUDA processing power, depending upon resolution and content. Enabling temporal AQ may result in very minor degradation in encoder performance. 8.5. High Bit Depth Encoding All NVIDIA GPUs support 8-bit encoding (RGB/YUV input with 8-bit ...
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...
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 @ ...

For example, a video codec requires parameters such as video height, video width, and so on. The test application obtains the required parameters from the Encoder configuration files. In this logical block, the test application performs the following: 1) Opens the generic configuration file, Test...

The default input format is 8-bit yuv420p for 8-bit and yuv420p10le for 10-bit. Input format and bitdepth can be selected with--input-formatand--input-bitdepth. Speed and compression quality can be selected with--preset, or by setting the options manually. ...
