Viz Engine supports new codecs using the VML clip player.

H.265

HEVC/H.265 encoded clips can be played using the VML clip player. The clips are decoded on the CPU, which might result in a high CPU load depending on the clip resolution. If hardware-accelerated playback is enabled, it is possible to decode it using GPU; however, not all GPU supports decoding of H.265 encoded clips. It is recommended that the duration of a GOP does not exceed 0.5s.

HAP

The VML clip player in Viz Engine currently supports HAP 1, HAP 5 and HAP Y encoded clips. Clips using these codecs can directly be used by the GPU, which results in minimal CPU performance impact. However, due to the size of the clips, disk performance and general data throughput of the system are affected.

GPU Hardware Acceleration / NVDEC

VML clip player supports NVDEC hardware acceleration for supported codecs like H.264 or H.265. A Clip Player Pro license is required to enable the GPU clip decoding. Without a license, decoding is done on the CPU.

GPU Requirements
