This however requires the upstream element (for e.g. camera) to support above rates. On AM62A board fastest locally available upstream element source is `wave5 VPU decoder <../../../Foundational_Components_Multimedia_wave5.html>`__ which provides maximum performance of 3840x2160@59 fps with low bitrate files and we were able to achieve same performance after passing this decoded data to E5010 JPEG Encoder as shown in below example :
