VCU supports the following pixel formats. These formats signify the memory layout of pixels. Each format applies at the encoder input and the decoder output side.

If a format is not supported between two elements, the cap (capability) negotiation fails and Gstreamer returns an error. In that case, use a video conversion element to perform format conversion from one format to another.
