venc_attr	Encoder attributes. The encoder attributes except the channel width (pic_width) and channel height (pic_height) are static attributes. Once an encoding channel is created successfully, the static attributes are unmodifiable unless the channel is destroyed and re-created.
rc_attr	RC attributes. You need to set the RC mode before setting the RC attributes. The RC attributes are required for H.264/H.265 encoding but are not required for JPEG encoding. The selected RC mode must match the encode protocol in use.
gop_attr	GOP mode struct. Valid only for the H.264 and H.265 protocols.
