20 Claims

1. A method of decoding video data, the method comprising:

determining that a reference picture resampling (RPR) mode is enabled;

determining not to apply a template-based inter prediction technique to the video data based on the RPR mode being enabled; and

decoding the video data using inter prediction without applying the template-based inter prediction technique, wherein the inter prediction is a merge mode, the method further comprising:

constructing a merge candidate list for a block of the video data comprising pruning the merge candidate list, wherein pruning the merge candidate list includes excluding merge candidates from the merge candidate list that have at least one reference picture that is a different size than a current picture of the video data; and

decoding the block of the video data using the merge candidate list.
