1. A computer system comprising:
a picture buffer configured to store a picture;
a video encoder configured to perform operations to encode the picture, thereby producing encoded data, the operations including performing intra-picture prediction for a current block of sample values in the picture, wherein a non-adjacent reference line of sample values is available for the intra-picture prediction for the current block, and wherein the performing the intra-picture prediction for the current block includes:
selecting one of multiple candidate reference lines of sample values outside the current block, the multiple candidate reference lines including the non-adjacent reference line of sample values; and
filtering the selected reference line of sample values; and
a coded data buffer configured to store the encoded data for output as part of a bitstream.
