Gautam Ramakrishnan 3c06045a8b libavcodec/j2kenc: Fix tag tree coding The implementation of tag tree encoding was incorrect. However, this error was not visible as the current j2k encoder encodes only 1 layer. This patch fixes tag tree coding for JPEG2000 such tag tree coding would work for multi layer encoding.
