2012-01-30Deobfuscate ff_huff_build_tree.Reimar Döffinger
I have no idea what the idea was behind the original code, but the new code is equivalent to it. In that loop that places the new node nodes[j] contains always the data of the new node (since the steps are always in order: FFSWAP copies node[j] to node[j-1], j is decremented). Thus nodes[j].no == i and nodes[j].sym == HNODE. make fate still passes and contains VP6 samples which use FF_HUFFMAN_FLAG_HNODE_FIRST. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>

2010-04-20Remove explicit filename from Doxygen @file commands.Diego Biurrun
Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk
