utvideo: handle empty Huffman trees
If the frame is filled with the same colour, encoder may produce no data and the fill value is indicated by zero code length (the rest of symbols will have 0xFF for code length, meaning invalid). So such Huffman trees should be treated specially. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
