[x264-devel] x264 Intra prediction mode

[eloise vidal]

Hi,
I have a question about the Intra modes used by x264.
I noticed that 3 modes are used in addition to the standardized modes (4
modes(fashions) for blocks 16x16 and 9 modes(fashions) for blocks 4x4):
DC_LEFT, DC_TOP and DC_128.

Are these three modes specific to x264? And if it is the case, how the
encoded stream can be in accordance with the standard H.264?

Thanks in advance,

Eloïse
