b-pyramid with subme 5 or with subme 6 without b-rdo

[Birdy1]

Hi,

I ran some tests with x264 and found that some encodes contain 'glitches'. It looks like sometimes blocks are located at the wrong position.
The glitches are visible with ffdshow (Jun 19 2005) and vlc media player (0.8.2).

Sharktooth build core 47, svn-518.
Intel P4 2.8 GHz
Not overclocked, glitches are reproduceable.

I put the command line arguments of 15 encodes in a table.
constant options: -b 3 -r 5
The input is a avysynth script that produces a video of 400x224 pixels. The output is .264 file.

5799

It looks like b-pyramid in combinations with subme 5 produces glitches.
Also b-pyramid in combination with subme 6, but without b-rdo produces glitches.

Greetings,

birdy

Could you try a more recent libavcodec decoder version or some other codec?
