Summary0000093: Decoding error when using Data Partitioning with MBAFF
DescriptionEncoding a yuv file using encoder configuration file attached works well. But when trying to decode the .264 bitstream, a fatal error occurs early in the decoding process. Some of the errors are:

- "mb_qp_delta is out of range" after the first frame.
- "Assertion failed: pred_dir<=2, file ...\ldecod\src\macroblock.c, line 4548" after the first frame too.

Additional InformationThe yuv files I encoded are VQEG sequences at SD resolution which I converted to 4:2:0.
TagsNo tags attached.

There is currently no profile that allows using interlaced tools in combination with data partitioning. I'm not even sure if this combination would be completely specified by the standard.

Since the generated stream is not valid H.264/AVC, we should disallow this configuration.

I have restricted DP to Extended and forbidden AFF in Baseline and Extended profiles.
