58312b2472 h264: reset data_partitioning if decoding the slice header for NAL_DPA fails 
If it was set before then we can end up trying to decode a slice without
a valid slice header, which can lead to invalid memory access.

It has been checking the number of bits in the offset instead of the

feded990e3 mpegvideo: set reference/pict_type on generated reference frames 
Otherwise the generic code will unref them, which can then result in
last_picture_ptr == current_picture_ptr, which causes deadlocks at least
in rv40.

61ae993957 vc1: Fix intensity compensation performance regression 
Introduced by 28243b0d35

Intensity compensation is always used once it was encountered, because
v->next_use_ic is never set back to zero.

Reset v->next_use_ic, when resetting v->next_luty/uv.

b3189aff8b png_parser: Fix parsing on big endian 
Since pc.state is populated by shifting in from the end of the
32 bit word, the content within pc.state is already in native endian
and should not be read with the AV_R{L,B} functions.

This was already done correctly for state64 above.

This fixes the fate-corepng test on big endian.
