[FFmpeg-cvslog] r18896 - trunk/libavcodec/eatgq.c

[reimar]

Author: reimar

New Revision: 18896

Log:
Move eatgq blocks array from the stack to the codec context and make sure
it is aligned as necessary for DSPContext's idct_put.
Just aligning it on the stack would have been possible but less reliable
and without any real benefit.
