2015-07-10snow: remove an obsolete av_assert2Andreas Cadhalpun
It asserts that the frame linesize is larger than 37, but it can be smaller and decoding such frames works. Before commit cc884a35 src_stride > 7*MB_SIZE was necessary, because the blocks were interleaved in the tmp buffer and the last block was added with an offset of 6*MB_SIZE. It was changed for src_stride <= 7*MB_SIZE to write the blocks sequentially, hence the larger tmp_step. After that the assert was only necessary to make sure that the buffer remained large enough. Since commit bd2b6b33 s->scratchbuf is used as tmp buffer. As part of commit 86e107a7 the minimal scratchbuf size was increased to 256*7*MB_SIZE, which is enough for any src_stride <= 7*MB_SIZE. Also add a comment explaining the tmp_step calculation. Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>
