b55cf5f53d libswcale: Fix possible string overflow in test. 
In libswcale/tests/swcale.c, the function fileTest() calls sscanf in
an argument of "%12s" on character srcStr[] and dstStr[], which are
only 12 bytes.  So, if the input string is 12 characters, a
terminating null byte can be written past the end of these arrays.

This bug was found by cppcheck.

a7f94ae583 avcodec/mips: Fix failed case: hevc-conformance-AMP_A_Samsung_* when enable msa 
The AV_INPUT_BUFFER_PADDING_SIZE has been increased to 64, but the value is still 32
in function ff_hevc_sao_edge_filter_8_msa. So, use AV_INPUT_BUFFER_PADDING_SIZE directly.
Also, use MAX_PB_SIZE directly instead of 64. Fate tests passed.

This avoids problems if %4 is the stack pointer
the constraints do not allow %4 to be the stack pointer but gcc 9 may
no longer support specifying such constraints

avio_read may return EOF, leaving the mimetype array unitialized. fail
early when this occurs to avoid using the array in an unitialized state.
