There are two h264 files that the sample_decoder cannot decode. Does media sdk support these files? Thanks!

This stream is corrupted. It doesn't have valid SPS. SPS::scaling_list::delta_scale[15] has value 239 which is out of valid ranges:

7.4.2.1.1.1 Scaling list semantics
delta_scale is used to derive the j-th element of the scaling list for j in the range of 0 to sizeOfScalingList − 1, inclusive.
The value of delta_scale shall be in the range of −128 to +127, inclusive.
