      Fix missing initialization of deinterlace intermediate buffer · 8ff92056
      Harish Mahendrakar authored 
      When color format is other than 420p, deinterlacer uses intermediate
buffer for storing chroma output.
For multi-threaded cases, this intermediate buffer was not initialized
in all thread contexts.

      Fix integer overflow error in deinterlacer · b09e66fd
      Harish Mahendrakar authored 
      In deinterlacer, in few cases previous fields pointer was derived
using some uninitialized strides. This value was never used later.

Avoiding the unnecessary pointer increment fixes the integer overflow.

      Allow setting stride equal to width of the clip · 3ea8f1d5
      Harish Mahendrakar authored 
      Current check did not allow stride to be set equal to width of the clip,
once it was set to a larger value.
In one of the AdaptivePlaybackTests, stride is set to a value larger
than current width before decoding the header and then set to value
equal to width as buffers are allocated as per the new width.
Decoder was expecting the stride to be larger value, thus resulting in
buffer size errors.

      Reset buffer managers during reset control call · 4c747e2e
      Harish Mahendrakar authored 
      In some cases, some picture buffer entries in buffer manager were not
released during reset.
Added a function to reset buffer manager entries and called that during
reset control call.
Without this in some call sequences Decoder would run out of picture
buffers and not produce correct output.
