For the above warning I increased the MAX_SLICE value but still getting
the same warning and from the decoder on different machine with increased
MAX_SLICE value where I am not getting the above warning also getting same
frame drop.
following link is the place from where I installed the ffmpeg and x264 to
test the stream-

> I can decode the first 39 frames of the sample with the reference
decoder and while FFmpeg decodes the same 39 frames, only the first three
and the last 20 (beginning with the second IDR frame) are bit-exact, the
remaining 16 show visible artefacts with FFmpeg (that are not reproducible
with the reference decoder).
