Research direction
Start by reproducing the discrepancy with the sample_encode and sample_vpp applications, using vpp.log, vpp-enc.log, and enc.log as the comparison points. Trace the P010 deinterlacing and encoding paths to determine why the combined result differs; done means the combined path produces the same result as the separate deinterlacing and encoding path.
Written by the indexing model from the issue text.
Description
The result of deinterlacing and encoding of intrelaced P010 stream using sample_encode application (vpp-enc.log) differs
from the result of encoding of progressive stream (enc.log) produced by separate invokation of sample_vpp for deinterlacing
of the same input stream (vpp.log).
