ac30754a14 avcodec/dnxhd_parser: fix parsing interlaced video, simplify code
There appears to be no need to treat interlaced videos differently,

ba87f0801d Remove explicit filename from Doxygen @file commands.
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.
